Responsible for channeling both power and communication between the load cells and the indicator, load cell cables are an integral part of building a custom scale. Though not just any cable will work. See, load cell cables are selected based on the distance between the two parts, as well as certain environmental conditions like temperature, contact with abrasive or flammable materials, or even rodents.
Before you can know the right type your custom scale project needs, it is best to have an understanding of the different types of load cell cables available.
4-Wire Load Cell Cable
Perhaps the most common cable, the 4-wire load cell cable is used primarily for short distances. As its name suggests, this type consists of four wires:
Power (excitation) +
Power –
Signal (output) +
Signal –
Once connected, the cable should run from the scale to the indicator display. These wires are calibrated and designed to handle the surrounding temperatures. Many custom scale projects use the 4-wire load cell cable since it is more affordable and suitable for most scales. However, should you need additional length or if your scale is in an unpredictable environment, you may need to reconsider the type of load cell cable you are using.
6-Wire Load Cell Cable
Designed for longer distances and more difficult settings, the 6-wire load cell cable offers a lot more options. Again, as the name suggests, these load cell cables have six wires. They contain the four found above, as well as positive and negative sense wires. The long distances that 6-wire load cell cables cover can subject them to changes in resistance, temperature, and dips in voltage. The addition of these two sense wires helps to keep things flowing steadily.
Because they are not thermally compensated as the 4-wire load cell cables are, the 6-wires can be cut and used alongside other cables with no issue – making them perfect for larger commercial custom scale projects.
Types of Load Cell Cable Shielding
While 6-wire load cell cables offer a lot of benefits when designing a project, it is important to note the surrounding environment and opt for shielding that will protect the cable from any outside environmental factors. Below are the most common types of load cell cable shielding.
Hostile Environment Cable
Hostile environment cable is best used in environments that are, well, hostile. Depending on where the scale is being used, the cables may come in contact with harsh or abrasive substances, such as fuel, ether, or even salt. Over time, these substances can damage the cables.
Hostile environment cables are created with a polyurethane jacket that acts as a barrier against these damaging substances, keeping the cable safe and the scale running smoothly.
Rodent Protection Cable
Rodents and their incessant chewing may seriously interfere with a scale’s functionality. If in an environment where there are rats, mice, or other pests, the load cell cable may become enticing – leaving you with hefty costs to replace some or all of the cable.
Rodent protection cable is a type of cable that protects against this pesky situation. The outside layer of the cable is a braided shield making it difficult to chew. And, as an added defense, it is coated with a chemical that will discourage them from wanting to ever take a second bite.
Intrinsically Safe Cable
Flammable gases or liquids or generally hazardous materials can be damaging to load cell cables, requiring added security in the form of a jacket. For intrinsically safe cables, industry-standard blue double jackets are used to protect the cables from exposure to these dangerous materials.
High-Temperature Cable
In environments where the temperatures fluctuate or reach extreme highs, load cell cables need an outer covering that will protect the wires regardless of how hot it gets. A high-temperature cable is designed with a fluorinated ethylene propylene (FEP) jacket that insulates the wires and can withstand the heat without getting damaged.

Airlines could soon require some passengers to step on the digital weigh scale or provide their weight before boarding the airplane.
The initiative, which was described in a recent Federal Aviation Administration (FAA) advisory, attempts to provide new data on average passenger weights as the current numbers allegedly don’t reflect today’s higher obesity rates in the US. By adding this requirement, this would help aircrafts not exceed their allowable weight limit. Essentially, the FAA wants to determine how much heavier Americans have gotten over the past decade.
If this becomes the new standard, the new mandates would require airlines to take surveys to establish average passenger weights for crew members, airline baggage and passengers.
Once they’ve chosen a traveler, an operator may determine the actual weight of passengers by having them step on a scale before boarding the aircraft. However, if that’s not an option, they’re urged to ask each passenger their weight, while making sure to add 10 pounds to account for clothing.
Of course when it comes weighing people in a public setting… privacy needs to be considered, which is why the FAA also provided guidelines on conducting the procedure in a way that protects passenger privacy.
They stipulate that the scale readout should remain hidden from public view while an operator should ensure that any passenger weight data collected remains confidential. Travelers have the option of declining to participate in any passenger or bag weight survey, per the guidelines. You can read much more on this subject by viewing the original article
What do you think about this subject? I guess it makes sense as long as the airlines do a good job with privacy and being discreet. However, what happens if you total up all the passenger and baggage weight and it’s too much? Are certain people asked to leave? Well, whatever you need regarding this subject, we can provide you.

Should I buy a truck scale with weigh bar sensors? The Avery Weigh-Tronix Weigh Bar® was designed to overcome the shortcomings of the traditional strain gauge load cell and to provide the end user with a rugged, highly reliable and linear load sensing device at reasonable cost.
More than twenty years of extensive use in industrial, farm and transportation applications has demonstrated that the Weigh Bar has met these requirements. The unique, robust design of the Weigh Bar is the primary reason for this success.
The Weigh Bar has proven itself over the past 20 years to be one of the world’s most robust weight transducers manufactured today with over 500,000 installations world-wide.
The IP67 Weigh Bar design provides inherent strength and overload protection, while also providing accuracy and high reliability. A significant contributor for this is the positioning of the gauges on the outside of the Weigh Bar. More robust than a shear beam load cell for a given output – a shear beam load cell will reach its peak fatigue point much sooner than a Weigh Bar.
Error Reduction
The unique design of the Weigh Bar allows simple calculations to be made by the indicator, eliminating several types of errors:
• End Loading – When an end load is applied to the Weigh Bar, it is subjected to a uniform compressive strain throughout its length – all sensors detect the same strain. • Torsion Effects – When torque is applied to the Weigh Bar, a uniform torsional shear strain is developed through the length of the bar – both sensors detect the same strain. • Side Loading – When a side load is applied to the Weigh Bar, it acts as a beam, but at a 90-degree angle. When this occurs, the neutral axis of the beam (the point in the beam where neither tension or compression occur) falls directly under the center of the strain gauges. No apparent strain is seen by the gauges. • Vibration –The fine grain structure of aircraft quality steel is resistant to vibration fatigue and induced error. The strain gauges and adhesive used are also vibration and fatigue proven.
Load Cells – The Avery Weigh-Tronix Weigh Bar® Weight Sensor
The exclusive Avery Weigh-Tronix Weigh Bar® is an extremely rugged, highly reliable, load sensing device. Over several decades, the Weigh Bar® has built a reputation for precision, reliability and durability that no other load cell can match.
Weigh Bar – Reduced cost of ownership
Precision machined from aircraft quality, alloy steel, the Weigh Bar® offers excellent repeatability and long-term durability, reducing cost of ownership and need for load cell replacement.
Rugged Weight Sensors
With up to ten times more steel content than shear beams or compression cells, it absorbs impact to minimize peak forces and is virtually fatigue-proof. The Weigh Bar® is proven to resist electrical surges and is protected by a limited warranty that includes coverage against lightning damage.
Accurate Weigh Bar
The sensor’s design automatically cancels the effects of side loading, end loading and twisting, resulting in quick, accurate readings which are achieved regardless of temperature change, vibration, and shock loads on the scale.
Sealed “Load Cell”
The standard alloy steel Weigh Bar® is well protected against harsh environments by an exclusive 5-layer, sealing process. For the most challenging locations hermetically sealed stainless steel weigh bars are available.
Scales are an essential tool for your business. Over time, scales can be subjected to wear or exposure to damaging elements, leading to errors and losses in accuracy. These malfunctions can result in further issues down the line with your shipments and products and should be addressed as soon as possible. Scale calibration is the process of restoring your scale’s accuracy through recording, testing, and maintenance.
The calibration process starts with a standardized weight being placed on your scale. This is repeated several times in order to make an accurate record of your scale’s performance. The reading your scale gives will determine whether it matches the known weight, is within the calibration tolerance range, or so inaccurate that it immediately needs repairs. The calibration tolerance range is a measure of a scale’s ability to accurately measure weight within commercial guidelines. This differs slightly from the instrument range of the scale and is designed to give it optimal performance during regular use.
What is the definition of “calibrate”?
Calibrate, according to the Webster Dictionary, involves ascertaining the accuracy, making corrections, and ensuring that the instrument or device performs within specified accuracy parameters. Calibration is typically carried out by comparing the instrument’s measurements to a known and trusted standard, allowing for precise adjustments to be made as needed.
Why Does My Scale Need to be Calibrated?
Outside of wear or potential damage, there are other reasons why you may need your scale calibrated. If your scale has been in use for a long time, checkups are a healthy way of preserving its function for an even longer period. Scale measurements are also affected by travel and altitude, providing slight variations depending on where the scale was made or if it was used before reaching you. What is known as factory calibration is not as reliable as it seems! Having your scale calibrated by a trusted local professional is key to ensuring consistent performance. A licensed professional is the only way to have your scale pass state inspection and keep its registration, a requirement for commercial work in many states.
What calibration weights are needed to perform a shift test?
To perform a shift test for scales, the calibration weights needed depend on the scale’s capacity according to Handbook 44. These weights should be placed on the four corners of a platform scale or perhaps on on each side of a smaller platform.
What weight test points should I use for calibration?
To calibrate a scale, it is essential to have a minimum of two data points. However, determining the specific weight test points for calibration is not a straightforward matter. The choice of test points beyond the minimum requirement depends on the end-user’s discretion.
To provide a reliable and general example, we suggest the following guidelines for weight test points in a calibration procedure:
Zero: The first test point serves to verify that the scale registers zero weight accurately and remains stable.
Low Capacity Test: This test should involve placing a weight that is approximately 2-5% of the maximum capacity of the scale. It assesses the scale’s performance at the lower end of its capacity range.
Mid Point Test: The next test point involves using a weight that is approximately between zero and the largest weight you are going to use.
Span Test: The final test point should be a weight that is relatively close to the scale’s maximum capacity. You could always use a buildup to assist with fulfilling this test.
There are a few things to consider when deciding how often to get your scale calibrated. The manufacturer’s guide is the first place you should look. All scales come with a suggested calibration frequency that is worth taking note of. How often you use your scale is another factor. Consistent use of any scale will cause inaccuracies, so you may need to have it calibrated more often if it used day in and day out. If the scale is used in an environment that may cause damage it may require even more care. Areas that can cause malfunctioning include those that are dust-filled, electrically charged, or prone to oil spills. Lastly, if your work or business requires highly accurate measurements it may be worth investing in the optimal care of your equipment. Keeping your scale in top form can prevent costly mistakes and setbacks in the future.
What is the allowable accuracy tolerance for my scale?
The allowable accuracy tolerance for a scale depends on several things. For most industrial scales, the accuracy is generally listed as one tenth of one percent. For scales used in legal for trade applications, the tolerances are specified in NIST Handbook 44.
To find more information about a scale’s tolerance, one can refer to the NTEP Certificate of Conformance Database Search. NTEP-approved scales have a Certificate of Conformance (CC or COC) number, which can be used to access details about the scale’s capacity, readability, and accuracy class, among other specifications. The CC number typically consists of five numbers with a dash separating the second and third numbers.
To illustrate the concept, let’s consider a Class III floor scale with a 5000 pound capacity and a 1 pound readability. This scale has 5000 divisions. When the scale is tested at full capacity, it should be accurate within +/- 5 divisions or +/- 5 pounds.
What are the different types of calibration in the scale industry?
In the scale industry, there are several types of calibration and testing. The common method is known as span calibration. This calibration involves determining a zero load point and then testing the scale with a single weight drop point. These two test points are documented and utilized to establish the linear calculation that constitutes a scale calibration.
We do often test scales by using multiple weight drop points to make sure the scales are accurate and linear at multiple points. However, most of the time the actual calibration itself involves just two points, zero and span.

A lot of customers are curious about this question… how long should a truck scale last? Or perhaps it’s phrased like this… how do I know when my truck scale needs to be replaced?
The vast majority of truck scales are located outside. This means the scales have the hot sun blazing down on them all summer (every year). Then, they have the piles of snow on them in the winter (every year). In between all the hot and cold extremes, they have all the rain that you typically see fairly often.
So, with all the weather conditions, that means a truck scale must be able to withstand all the environmental challenges while working reliably and accurately…. For years and years! And, be able to handle 80,000 lb vehicles everyday!
So, how long can I expect my truck scale to last?
That’s a really good question and it’s a question that has a variety of answers.
Depending on the environment and application, most truck scale owners can typically expect a truck scale to last anywhere from 15-30 years.
If your location consistently has over 250 trucks a day going over the scale (or you project it will eventually have that kind of truck traffic) then you will need to choose a truck scale built for that kind of traffic. Choosing an “economy” or standard duty truck scale in that situation may be cost effective now… but will most likely lead you to have a shorter truck scale life and force you into looking for scale replacements or weighbridge repairs sooner than you would prefer.
Sometimes spending an extra few thousand dollars up front will allow you to purchase a heavier duty “HD” scale that will last you significantly longer than the “SD” model. What’s an extra few thousand dollars when you average it out over twenty-five or thirty years of use? Especially if the extra cost helps you gain an extra five or ten years of scale use?
Can I Repair My Truck Scale Instead of Buying a New One?
This is a good question and a common question that a lot of people ask when they have an old truck scale. In most cases, the answer is yes. Depending on the age of the truck scale and severity of the issues, repairing a truck scale can certainly work and be a cost savings.
However, once a truck scale has been in service for over 20 years or so… repairs may not be the best choice. Often you will hear people refer to the scale repairs as “band-aids”. We understand what they’re referring to, but the truth is that truck scale repairs on a 20+ year old scale weighbridge are just that, repairs…
A “band-aid” is supposed to heal your wound and help you get back to 100%. A “band-aid” on a 30 year old truck scale is not going to “heal” the scale. It is simply designed to get a few more years out of the scale before the scale will need to be replaced.
Unfortunately, truck scales that have been repaired often don’t last as long as you would like. One of the reasons is simply the age of the steel and the components. Often the areas that were repaired may be ok after the repair, but then the other areas that were doing ok before the repair, are now starting to fail.
When you think of a truck scale overhaul, the Truck Scale components can usually be replaced… things like load cells, junction boxes, summing boards, etc…, but the core weighbridge construction and integrity are sometimes challenging to rebuild in a cost effective & timely manner…. especially in a scale that’s 25 or 30 years old… or older.
It’s also important to look at the actual repair costs. Sure it can be overwhelming when you see a $80,000 quote for a new truck scale. However, if you attempt to repair and put “band-aids” on a 25 year old truck scale, how much money is that going to cost? Between materials and labor, we’ve seen these repair costs rise above $3000. Plus there is down time where the scale can’t be used.
And even after the scale is repaired, there really is no guarantee or warranty that the scale is going to last X number of additional years. So, in this example, you could spend several thousand dollars on scale repairs that may get you a few more years of service…. or, that $3000 could be used to help pay for a new truck scale.
Planning for Buying a Replacement Truck Scale on Your Terms
Here is one other scenario that we would like you to think about. Let’s say you have a 25 year old truck scale. It has some weighbridge issues and probably should be replaced. But, you and the scale company talk and decide that some weighbridge repairs could likely be made that might give the scale a little more life. Keep in mind at the same time this talk is taking place, new truck scales are readily available with a short 1 to 2 week lead time for fast delivery.
Well, the truck scale repairs take place and it turns out that you did in fact get an extra year of use out of the scale. Unfortunately, the scale now has more weighbridge issues and repairs will likely not make much sense at this point. And, as often happens, the scale failure has just happened right in the middle of your busiest time of the year! And, now it looks like the lead time on truck scales is closer to 14 weeks and there is a 8% steel surcharge now in place.
This scenario that we just mentioned above is all to real and can very well take place. Sometimes if your scale has lasted for two or three decades, it can be a smart move on your part to setup the replacement purchase on your watch (before the scale actually “breaks”). Maybe you talk with your scale company and decide the next time there is an incentive offered, you’re ready to purchase. This can be a wise decision because we all know that no one wants to be in a situation with a broken scale that must be replaced and then be facing extended downtime and a 14 week lead time before your scale can ship.
There are a variety of options in the truck scale market today and, to the casual observer, initial acquisition price may be the only differentiator. However, manufacturers promising great bargains are able to do so only because they’ve cut corners at some stage of the process—design, materials, components, finish or all of the above. While the price may seem attractive now, the eventual failure of a lower quality truck scale could mean a higher total cost of ownership from extensive downtime, increased maintenance costs, lost revenue and premature replacement.
One other note to mention on the subject of money would be taxes and leasing. This article is not going to be in depth on either of those subjects but if you purchase a new truck scale there can be tax advantages (see IRS section 179). We also have leasing programs which can make it easier to afford a larger purchase like a truck scale.
One other thing we wanted to mention on this subject is the overall trend for truck scale pricing. Generally speaking, the price for new truck scales is not going to get any less expensive in 2021 and beyond. In fact, at the time of this article in early 2021, we have received word from at least (3) truck scale manufacturers that there will likely be surcharges very shortly due to steel prices. (So if you’re in the market for a new scale, it might be time to act now!)
2023 UPDATE: Throughout 2022 and 2023 we have seen multiple price increases and lead times from certain truck scale manufacturers that were in excess of 40 weeks!
Believe it or not, the goal of this article is not to be completely gloom & doom about repairing a truck scale weighbridge. There are certainly situations where a truck scale overhaul makes sense. Most of the time, it makes more sense to upgrade components and less sense to try and do major weighbridge structural repair.
However, if you’re in the market for refurbishing a truck scale or purchasing a new truck scale… we encourage you to look at the entire picture and get a true understanding of the costs involved and the expected lifespan with each scenario. The fact is that many truck scale manufacturers are getting really good at building their truck scales to fit existing foundations. This can help to lower costs and lessen the down time when you’ll be without a scale.
Truck scales are important to the daily operations of the facilities that use them. That means that selecting a truck scale is an important decision. Whatever scale you choose (or have chosen), will likely be your scale of choice for possibly two or three decades! Often, a little extra thought or cost up front, can pay off down the road with a durable truck scale that can provide decades of service with proper scale maintenance.

Today, most large vehicle scales are installed with above ground or concrete pit foundations. Depending on state or regional requirements, scales can also be installed in a shallow pit, as opposed to the deep pit required by older mechanical scales.
A pit installation requires less space than an above ground scale since longer approaches are generally required for aboveground configurations. However, pit-styles require sump pumps and drains, and are generally more vulnerable to corrosion due to potential standing water.
PROPER SITE PLANNING FOR TRUCK SCALE FOUNDATION
Before we talk about truck scale foundations, it’s important to think about the overall site to make sure we find the perfect location to actually locate the foundation.
To ensure the longest lifespan and best performance for your truck scale, proper site planning is essential. Your truck scale supplier will help you select the best site, considering the traffic flow of your operation, the best location for a foundation, electrical and conduit requirements, soil conditions and drainage, ease of maintenance and accessory locations.
Before purchasing your new truck scale, it may be helpful to draw out a flow map of your current operations and determine if there are any areas for improvement. It is also important to consider future site use when planning. If you expand your site in the future, will the traffic flow and truck scale location still allow for easy operation?
Creating an efficient traffic flow is important to keep operations running smoothly. Be sure there is adequate room around the scale to perform maintenance and to accommodate driver safety. Is there often a waiting line to use your truck scale? Consider the amount of space needed to accommodate a line of trucks, if needed.
Plot out traffic patterns on your flow map, marking where trucks enter the site, load and/or unload material, and exit the site. Make sure there is plenty of room for drivers to maneuver. Take a test drive with a full-size truck around your plotted traffic flow to test for any tight spots or potential safety issues. Note any special filling or dumping that must take place on site to accommodate for the space needed.
Choosing a Truck Scale Foundation Type
Even the toughest scales are put at risk with a poor foundation… Many factors, such as the slope of the site and soil conditions, must be considered prior to construction. The ground must also be free of any settling prior to scale installation. If the foundation is not properly constructed according to the certified drawing provided by your truck scale manufacturer, your truck scale foundation could shift, causing the scale to be outside acceptable calibration tolerance.
Concrete curing periods can vary depending on the type of concrete being used. Work with your scale supplier to integrate the foundation and approach design into your installation and site plan. Your scale supplier should also be able to recommend local contractors with truck scale foundation experience. Of course all of these decisions will be factors in the overall truck scale installation costs.
Above Ground Foundation or Pit Foundation
Until the early 1970s, all truck scales were mechanical and installed in expensive concrete pits. Today, most scales are installed above ground or in concrete pits with floor foundations. With the benefit of new modular construction, scales can also be installed in a shallow pit, as opposed to the deep pit required by older mechanical scales.
One of the biggest reasons for choosing a pit-type installation is space—or lack of it. A pit installation requires less space than an aboveground installation since longer approaches are generally required for aboveground foundations. However, pit-type scales require sump pumps and drains, and are more vulnerable to accelerated rust and corrosion due to the potential of standing water in the pit.
Truck Scale Foundation Designs
Deep Pier Foundation Typical for colder climates such as those found in northern areas of North America, the deep pier foundation places part of the foundation below the frost line to eliminate the negative effects that freeze-thaw conditions can have on foundations. Discuss with your scale supplier if a deep pier foundation meets your application requirements, or if a deep pier or other specific foundation design is required by your state and region. Similar to isolated pier foundations, the deep pier foundation also requires 2,500-3,000 PSF soil bearing pressure.
Shallow Pier Foundation Shallow pier foundations are a cost-effective solution for truck scale sites with adequate soil compaction and a warmer climate that will not encounter frost line issues. Discuss with your scale supplier if a shallow pier foundation is best suited for your application and meets state and regional requirements.
Floating Slab Foundation A full slab foundation is a continuous or monolithic pour of concrete that runs the entire length of the weighbridge. This is the second most cost-effective type of foundation and is designed for ground that has a soil bearing pressure of at least 1,500 PSF. Discuss with your scale supplier if a floating slab foundation is ideal for your application and location, as well as meets state and regional requirements.
Pit Foundation The pit foundation is available in numerous depths, from two to six feet. Your pit depth should best fit your needs as well as adhere to all federal, state and local requirements.
Drainage Away From Truck Scale
One other thing to think about with truck scale foundations is water drainage and avoiding buildup that can collect under the truck scale or excessive water standing in the pit. Efficient water drainage around the foundation is key to preserve scale components. The installation site should have adequate runoff, allowing water to easily drain away from the scale. Areas with heavy rain and melting snow should take extra consideration when planning site drainage.

One of the things that we try really hard to do is provide our customers with as much value as possible. How do we do that? We do this in many ways through things like factory training, sales training, and product research. One other thing we do quite often is constantly strive to find quality products that are affordable for customers.
However, one of the really challenging things we have to deal with is striking the balance between quality and accurate products. Or, unfortunately, in some instances, good products versus junk.
Unfortunately, the line between a good product and a not-so-good product is getting finer and finer…
I was reminded of this challenge over the past couple of weeks. Recently, I had a line of imported scales from China presented to me that seemed to have a lot of promise. The price was attractive and the visual look of the scales was appealing. However, once I evaluated these items, it quickly became apparent, that although these scales would please everybody’s demand for a low price… they would not meet our standards for accuracy or the demands of our customers.
If you’re an end user, then you face a similar challenge. Perhaps you’re in the market for a counting scale. With minimal internet research, you can find prices on parts counting scales from $100 and up! Of course, the hundred dollar scale is 99% plastic and 1% aluminum and certainly not what we would recommend for anyone looking for a durable and relatively long lasting scale.
The same thing can be said for many types of scales…
Farmers or Market Sellers searching for price computing scales are often easily fooled by the $60 produce scales they may see on popular auction sites only to find out later, (when their state inspector shuts them down), that what they really needed is what’s called a NTEP Legal for Trade certified price computing scale, which is more expensive.
Perhaps it’s a floor scale that you need to weigh pallets each day. Although many floor scales look similar in pictures online, these “pallet scales” feature various components, such as digital indicators & strain gauge load cells, which can vary greatly in quality. The product construction and durability can also vary quite a bit depending on who actually manufacturers the scale platform and how much engineering truly went into constructing it.
So how do you find a weighing scale that meets your budget and is built to last?
These days it’s easier than ever to just buy everything you need without the help of anyone. Just point and click. But many times when you do that, you could be missing out. How does the old saying go? You don’t know what you don’t know…
I recommend contacting your local scale company or a scale company that you have done business with and trust. (Hopefully, we’re included in that choice!) It really does make the process of buying scales much easier when you have a good working relationship with your scale company.
As you work with your scale company representative, they will become a trusted partner in your business. Your scale sales person knows what you’re weighing and the weighing needs of your business. All you need to do is mention what you’re looking to do and what type of weighing device you think that you’ll need.
Pricing and Quotes
Over the years I have seen some really nice scales and I have seen some really bad scales too! I suggest working together with your trusted scale supplier to find products that will meet your requirements while staying within your budget.
The product and sourcing experience that your scale dealer has is invaluable. Don’t forget, in addition to working with you, we also work with hundreds of other customers helping them to find the perfect weighing equipment for their needs. So that product experience and knowledge that we gain can then be applied to your scale search as well.
I also recommend working with a scale company who’s willing to offer various brands of scales as opposed to a dealer who just pushes one brand of scales for everything…
It’s very common for us to recommend different brands for various types of scales. For example, we might suggest CAS retail scales, B-Tek floor scales, Avery Weigh-Tronix counting scales and Cardinal truck scales.
In other words, we base our product recommendations largely off past success and not because we’re trying reach some kind of sales quota.
Final Thoughts
We realize that customers want to find a great deal on whatever it is that they need to purchase. It can be anything from scales to copy paper… everyone wants to find a cheaper alternative that is just as good as what you’ve been using.
Unfortunately, as many of us have found out, often a product is cheaper for certain reasons. We see this all the time whether you’re talking about a portable pallet jack scale or a stationary 4×4 pallet scale. Quality and durability are often lacking with cheap scales.
Let us help you make intelligent scale purchases for your business. We can help you save money while still buying quality scales and weighing equipment. We’re just a phone call away (919) 776-7737. If you prefer, you can also email us or complete our Request a Quote form and someone from our staff will get back to you in a timely manner.
There are many reasons to use digital scales when brewing beer.
It can be for a microbrewery or an international brand. Consistency is first and foremost.
If you created a beer with a special taste, you want to make sure you can recreate that taste in every bottle. If ingredients are not measured properly, the taste can be unpleasant, and the alcohol content (typically referred to as alcohol by volume or ABV) can change.
Specific quantities can allow even new employees who are not familiar with a recipe to recreate the product with ease. A formula can also be tweaked more easily. Weight quantities also make recording easier. Recipes should always be written down with the exact amounts used during brewing. That helps ensure good batches get reproduced, and it can also allow brewers to find out why a recipe did not work.
Measuring ingredients can also help minimize waste by ensuring the right amount of ingredients are used in correct proportions. For home and microbreweries, it can be particularly tricky to scale the right amount of yeast for a first batch, so precision is very important. Even small batches can be ruined by imprecise recipes, which spills all the ingredients, time, money and effort down the drain.
Scales can also help during the carbonation process, depending on your method of choice. Carbonation can be added to beer in two ways: natural carbonation or forced carbonation. Natural carbonation results during the fermentation process of beer; when yeast digests sugar, alcohol and CO2 are the byproducts. This means brewers must carefully measure the sugar and yeast in order to create the proper amount of carbonation.
Forced carbonation is putting beer (post fermentation) in a container and pumping it with CO2 directly. Nowadays, this is the preferred method, particularly for large quantities.
It takes less time to carbonate a batch and forced carbonation allows beer to sit longer, but naturally carbonated beer is smoother and is considered more flavorful. In the end, it comes down to personal preference and equipment availability.
Scales are also used during bottling and to fill cans or kegs. Before fermentation, wort (unfermented beer) is made by boiling the ingredients together. Because some of the water can boil away, it’s important to add more water as need during the fermentation process. Monitoring a keg’s weight can help brewers ensure there is always enough water, and that the beer is not losing carbonation.
The weight of bottles (and their thickness) can also help ensure that carbonation, when combined with temperature and agitation, does not create too much pressure, which could break the glass bottles.
Why measure by weight and not by volume?
Using volume might seem more intuitive since beer is liquid. However, measuring by volume is not as accurate as measuring by mass. The shape of ingredients can dictate how much fits in a cup, while density and temperature can affect a liquid’s volume. Beer goes through numerous processes that can affect volume, including boiling, fermentation, and carbonation. Mass does not have to take these factors into account. That additional precision can improve the beer’s taste and help brewers tweak their recipe to perfection.
Even small balances can also measure a wider range. Take your usual measuring cups and spoons, where you often need multiple items to measure various ingredients. With a scale, you can simply put the ingredients in a container (tared, of course) and fill it until you have the right weight.
What kind of scale do you need for brewing?
You must establish your level of production, and the weight range you will need. If a brewery focuses on seasonal flavors or taste experiments, they will weigh smaller quantities than a brewery focusing on a single product.
Depending on the size of your operation, you’re most likely going to need more than one scale. Usually, micro or home breweries use a compact or precision balance to measure ingredients such as hops, spices, yeast and other fine items, and a stationary pallet scale or a portable pallet jack scale for batches, kegs, mass production and bottling.
