Static Truck Scales vs Weigh In Motion

Posted on by

When it comes to weighing commercial vehicles, there are two main options: static truck scales and weigh in motion scales. Both types of scales serve the same basic purpose. To accurately measure the weight of a vehicle, but they differ in terms of how they are used and their specific capabilities. 

Traditional “Static” Truck Weighing

Static truck scales are the more traditional option. These truck scales consists of a weigh bridge that’s usually around 70 feet long, that’s usually above ground and installed on a concrete foundation. The vehicle drives on to the scale to be weighed. Static truck scales are typically found everywhere from feed mails to recycling centers to weigh stations. They are used to weigh vehicles that are fully stopped.

Static Weighing Advantages

One advantage of static truck scales is that they are accurate because the vehicle is fully stopped and stationary when it is weighed, the accuracy is better than a weigh in motion scale in which the vehicle never stops. Additionally, static scales are common. They’ve been utilized for many years. Technicians know how they work and spare scale parts are readily available, and the vast majority are legal for trade.

Disadvantages of Static Weighing

However, there are also some disadvantages to using static truck scales because the vehicle must come to a complete stop to be weighed. These scales can cause delays and disrupt traffic flow. Additionally, a static scale takes up a lot of room. The scale weigh bridge is usually at least 70 feet long and requires plenty of room for the truck to enter and exit. You also have to pour a large concrete foundation for the static scale to be placed on. Therefore, static scales are typically more expensive than weigh in motion systems.

Weighing a Vehicle While It’s Still Moving

Weigh in motion scales on the other hand are designed to weigh vehicles while they are in motion. These scales use sensors to accurately measure the weight of a moving vehicle, without the need for it to come to a complete stop.  

Weigh In Motion Advantages

One advantage of weigh in motion scales is that they allow for the weighing of vehicles without disrupting traffic flow.  Because the vehicle does not need to come to a complete stop.  weigh in motion scales can help to reduce delays and improve overall efficiency. Additionally, weigh in motion scales can be installed in a smaller area since the scale platform itself is only a fraction of the size of a traditional truck scale. Continue reading →

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 does a load cell work

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 →

Why it’s Important to Use Accurate Scales and Load Cells on Concrete Batching Hoppers

Posted on by

Using scales at a concrete batching facility is extremely important to guarantee the quality and consistency of the final product. In fact, it can be argued that the use of scales and weighing equipment, is one of the most critical aspects of the entire concrete production process. There are several reasons why this is the case, which we’ll discuss below.

Accurate Ingredient Mix

Using scales and strain gauge load cells helps to ensure that the correct amount of ingredients are used in the concrete mix. Concrete is made up of a mixture of cement, water, sand, and aggregate, and the proportions of these ingredients play a major role in determining the strength and durability of the final product.

If the amounts are not accurately measured, the concrete may be too weak or too brittle, which can result in costly failures or repairs down the line. By using hopper scales and load cells to measure the exact quantities of each ingredient, concrete producers can ensure that the batch is consistent and accurate.

Quality is important. But, utilizing scales at a concrete batching facility can also help to reduce waste and save the concrete company quite a bit of money. If the proportions of ingredients in the concrete mix are not accurately measured, it can lead to excess or shortages, which can result in wasted materials and additional costs. By using hopper scales with strain gauge load cells to measure the exact quantities of each ingredient, concrete producers can become more efficient. 

Load Cells for a Hopper 

Scales and weighing equipment is used at batch plants. Strain gauge load cells are installed on hoppers to weigh the elements of the mix. It is very important that any moving parts of the batching system are inspected on a regular basis for any buildup or seizing.

Furthermore, using scales at a concrete batching facility can help to improve efficiency and productivity. Accurate measurement of ingredients using scales allows for the production of consistent batches of concrete, which can be processed more quickly and efficiently. This can help to reduce the time and labor required to produce each batch, resulting in increased productivity and profitability for the concrete producer. Continue reading →

Understanding fundamental truck scale basics and how a truck scale works will help you know which questions to ask your local scale distributor to ensure you purchase the truck scale style that fits your needs with the options and accessories that can enhance your application.

 

Whether monitoring a vehicle’s weight for safety guidelines or to complete business transactions, you should know what the info determined by a truck scale means to your business.

For example:

Gross weight is the total weight of the vehicle and loaded product.
Tare weight is the weight of only the vehicle.
Net weight is the weight of only the loaded product.

how accurate are truck scales

Today, most scales at solid waste facilities or recycling centers 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 above ground configurations. However, pit-styles require sump pumps and drains, and are generally more vulnerable to corrosion due to potential standing water.

The truck scale’s driving surface is called the weighbridge. Weighbridges are composed of steel or concrete decks, and are typically manufactured in modular designs that are connected together during installation.

weight indicator

The indicator, also called a controller, or terminal, can display basic weight functions, as well as serve as the command center for a weighing system with truck in & out programs to control the entire truck scale system, including any remote displays and ticket printers.

Load cells are vital to truck scale performance. There are various types of load cells, but they all basically have the same function—to accurately measure weight on the scale. How do load cells work, you may be asking?  All load cells take an analog measurement, and then that signal is converted to a digital output either at the load cell, junction box, or in the scale indicator. Load cells are typically constructed of steel and are integrated within the weighbridge, usually at the corners of each module.

A junction box properly manages multiple load cells. By matching the signal of each load cell and summing them into a signal that’s sent to the indicator, junction boxes equalize the system for accurate and reliable weight readouts.

Handwriting a ticket for each weighment is time consuming and tedious, and also leaves room for human error. Ticketing kiosks, scale data management software, and/or ticket printers eliminate those problems. Most states also require ticket printers and Remote Displays.
