Below is a case study that Cardinal Scale Manufacturing produced recently. The well known scale manufacturer provided weighing equipment including load cells, junction box, and a digital weight indicator to a scale company in Latin America who had actually constructed their own truck scale. All they needed was high quality electronics to finish the project correctly. Let’s take a look below at a few of the highlights.
The Pepsi-Cola factory in Caucagua, Venezuela has recently expanded their production line to include a variety of additional world-renowned brands, such as Gatorade, Yukery Juices, and Lipton Ice Tea. This Caucagua factory is among the three largest soda factories in Latin America. With the increase in production, PepsiCola was looking to install a new 80-ton by 10-kg capacity truck scale. After intensive bidding by local scale dealers, Cardinal Scale’s authorized dealer, Industrias Metarmes, won the bid. They turned to Cardinal Scale Manufacturing for the load cells and junction box, due to the solid reputation Cardinal Scale has built internationally.
Industrias Metarmes fabricated their own truck scale weighbridges and used Cardinal Scale Manufacturing’s electronic components for the application. Industrias Metarmes utilized eight IP68-rated Cardinal Scale model DB 75,000-lb double-ended shear beam stainless steel load cells and 8-cell stainless steel junction box for the scale.
To meet the needs of the Pepsi-Cola factory, the dealer utilized a Cardinal Scale 225 Navigator indicator. This indicator allowed Pepsi-Cola’s logistics operation to store 200 weight IDs, making for a more time-efficient procedure. The 225 indicator can store truck descriptions and material prompts, which makes recalling tare weights quick and simple. The 225 indicator’s RS232 serial port was connected to a printer for printing weight tickets. The alphanumeric keypad was also an important factor in the decision for the 225 indicator making it more convenient for data entry.

Cardinal Scale Manufacturing Company has been awarded a $2.7 million contract in collaboration with Xerox and the Maryland State Highway Administration (MDSHA) to provide virtual weigh stations and continued maintenance for 13 additional sites in the state of Maryland throughout the next three years. The contract includes Cardinal Scale’s Weigh-in-Motion (WIM) vehicle scale equipment, installation, software, maintenance, and on-call services.
Cardinal Scale is using the company’s quartz sensor weigh-in-motion (QWIM) technology to screen trucks based on weights, dimensions, and credentials. This will allow the MDSHA to enforce commercial vehicle regulations and to collect traffic data. The data systems will provide 24-hour information from each installation point on Maryland’s highways and transmit it wirelessly within seconds. This information can be viewed from any computer via cellular connection in real time.
Cardinal Scale’s virtual weigh stations capture data including a picture of the moving vehicle, individual axle and gross weights, axle spacing, vehicle classification, speed, over-height violations, out-of-balance conditions, license plate, and DOT information, as well as time and date. The system will instantly alert law enforcement of any violations by displaying a diagram of the truck’s axle weights along with other information.
Cardinal Scale’s virtual weigh stations are designed to be minimally invasive using small Kistler LINEAS quartz sensors embedded in the road surface. This method captures data of passing trucks without the need to exit the highway or even reduce speed. It operates unmanned and has no notable impact on traffic flow for optimal efficiency.

Companies all across the United States are looking and searching for ways to make their business more efficient and profitable. And it doesn’t hurt to make the the employee’s job a little easier while collecting more data relating to your business. In the article below, a rock quarry does just that with the help of Cardinal Win-VRS computer software.
Cardinal’s powerful WinVRS software keeps traffic moving over your scale by providing fast, accurate collection of data on vehicles, accounts, orders, and materials. Unique, user-defined fields allow you to easily configure the system to meet your needs. A wide range of reports are available to provide period histories, material totals, customer information and more. WinVRS’s convenient file utilities menu allows data to be exported to other applications such as accounting and materials control. NTEP legal-for-trade certified. WinVRS-TOUCH offers all the same great features as WinVRS, but comes with larger fonts and buttons for convenient touchscreen navigation. When a user enters into any WinVRS window with input prompts, an on-screen keyboard appears.
White River Materials has seen their business grow by over 530% since 2002 with truck weighing transactions currently occurring every five minutes on average all day long. This busy shale rock quarry is a division of Atlas Asphalt, Inc. and they have been servicing central and northeast Arkansas with driveway and road base materials, concrete aggregate, and asphalt aggregate since 1968, providing materials for general contractors, homebuilders, municipalities, and other commercial clients. Their specific location in Cord, AR was selected due to the abundance of shale in the area along with its close proximity to a new highway expansion project which made the site convenient for transporting material to many different locations.
White River Materials initially had a system in place for their truck scale operation that only allowed 200 ID’s for trucks, and they had to write all the IDs down on a legal pad along with the tare weights and associated company. Once the customer’s truck was on the scale, the scale operator had to dig through sheets of paper, key the appropriate numbers into the indicator, hand write the job ticket on 3-part forms, subtract the gross and tare weights by calculator, add up the daily net tons of every job material for each respective driver as well as cumulative net tons for job material, and then have the driver sign the ticket.
Daily business is now much easier for this privately-held small business with WinVRS-TOUCH in place for their truck weighing. The USA-made software utilizes an Access database to store all of the vehicles, materials, jobs, and account IDs for every customer, and they now have an unlimited number of IDs. Profiles are easily built for every ID, with a stored tare weight for every vehicle. Continue reading →
When we read about this case study below, we felt that we just had to share it with our readers. A scale company in Iowa installed a very unique scale system which utilizes three LPRA railroad track scales. The system also utilizes Cardinal load cells, 825 digital weight indicator, SB500 Remote Display and Remote Weigh Mobile App for iPad.
The grain facility typically weighs 25 car sets of corn for ethanol or corn sweetener and 18 car sets of beans. The Cardinal railroad scale was purchased instead of an overhead load-out weighing system and offered significant savings for the customer. The way the system works is an eastbound train pulls railcars onto the scale to get the Tare weight on scale platforms #3 and #2 and then Gross and Net are determined when the train pulls forward onto scales #2 and #1 with a special tare. Custom software developed by Cardinal Scale and installed in the 825 Spectrum weight indicator allows the operator to turn scales on and off as railcars come across them to prevent weighing railcars when unnecessary. The 825 indicator’s special software also incorporates a temporary Tare weight for the operator to get a target fill weight using a fill program to fill up or top off the last part of a railroad car. Then, cars are pulled forward by a trackmobile into final weighment position to receive their Gross, Tare, and Net weights.
The USA-made 825 indicator is connected via Ethernet cable to a wireless router which has a long-range radio (wireless access point) attached to it for Wi-Fi output. This allows the operator in the trackmobile to wirelessly control the railroad scale through an Apple iPad using Cardinal Scale’s Remote Weigh mobile app. This system replaces their old method of two-way radio communication back and forth from the scale house and allows them to use one less person for the operation. The trackmobile operator can move the railcars and see when each car is positioned on the scale for weighing without ever leaving the cab. This efficiency allows the grain facility to reduce the amount of man power needed from five people down to four
people. Case Study (pdf file)
Even though we mainly focus on truck scales, we thought many of our readers would appreciate the new Cardinal LPRA railroad track scale which is now available. Cardinal Scale Manufacturing low-profile LPRA railroad track scales come with either electronic or hydraulic USA-made stainless steel load cells, up to 270-ton capacity, rugged steel weighbridges, Wi-Fi and mobile app options, NTEP and Measurement Canada legal-for-trade certification, and E-80 Cooper AREMA rating. Twenty different standard models are available from Cardinal Scale in different lengths and capacities to accommodate any combination of car length, and custom applications and configurations are also readily available.
Mounted above ground in a shallow, concrete foundation, Cardinal’s LPRA rail scale is engineered to stabilize shifting ballast resulting in weight errors. Installation is rapid, simple, and can be handled locally requiring usually only about two days. Weighbridge sections arrived assembled, ready to set in, and load cell assemblies are easy to install. Grain dump grating is also available to expedite the unloading process. Accuracy is in accordance with NIST, AAR, and AREMA requirements (railcars uncoupled at both ends).
Often end users will ask about adding a printer to their existing scale or perhaps to a new system they are requesting. And quite often the end user is under the impression that adding a printer to a scale is as simple as going to the electronics store and buying a computer printer and plugging it into the scale via USB. Unfortunately, adding a printer to a scale system is not usually a plug and play application.
So to answer the question, why is my label or ticket printer not working with my indicator? Let’s take a look at the answer provided by Cardinal Scale. Label printers come from the factory set in a graphics mode (called page mode) while Cardinal indicators send data in a line mode from the print tab setup. It is often possible to set the label printers to line mode, but this can be difficult and is ultimately the less effective option. We recommend creating a graphic-type ticket using Cardinal’s nControl software that can be used to create custom headers and set font sizes. This has been proven to work well with the label printers that Cardinal sells. Works great when designing print outs for indicators such as the 190, 205, 210, or 225.
For the next few entries we are going to answer some frequently asked questions about buying a truck scale. In the first entry we answer the question below.
What exactly is the difference amongst a full-length truck scale and an axle scale? Which variety do you notice recyclers employing most frequently?
An axle scale is designed to weigh only a single individual axle of a large vehicle at one time and may possibly give an overall total gross weight at the conclusion of weighing the truck. Axle scales are frequently portable, but could also be permanent installations as well. For example, check out the video below.
On the other hand, full-length truck scales, usually 70 feet long can weigh the entire truck (all axles included) in a single weighment, so axle scales need more time to weigh up a truck than full-length weighing machines. Recyclers will normally use full-length 18 wheeler scales due to the fact axle scales will not be NTEP legal for trade, which is needed in the recycling industry.
Recycling businesses are having to pay men and women depending on the load of the timber in their particular vehicle load, so consequently it’s important for the scale to be NTEP listed for correct weighments. In brief, the process involves individuals bringing in their recycled copper, the metal recycling company compensates these individuals for it depending on the weight displayed on their truck scale, and so the recycler then usually utilizes a railcar to deliver the material to steel mills.

One of the questions that quite a few folks ask about from time to time is How do I install a weight alarm buzzer into my Cardinal Scale weight indicator to let me know when a truck is on my scale? Of course the driver could just call the scale operator using a cell phone. Or, the truck driver could lay on his horn until somebody noticed. Well, those are probably not the best choices. This installation is most commonly requested for the Cardinal 225 indicator, although a similar setup can be done on the advanced 825 from Cardinal.
For the 225, you will need to purchase Cardinal part number 6620-0016 which should mount in place of the larger gland connector in the back of the 225. The red wire for the buzzer will plug into pin 2 of the P15 connector. The black wire will plug into pin 10 of P15. Once this is connected, enable the weight alarm within the ID Storage mode of operation settings.
Cardinal Scale’s EPR-LF series portable vehicle scales are the ideal answer when a scale is needed that can be moved from site to site. Industries such as rock quarries, sand and gravel pits, and logging companies must relocate equipment from time to time to maintain efficient product flow. The complete scale is contained in modules which are furnished with lifting eyes for easy moving. Simply lift, move, and lower the scale to its new location for weighing with minimal time and effort necessary. Optional steel ramps, guide rails, weight indicators, remote displays, and lifting kits are also available for the EPR-LF truck scale.
Standard features of the scale include Checkered Steel Deck, Durable Anti-Corrosion Powder Paint, Heavy-Duty Structural Steel Tubing, Low-Profile 16-inch Overall Height, Made in USA Quality Measurement Canada Certified, NTEP Legal for Trade, Self-Contained and Portable, and SnapStream Wireless Connection Between Scale Decks and Indicator.
Best of all, SnapStream wireless connectivity comes standard with the EPR-LF. This allows wireless communication between scale deck modules and the Cardinal Scale weight indicator for seamless integration between all scale components and alleviates the need for rewiring every time the truck scale is moved. SnapStream is a digitally controlled weighing and diagnostic system that is NTEP legal for trade and designed utilizing the Zigbee protocol for reliable and accurate weight and data transmission for truck scales.
Designed for easy transport, each completely self-contained EPRLF scale consists of 16-inch-high modules fabricated to minimize overall height and maximize strength. Heavy-duty structural tubing is placed in strategic locations to support heavy vehicle loading. Cross members and other lateral structural members provide rigid support for the heavy-duty checkered deck plate. The EPR-LF may be placed on compacted surfaces or timbers for an economical installation (applicable in states which approve temporary installations). Contact your local weights and measures office for specific
requirements in your location.
We were reading the cost justification guide from Cardinal Scale recently and they brought up a good point. It is surprising how many truck scales are manufactured by one company and use load cells from yet another company and a digital weight indicator from yet another company. So if something breaks, where does responsibility for the scale begin and end with each manufacturer? Cardinal Scale Manufacturing is one of the very few companies that manufactures not only the scale weighbridge structure but the load cells and instrumentation that go with it to complete the scale. With Cardinal you really do have single source responsibility and reliability. If you’re thinking about a Cardinal Truck Scale or better yet thinking about going with a hydraulic truck scale, read here.
◾As previously mentioned, lightning and water are the two most common sources of load cell failure. Often truck scales are placed in locations subject to flooding or are subjected to routine high-pressure washings. While digital and analog load cells are sealed against the entry of moisture, they often fail due to damage to a seal or abrasion of a cable jacket allowing entry of moisture. Analog and digital load cells are both subject to lightning damage. The extremely small strands on a strain gauge are especially sensitive to voltage surges. Hydraulic load cells have neither strain gauges nor electrical wire and are immune to damage from both water and lightning. If your scale will be in a location subject to spring time thunderstorms, you should give serious consideration to Cardinal’s Guardian hydraulic load cells.
◾Guardian hydraulic load cells operate by sensing weight via fluid pressure, which means that they require no power within the scale itself. You won’t lose any operational time when lightning or other power issues strike at the scale location. Guardian load cells carry a lifetime warranty against lightning and power surges.
◾Unfortunately, it is a fact of life that if something can be overloaded, it will. Same goes for shock loading on a truck scale. Whether you’re filling trucks with rock or ore, shock loading will take place. Both analog and digital load cells use a steel spring element to sense the load. Applying a shock load, even one less than the capacity of the load cell, can and will cause permanent damage to the load cell rendering it unusable. Cardinal’s Guardian hydraulic load cells, on the other hand, act much like a shock absorber on your automobile dissipating the shock load in the hydraulic fluid.
◾Hydraulic tubing from the load cells is terminated at the scale house by a non-conducting Goodyear rubber line. This creates an important barrier of protection, preventing lightning from traveling into the scale house where your load-sensing digital weight display is located.
◾If you’ve ever experienced costly downtime and repairs due to lightning or a power surge, the Guardian hydraulic truck scale can help you save in the future.
We can definitely confirm to you that customers are buying hydraulic truck scales. Yes, they are more expensive than traditional truck scales with analog load cells but for quite a few customers, they feel the added costs up front are worth it. Lightning and water are the two most common sources of load cell failure. Often truck scales are placed in locations subject to flooding or are subjected to routine high-pressure washings. While digital and analog load cells are sealed against the entry of moisture, they often fail due to damage to a seal or abrasion of a cable jacket allowing entry of moisture.
