Answering Your Questions About Truck Scale Load Cells & Mounting Systems

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.

Maintenance and Cleaning Requirements for a Truck Scale Weighbridge

Keeping your Truck Scale well maintained and clean is an important part of truck scale ownership. Not only is it good practice to keep your weighbridge clean, it also contributes to a pro active scale maintenance plan and can significantly reduce the risk of equipment downtime and inaccurate weighing.

Before we get very far with this entry, lets clarify one thing… When we say to clean your truck scale, we are typically referring to the areas where mud and dirt can build up and cause weighing errors. Having a pristine scale diamond tread platform is great but that is not what we are referring to when we ask, is your scale clean?

You can see in the picture below an example. The photo on the left shows the scale before cleaning. Notice all the dirt on top of the concrete, especially between the approach ramp and the scale? Now look at the photo on the right after cleaning. You can see the concrete and very little dirt is left at all.

truck scale dirt buildup causing errors

Over time, the build-up of mud and debris can have a negative impact on a weighbridge performance. Compacted mud can set hard and reduce the movement of the weighbridge. This in turn causes reduced accuracy in weighing. Certain types of site environment will suffer more with mud and related issues and weather conditions can also play a part.

Keep in mind, weighbridge cleaning can be a balancing act. You need to remove the mud and buildup so the scale platform can perform correctly. However, the water jet force required to remove dirt and debris from around a weighbridge’s critical weighing points can, if not performed correctly, damage load cells, cables, junction boxes, and summing boards.

When cleaning the scale, the lightest amount of water pressure you can use and still get adequate cleaning, the better.

Weighbridge maintenance should take place as part of a daily or weekly routine depending on the type of site. The build-up of debris and water should be monitored and obstructions should be removed from beneath the scale to provide clearance between the weighbridge and the ground. Otherwise, your scale accuracy will suffer.

Pit weighbridges should be checked to make sure clearances are clean and the correct gap between the deck and pit wall are in place. ‘T’ section rubber can be used to help maintain gaps and should be replaced if worn or damaged. Regular end-middle-end tests with a loaded truck should be carried out to review the accuracy of the scale to see if there are any buildup issues. This basic cleaning and maintenance can be carried out by a site foreman or truck scale weighbridge operator.

If you are a current customer and you are curious about cleaning your truck scale, contact us and we can discuss this further or we can show you the key areas during our next scheduled maintenance visit. If you’re interested in our services, please contact us at (919) 776-7737.

Have you ever heard of Under Weighing Hooks or Below Balance Weighing?

This is a large section of the weighing business that is often overlooked. Of course, many weighing balances have the ability to “under weigh” by the use of a hook that is connected to the weighing mechanism, and much of the time this is used only to weigh items that are too large or bulky to fit on the platform or in the weighing chamber on an analytical balance.

But there is another sector of weighing that is more complex;

Density Determination.

measuring density using a scale

Measurement Density Using a Scale

In this field, we look for the density of our material by using Archimedes Principle of weighing the item in air and then in a liquid. One of the largest industries to use this method of testing is the construction business.

Customers use this for identifying the density of anything from Bitumen in road surfaces, concrete, to core samples taken from the ground where construction is going to take place. Here, an end user will weigh the core sample suspended from the under-weighing hook, (normally in a basket with holes) in air and then, using a bath of water, suspend the core in the water and weigh it again. (Still in the basket).

Seems a  bit complicated? But, with use of a suitable “Below Balance Weighing” device, these measurements are easy to accomplish. The balance will not see the weight of the water, just the effect of the water on the object.

Note! For correct results, the water should be free of contaminants and the temperature of the water is a variable that should be taken into account.

Generally one of these “under balance weighing” balances or scales is not difficult; the customer almost always is familiar with the formulas. For instance, in the construction business often the state has already specified the tests and interestingly, what weighing equipment to use. (Certainly 0.1 g and capacities varying from 3000 g up to 20,000 g)

Density is required for many industries, all you need to do is know which balances have under-weighing capability or, in the case of analytical balances, which ones can have the density kit fitted. The more sophisticated balances have a density program included, so an end user can easily input the data he/she needs to get an accurate and consistent result. Many low capacity balances, such as analytical balances, have density kits that can be purchased; simplifying the process even more.

In fact, the more sophisticated electronic balances have a density program to lead users through the process. So! That is density in solids. There is some scratching of heads when we talk about densities in liquids. How can you do that???

Well, instead of suspending the object in a liquid such as water, you suspend an object of a known weight in the liquid to be tested, sometimes known as Gravimetric Displacement.

In conjunction with the Density Kit, an optional glass sinker enables you to determine the density of liquids. The difference of the weight of the sinker in air and in the liquid is
used to calculate the density.

To recap, the area of density determination with digital scales involves terms like “undeweighing” or “below balance weighing”. Please contact the sales team at Central Carolina Scale (919) 776-7737 or complete our Request a Quote form on the website for assistance with a particular application.

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

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.

Case Study: Intercomp LP600™ to Weigh RVs for Customer Safety

Over the years we have been asked quite a few times about different ways to effectively weigh things like Recreational Vehicles and Trailers that are custom built. One of the choices that we often recommend is one of the wheel weighers from Intercomp such as the LP600.

wheel scales for RV

As you can see from the case study below, the Intercomp LP600 wheel weigher is often a very accurate and flexible choice for companies in today’s world.

As the size and complexity of modern RVs continue to increase,manufacturers and customers must also take into account axle weight compliance and safe weight distribution. While an RV may be weight compliant, RV manufacturers and dealers need to ensure these vehicles are safe to drive once the end user loads personal items, water and fuel.

In the RV market, checking and understanding weight distribution among the vehicle’s axles is becoming increasingly important. Manufacturers, dealers and owners need to have a better understanding of weight for the sake of compliance and safety.

North Trail RV, a dealer for one of the most well-known RV manufacturers in the United States, decided to tackle these potential issues. The company needed an accurate way to measure GVW (Gross Vehicle Weight), and obtain wheel and axle weights, to ensure proper load distribution when fully loaded with personal equipment, fuel and water. The dealer also wanted a way to record and print the data to provide the customer during the final walk through and when customers brought their RV back to the dealer for a standard one-month checkup.

With six LP600™s, North Trail RV recognized an increase in buyer satisfaction based on the additional information provided to each customer after fully loading their RV. The dealer also gained a better handle on what additions and modifications produced the most significant changes in weight distribution. In addition, the scales helped dealer technicians troubleshoot potential problems with suspension components and tires during the one-month checkup. Not only did this decrease the possibility of the customer having service issues in the near future, but it also helped customers understand how critical weight distribution is to proper drive ability and safety while using the unit.

Digital Scales For WinSPC Real-Time Statistical Process Control Software

Today more and more customers want to not only measure the weight of their products, but they also want to capture that information and send it to their laptop computer for data collection and further analysis. There are several ways to do this, and various software programs to help accomplish this as well. We offer various communication types like USB and ethernet and we offer some of the software as well, such as Doran Excelerator.

But today we wanted to mention the WinSPC software. Quite a few customers over the years have been interested in having their digital scales be able to connect to this real time statistical process control software.

WinSPC basically allows companies to compete in today’s worldwide economy since many manufacturers must constantly discover new and innovative ways to cut costs while consistently delivering the highest quality products for their customers. Now it’s important to note up front that we don’t sell WinSPC. The product does seem to be a really nice software though.

WinSPC provides a proven, effective way for manufacturers to quickly improve quality, reduce variation, monitor production or process changes, increase profitability and more. Best of all, WinSPC runs in real-time, collecting data to deliver real meaningful process information directly to operators or to quality engineers, supervisors, and management. WinSPC is a very popular real-time process control tool of choice for manufacturers that need a top of the line solution because WinSPC provides real time SPC capability than quality modules or other process control software products.

A key requirement of most continuous improvement, Six Sigma, and Lean Six Sigma programs is the ability to access timely manufacturing data. WinSPC’s data collection software enable manufacturers to quickly obtain product and process data from nearly any shop floor source, including: serial devices, text files, machines, gauges, databases, and other manufacturing systems. WinSPC’s data collection features offer the fastest, easiest way for quality engineers to quickly gather manual input, connect to devices, and capture data from other manufacturing sources.

The reason we’re mentioning all of this is that if you’re currently using WinSPC (or you’re thinking of purchasing it) and you need to add some digital scales to your company, give us a call at (919) 776-7737.

Our outstanding selection of Doran Scales can be setup to communicate effortlessly with the WinSPC software. Doran Scales offers RS-232 serial, usb, and ethernet connectivity. Many of these scales are NTEP legal for trade and many of the scales are available in stainless steel washdown capability if needed.

With Doran’s Excel Series Indicators line comes an array of “Value Added Standard Features and Options” for a wide variety of applications. In the scale industry, the RS232 Serial Port has been used for communications between scales, computers, or printers since the introduction of the personal computer. In 2002, PC manufacturers agreed to obsolete Serial Ports over time and replace them with USB communication ports.

Doran 2200CW stainless steel checkweigher

Therefore, today’s computers are not always equipped with an RS-232 port, which makes the use of USB absolutely necessary. There are several benefits to using USB communications over RS232 Serial Ports. These include ease of use, reliability, flexibility, and compatibility.

Virtually every company today has an Ethernet network to distribute email, provide Internet access, share printers, and run enterprise wide software. Customers both large and small can leverage their existing Ethernet and PC hardware infrastructure and extend it to the factory floor. The merging of the administrative, control level, and device level networks makes for a less expensive and more connected data network. The result is an efficient end-to-end flow of data from the plant floor to the front office network, where it can be used to better manage operations.

Adding scales to an existing Ethernet network will not adversely affect the network speeds for existing devices. The speed of 10/100Base-T Ethernet networks that provide up to 100 Mbps communication bandwidth clearly eclipses the requirements for scale communications. A typical scale data string only requires about 200 bits, a tiny fraction of the available bandwidth for Ethernet.

As an example of the speed of Doran’s Ethernet option; The Excelerator Data collection software can monitor up to 20 scales with continuous print into one spreadsheet workbook in real time, while only utilizing 0.004% of the total network’s Ethernet bandwidth. Compare this to loading Google on Internet Explorer, which requires quite a bit more network bandwidth! Utilizing the existing Ethernet network without affecting existing devices makes Doran’s Ethernet communications option extremely cost effective.

The point of this article is to simply let you know that if you currently use WinSPC, or are considering purchasing the software, please keep us in mind when it comes to purchasing new digital scales that can connect to WinSPC software. You can reach our sales team at (919) 776-7737 or fill out our RFQ on the website.

Food Safety Modernization Act (FSMA) and Digital Scales

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

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. Continue reading
