How Does a Load Cell Work?

Posted on by

You can step on a scale at the doctors office or buy fresh produce off a scale at the farmers market. Either way the scale you are looking at includes a load cell inside. But, how exactly does that load cell work?  What does a load cell do?  How does a load cell send weight data to a digital weight display?  Let’s find out.

What is a Load Cell?

For our example, we are going to focus on the most common load cell which is the strain gauge cell.  A strain gauge load cell is a type of device used to measure weight or force. It is commonly used in a variety of applications, such as weighing scales, process control automation, and testing and measurement. The load cell works by converting a force, such as the weight of an object, into an electrical signal that can be measured and send weight data to a computer.

There are several types of strain gauge load cells. This type of load cell consists of a small metal beam or rod, often made of aluminum or alloy steel, which is attached to a base. The beam is designed to flex or bend slightly under the weight or force applied to it.

How Do Load Cells Work?

At the heart of the strain gauge load cell is a thin, flexible strip of material called a strain gauge. The strain gauge is attached to the beam in a specific pattern, known as a Wheatstone bridge configuration. When the beam is subjected to a force, it will flex or bend slightly, causing the strain gauge to stretch or compress. This change in the length of the strain gauge results in a change in its electrical resistance. Continue reading →

Answering Your Questions About Truck Scale Load Cells & Mounting Systems

Posted on by

The majority of this article is provided by Rice Lake Weighing Systems. We have also added a few insights and thoughts of our own as well.

What is a Load Cell?

A load cell, also commonly referred to as a transducer, converts a mechanical force into an electrical signal. Basically, the load cell bends slightly when weight is applied.

In a compression mounted load cell where the load cell is beneath the weighing vessel, like a truck scale, the load cell compresses when a load is applied. This would apply to scales like the Cardinal PRC which has the SCA load cells.

The load cell produces an analog output signal that is proportional to the applied weight or force. The load cell transmits this signal to a digital weight indicator that converts the signal into a digital weight measurement.

When an application requires multiple load cells, each load cell should measure the same proportion of the total load. So in a four load cell system, each load cell should measure exactly one quarter of the load.

Many load cells are proprietary to a specific manufacturer, and may require additional maintenance and costs of ownership. Carefully discuss with your scale supplier all options for load cell systems.

Analog Load Cells
The most common load cells on the market work on the strain gauge principle. All load cells need to convert their analog values to digital before the load’s weight reading can be displayed on an indicator.

Some load cells are directly cabled to the digital weight indicator where the translation occurs. Other cells are connected to summing junction boxes on the scale where the box sums analog readings from multiple load cells, converts it to a digital signal and sends that signal to the digital weight indicator.

Hydraulic Load Cells (pressure transmitters)
Unlike most other load cells, hydraulic load cells do not use strain gauges or internal circuitry. Instead, hydraulic load cells contain hydraulic fluid, and during compression, a change in pressure is created and transmitted via tubing to a summing system where the pressure is applied to an analog load cell to determine weight.

The advantages of the hydraulic load cell typically relate to being resistant to lightning damage. The disadvantage of this type of scale and replacement load cell is the cost.

Analog-to-Digital Load Cells
Some analog load cells perform the analog-to-digital signal conversion within the load cell housing. Although sometimes referred to as digital load cells, the cell still measures in analog. Making the conversion from an analog signal to a digital signal in the load cell allows the system to compare the output of individual load cells and perform a diagnostic analysis based on that information.

Some would say that because the conversion happens in the load cell, sensitive electronic components are increased throughout the scale system, making them susceptible to damage from vibration, moisture and increased solder joints.

Types of Load Cells Found in Truck Scales

Double Ended Shear Beam
This is the most widely used vehicle scale load cell configuration in North America. A double-ended shear beam load cell is a compression load cell that offers a large capacity range from 1,000 to 200,000 pounds.

The double-ended shear beam is secured at both ends with the load applied to the center of the load cell. As in all shear beam designs, the strain gauges are mounted on a thin web in the center of the cell’s machined cavity.

The load cell also has the advantages of being less expensive in high capacity applications than the canister load cell because it does not require checking, making it virtually a maintenance free solution.

Canister
A canister load cell is the oldest load cell type. Also a compression device, it is shaped like a vertical canister and can handle loads from 100 to 1,000,000 pounds.

It is either hermetically sealed or welded to protect the gauges. This load cell’s drawbacks include the fact that it requires checking — installing check or stay rods to hold the weighing vessel in place on the load cell’s top plate during weighing.

For these reasons, many canister load cells on the market today are used to replace older canister load cells on existing weighing systems.

Rocker Column
Some manufacturers prefer rocker column load cells because they are inexpensive. However, they require check rods and bumper bolts that require maintenance, increasing your cost of ownership. The cost saved by the manufacturer on the raw material is passed down the line to the end user in the form of additional maintenance.

Load Cells Are Usually Manufactured as either Alloy Steel or Stainless Steel 

Truck scale load cells are generally made of stainless steel or alloy steel, but most manufacturers offer a variety of load cell solutions that best fit your application needs.

Alloy Steel Load Cells
Load cells manufactured from tool alloy steel elements are by far the most popular cells in use today. The cost to performance ratio is better compared to either aluminum or stainless steel designs. The most popular alloys are 4330 and 4340 because they have low creep (the change in load cell output over time while under load) and low hysteresis (the difference between load cell output readings for the same applied load).

Stainless Steel Load Cells
Stainless steel cells are more expensive than tool alloy steel load cells. They are sometimes fitted with hermetically sealed web cavities, which make them an ideal choice for corrosive, high-moisture applications. Stainless steel load cells that are not hermetically sealed have little advantage over comparable cells constructed of tool alloy steel, other than a higher resistance to corrosion.

Brewery and Beverage Manufacturing Equipment Co. Uses Cardinal Scales in Process and Packaging

Posted on by

In the case study below, we take a look at how a brewery and beverage company that manufacturers equipment for that industry, uses Cardinal Scale equipment in its process. The company that is featured in the case study chose Cardinal products for various reasons, one important reason was the wide range of products that Cardinal offers which allowed the company to utilize Cardinal Scale products throughout and not have to contend with multiple different brands of scales.

Cardinal 190 indicator

The systems provided by IDD provide answers for operations such as keg cleaning, sanitation and filling, flash pasteurization, bottling, and their HEBS (High Efficiency Brewing System). IDD manufactures these intricate and precise equipment systems to meet the distinct needs for their many customers in the beverage industry.

IDD’s reach extends all over the world. While primarily servicing America and Canada, IDD Process and Packaging, Inc. ships to Western Europe and as far as countries in the Oceania area, such as Australia. The burgeoning craft brewery and distillery movement in America and Canada provides IDD with a great deal of business opportunities; however, they are not limited strictly to beer and spirits. IDD delivers expertise in more traditional beverage production, such as grape juice, to more exotic and contemporary drinks, like kombucha and cold-brew tea.

To round out the design of a few of their systems, owner Jeff Gunn researched scale manufacturers to compare products lines and breadth of products. Cardinal Scale was capable of providing the load cells he preferred, along with the digital weight indicators meant to complete filling functions for keg, grain, and yeast managements systems, plus the scales themselves. “Cardinal Scale provided all of the implements that I needed within one company, and that influenced my decision to go with them,” said Gunn.

Cardinal Scale products are featured in Squire Keg Systems, Grain Handling Systems, and Yeast Management Systems. For the Squire Keg series, Cardinal Scale’s model EB-300 scale is coupled with the 190 STORM indicator. The EB-300 weighs the keg that can be moved on a roller platform, and the 190 provides the weight preset programming that is invaluable to precision filling. The Squire Series system can fill up to 30 kegs per hour.

The Grain Handling Systems and Yeast Management Systems utilize Cardinal Scale’s 825 or 225 weight indicator and the company’s TCBSS1KM-4 load cell kits. The TCBSS1KM-4 load cell kits provide the durability and precision needed to take on filling of grain augers, mills, and hoppers or multi-tank yeast propagation systems. The 825 or 225 weight indicator guides the more complex filling functions associated with the aforementioned tanking systems.

So as you can see, the robust product features of the Cardinal Scale Manufacturing lineup of products was a key ingredient in the success of the featured company in the case study. With more than five years of business between the two entities, both the companies are poised to achieve even more success in the beverage industry.

You too can enjoy this same level of success for your business. Contact our sales department to discuss adding load cells under your tanks or adding digital weight indicators to your scales that can collect data that you can then analyze in a spreadsheet on the computer.  Call (919) 776-7737 to get started.

Food Safety Modernization Act (FSMA) and Digital Scales

Posted on by

Food safety is extremely important to all of us. In today’s ultra competitive and fast paced world, it’s imperative that we have laws in place to ensure that the food we eat is as safe as possible.

We hope the article below helps you better understand information about the Food Safety Modernization Act (FSMA). Ultimately we think this information will highlight the ability of Rice Lake’s washdown products to meet your requirements of commercial processing industries. The FSMA info below not only informs producers about how to meet compliance laws, but demonstrates how Rice Lake scales can help prevent food contamination by the integrity of their construction and design.

For all producers, from the farm to the table, purchasing equipment that meets Sanitary Design Principles (SDP) is considered a mandatory preventative measure by the FDA. Our product offerings that are microbiologically cleanable, hermetically sealed and compatible with hostile environments can greatly assist you in adhering to these strict guidelines.

On January 4, 2011, President Obama signed the FDA Food Safety Modernization Act (FSMA) into law. The FSMA brought a much-needed focus of food safety laws into the food processing industry as well as to consumers, and the general public as a whole.

The signing of the FSMA was arguably the largest reform to food safety in the previous 70 years. According to the U.S. Food & Drug Administration (FDA), the FSMA “aims to ensure the U.S. food supply is safe by shifting the focus from responding to contamination to preventing it.” The key focus being prevention versus reaction in regards to food safety, from all aspects and stages of food—from the farm to the table.

The FSMA was spurred into action from an increase in foodborne illnesses in the U.S. The Centers for Disease Control and Prevention report almost 1 in 6 Americans fall ill to food borne diseases each year. Foodborne illness became an issue of public health in the early 2000s, enabling the FDA to set higher preventative standards for food safety and elicit enforcement agencies to hold companies to these standards and contain any potential problems before they become a widespread risk of foodborne illness. To do this, the FDA under the FSMA can order companies to recall when needed.

The primary role of the FSMA is prevention. As noted by the FDA, “for the first time, FDA will have a legislative mandate to require comprehensive, science-based preventative controls across the food supply.” This legislative power ensures all U.S. companies that contribute to the food supply, no matter their size, are subject to the authority of the FDA and their preventative and responding agency.

Under the Prevention section of the FSMA, controls are given to the FDA for the following:

• Mandatory preventive controls for food facilities
• Mandatory produce safety standards
• Authority to prevent intentional contamination

These measures need to be qualified by scientific justifications by the FDA and are enforced by legislation. Under the mandatory preventative controls for food facilities is the addition of a preventative control plan that includes the following:

1 ) Evaluating the hazards that could affect food safety
2 ) Specifying what preventive steps, or controls, will be put in place to significantly minimize or prevent the hazards
3 ) Specifying how the facility will monitor these controls to ensure they are working
4 ) Maintaining routine records of the monitoring
5 ) Specifying what actions the facility will take to correct problems that arise.

Purchasing and using equipment that meets the Sanitary Design Principles (SDP) falls under these mandatory preventative measures as a control to prevent or minimize the possibility of foodborne contamination and disease. Continue reading →

Benefits of Cardinal Digital Truck Scales

Posted on by

Cardinal Armor series Smartcell digital truck scales have several distinct benefits to you, the customer. First there is the heavy duty weighbridge design the Cardinal Armor digital truck scale uses. For example, the steel deck has (12) 12 inch eye beams across the scale but most important is there’s no moving parts under the scale.

ADVANTAGES OF A DIGITAL TRUCK SCALE

With a traditional truck scale, when it comes to debris build-up under the scale, that you typically see in landfills, quarries, sand and gravel businesses; all of that debris can cause problems under the scale and cause binding. Then you will be forced to have folks out there power washing the truck scale, trying to get the scale to work properly because safe linkage systems or load cells that are mounted to piers; the debris impedes on that critical weighing process.

This can often lead to down time for cleaning and can also lead to your scale being rejected when being tested by the State weights and measures inspector.

Another key element of the Cardinal Armor digital truck scale is simple connections which can also lead to limited downtime. Most important there is no power running to the scale other than the home run cable, that’s very important. Do you know what lightning, rain, and snow can do over time to the junction boxes of a traditional truck scale? There’s over a hundred and eight connection points in many standard analog truck scales.

digital truck scales

But, with the armor digital system, there’s ten. There’s five wires that plug into the terminal connector to go to the first load cell and there’s five that you simply wire into the weight indicator in fact Cardinal chooses 225 and the 825 as indicators of choice but most important for you; you want limited downtime for the life of the truck scale.

Common Issues Found on Tanks with Load Cells For Weighing

Posted on by

It’s fairly common to see tanks used in various industries that have load cells or weigh bars underneath, connected to a digital weight indicator. This is a great way to keep track of how much product is inside the tank. These systems generally work very well but every now and then you will find a system that has some errors. Below is a list of problem areas to consider when it comes to tanks and hoppers that have load cells. The information applies to tanks and hoppers currently in operation and also if you’re thinking of putting load cells under one of your existing tanks the information below could help you make a better decision as well.

Probably the number one issue we see is binding. It could be due to something like rigid piping or some kind of attachment that has been added or modified since the scale was put into service. Whatever the case may be, the tank needs to be free and able to get an accurate and consistent weight. We typically see either three or four module systems and that is usually what we recommend.

What type of load cell should you choose? Talk with your scale company to determine what load cell will work the best. The single-ended shear beam cell is designed for low-profile scale and process applications. The shear-beam cell strain gauge cavity contains a thin metal diaphragm onto which the strain gauges are mounted. Typical shear beam capacities range from 1,000 lbs through 20,000 lbs, although some manufacturers offer shear beams up to 40,000 lbs. One end of the shear-beam contains the mounting holes while the opposite end is where the cell is loaded. The cell should be mounted on a flat, smooth surface with high strength hardened bolts. The larger shear beam cells have more than two mounting holes to accommodate extra bolts and keep the hardware from stretching under stress load. The double ended shear beam characteristics are similar to those of the single-ended shear beam. The most common bridge resistance for this load cell is 700 ohm. It is most commonly used in truck scales and tank and hopper applications. Instead of being secured at one end with the load applied to the other end as in the single-ended shear beam, the double-ended shear beam is secured at both ends with the load applied to the center of the load cell. As in all shear beam designs the strain gauges are mounted on a thin web in the center of the cell’s machined cavity. S-Beam load cells derive their name from their shape which is the shape of the letter S. The S-beam is normally used in tension applications. However, there are S-beams available which are bidirectional. They are primarily used for mechanical-to-electronic scale conversions, platform scale and general purpose weighing applications. They vary in size from as low as 25 lbs to as high as 20,000 lbs. When mounting an S-beam, remember to include the side from which the cable extends is the dead portion of the system. Movement of the cable in the live part of the system can be a source of weighing errors.

Aluminum load cell elements are used primarily in single point, low capacity applications. The alloy of choice is 2023 because of its low creep and hysteresis characteristics. Aluminum load cells have relatively thick web sections compared to tool steel cells of comparable capacities. This is necessary to provide the proper amount of deflection in the element at capacity. Machining costs are usually lower on aluminum elements due to the softness of the material. Single point designs can be gauged for costs similar to those of bending beams. Load cells manufactured from tool steel elements are by far the most popular cells in use today. The cost to performance ratio is better for tool steel elements compared to either aluminum or stainless steel designs.  Stainless steel load cells are made from 17-4ph, which is the alloy having the best overall performance qualities of any of the stainless derivatives. Stainless steel cells are more expensive than tool steel load cells. They are sometimes fitted with hermetically sealed web cavities which makes them an ideal choice for corrosive, high moisture applications. Stainless steel load cells that are not hermetically sealed have little advantage over comparable cells constructed of tool steel, other than a higher resistance to corrosion.

Environmentally protected load cells are designed for “normal” environmental factors encountered in indoor or protected outdoor weighing applications. By far the most popular type, these load cells may employ strategies like potting, rubber booting, or redundant sealing to afford some protection from moisture infiltration. Potted load cells utilize one of several types of industrial potting materials. The liquid potting material fills the strain gauge cavity then gels, completely covering the strain gauge and wiring surfaces. While this may significantly diminish the chance of moisture contamination, it does not guarantee extended waterproof performance, nor does it withstand corrosive attack. A second method of protection uses an adhesive foam-backed plate. This protection affords some moisture and foreign object protection. In many cases, manufacturers will use a caulking material to seal the plate to decrease the potential for cavity contamination. A common approach among manufacturers to further decrease the entry of moisture to the strain gauge combines both a potted cavity and a foam-backed plate, in a process called redundant sealing. Yet another strain gauge cavity protection strategy is the rubber boot. Commonly employed with cantilever and bending beam models, the boot covers the cavity and is secured by clamps. While this provides easy access for repairs, the boot may crack if not lubricated regularly, allowing contaminants into the load cell cavity. Lubricating the rubber boot during routine inspections will contribute to the long-term durability of the load cell. Protecting the strain gauge cavity is just one consideration in protecting a load cell from contamination. Another susceptible area is the cable entry into the body of the load cell. Most environmentally protected load cells incorporate an “O” ring and cable compression fitting to seal the entry area. This design provides protection only in applications with minimal moisture. In high-moisture areas, it is safest to install all cabling in conduit, providing both a moisture barrier and mechanical protection. Although environmentally protected load cells keep out unwanted contaminants, they are not suited for high moisture, steam, or direct wash down applications. The only long-term strategy for these applications is to use true hermetically sealed load cells.

Hermetically sealed load cells offer the best protection available for the weighing market. Using advanced welding techniques and ultra-thin metal seals, these load cells handle the extremes of harsh chemical and washdown applications. What makes the seal unique is the process of laser-welding metal covers to protect the strain gauge and compensation chambers. The cavities are then injected with potting or, in the case of glass-to-metal seals, filled with a pressurized inert gas, providing a redundant seal. As a final assurance of the integrity of the seal, a leak test is conducted to reveal any microscopic flaws in the sealing weld. True hermetic protection addresses both the strain gauge cavity and cable entry area. The most advanced cable entry design employs a unique glass-to-metal bonding seal which makes the cable termination area impervious to moisture. Cable wires terminate at the point of connection to the load cell, where they are soldered to hermetically sealed pins that carry signals to the sealed strain gauge area through a glass-to-metal seal. Water or other contaminants cannot “wick up” into the load cell, since the cable ends at the entry point. This design allows for field-replaceable cable, since the connection is outside the load cell. Note, stainless steel load cells are not synonymous with hermetically sealed load cells. While environmentally-protected stainless steel load cells may be suitable for dry chemical corrosive environments, hermetically sealed stainless steel models are the appropriate choice for high-moisture or washdown applications.

It is vital to the performance of a weighing system to select load cells of the correct capacity. Here are some guidelines, all load cells selected must be of the same capacity. Estimate the vessel dead weight, including all piping, pumps, agitators, insulation and vessel heating fluids. Add the maximum live weight of product to be weighed to the dead weight. This is the gross weight of the vessel and contents. Divide the gross weight by the number of legs or support points. This is the nominal weight which will be carried by each load cell. Select a load cell with a capacity somewhat greater than the nominal weight. The following should be considered when determining how much greater the load cell capacity should be; is your dead weight accurate? Will the load be evenly distributed on all cells? Is the vessel fitted with an agitator or subjected to shock loading? Is it possible the vessel will be overfilled, exceeding your live weight value? Will the vessel be subjected to wind or seismic loading? A good rule of thumb is to select a load cell with a capacity 25-50% in excess of the calculated nominal load per cell. Once the load cell capacity has been determined, check that the live weight signal is adequate for the instrumentation selected.

weigh bar kit for tanks

If you’re designing your tank you will want to make sure that you provide an easy way for scale companies to hang test weights evenly all around the tank for testing and calibrating your system. Also, don’t forget to take safety into consideration. Our scale technicians are fairly agile but a little planning up front can make the tanks much easier to test and work on. If you’re in the planning stage, make sure you work with a scale company to ensure that you spec the right parts for your application. For example, we look at several factors such as the weight of the tank, number of legs, and the expected amount of product the tank will hold to determine what capacity of load cell or weigh bar to place underneath.

Finally, you need to think about the environmental conditions such as extreme temperatures, moisture, vibration, and corrosive substances. If any of these elements take place, adjustments such as digital filtering or different products such as hermetically sealed load cells may be recommended.

Strain Gauge Load Cell Designs From Cardinal Scale Manufacturing

Posted on by

But in today’s ultra competitive climate, it’s getting very difficult to find domestic built load cells. In fact we wrote about that not too long ago, you can click here to see that article.

Today I wanted to look at several of the load cell designs that are available from Cardinal that distributors like Central Carolina Scale sell everyday. Of course, load cells convert force into an electrical signal and are a very important part of things like hanging scales, truck scales, floor scales, and many other medical or industrial weighing systems. The load cell sensor detects force and moves the strain gauge, which then measures the movement as an electrical signal that can be used to give power to the scale.

Located in Webb City Missouri, Cardinal Scale Mfg. is one of the largest load cell and strain gauge providers in the U.S. with their own state-of-the-art load cell facility. Cardinal features a wide variety of load cells for use with all weighing systems.

Is It Alright To Cut Load Cell Cable?

Posted on by

A customer recently asked us about cutting load cell cable because the cable was too long for his particular application.  The standard line of thinking is that you should not cut load cell cable because it may void the manufacturer’s warranty. Are there any recommendations for altering load cell cable that might be different than cutting?

Actually, there are several things you can do in these types of situations. Many load cell manufacturers recommend NOT altering (shortening) the load cell cable length, and most manufacturers will not honor the warranty on altered products. However, for the majority of load cell installations, any output change resulting from cable length alteration is easily compensated for with a junction box with trimming capability. Excess cable should be coiled and secured within the junction box (if it will fit.) 

If the excess cable will not fit inside the junction box, it will need to be coiled, and secured externally to the junction box with wire ties, or other suitable means. If the cables are routed in conduit, and excess cable will not fit within the junction box, then the only option may be to cut the cable(s) to length.

load cell cable

What if the load cell cable is too short? Well, we recommend avoiding splicing when possible; however, if you need to gain cable length, it is very important to use the correct splicing technique. Ensure the integrity of the cable is maintained, including voltage, current (signal) ratings, shielding, moisture resistance, and tensile strength. Our recommendation is to use a potted cable splicing kit when possible. If you need a reusable splice point, a sealed junction box may be used.  We hope this helps you understand shortening and lengthening load cell cable for specific applications.
