What is a weighbridge and how does it work?
A weighbridge, also known as a truck scale, is system of several components that work together to provide weight readings when a truck drives on to the scale. Comprised of a foundation, bridge or deck, load cell system, terminal, and any accessories. These parts work together to provide a weight that can be used for a monetary transaction, inventory tracking, and to check legal weight limits for off-road and over-the-road travel. Weighbridges/truck scales can range in size to accommodate the small farmer, to multi-national aggregate facilities.
How much does a weighbridge cost?
The cost of a weighbridge can vary depending on several variables including:
- size such as truck scale module length or custom wider width,
- material such as steel or concrete deck,
- load cell system purchased with the weighbridge,
- varying installation costs depending on the complexity of the installation,
- weighbridge management software and accessories desired with the scale
When shopping for a truck scale however, it is important to consider the long term costs associated with your purchase. At METTLER TOLEDO, we believe your truck scale should last you 20 years or more. Over time as parts fail, the cost to service and replace components of your weighbridge can add up. Investing in a higher quality scale up front can save you thousands of dollars in the future.
How long does a weighbridge last?
METTLER TOLEDO believes a weighbridge is a long term investment that should last 20 years or more. However this can vary depending on usage, environment and construction quality of the scale. For example, a scale seeing only 50 trucks per day will likely have a longer life than a scale seeing 500 trucks per day. When shopping for a truck scale, it is important to ask questions about the life cycle testing that is done to prove scale longevity. Most companies use FEA computer simulated design testing to prove their scale designs. METTLER TOLEDO goes a step further by performing true life cycle tests on all scale models before they ever see the public market. With our one of a kind module masher, we test our designs between 1 to 2 million cycles - or 20 years of heavy use. This proof, along with our long history of quality truck scales still in use - is a testament to the longevity of our truck scale.
What is the difference between analog and digital load cells?
Weighbridges with traditional analog systems must include a summing box or junction box. Junction boxes are more susceptible to interference from the environment, such as:
- water damage to jbox and cables,
- accuracy fluctuation from temperature,
- failure from lightning strike
Additionally, they are proven to be less accurate than digital systems. POWERCELL load cells from METTLER TOLEDO offer improved environmental protection and accuracy. By removing junction boxes from our POWERCELL PDX systems we have eliminated the biggest cause of weighbridge failure. In fact, our field gathered service data shows that our load cells have a failure rate of less than 0.02% - unprecedented reliability for your truck scale. POWERCELL PDX cells also include additional post signal processing after the A to D conversion that helps to eliminate errors caused by temperature, linearity and hysteresis - leading to a more pure and thus more accurate weight reading on the truck scale.
Are you constantly replacing load cells for your weighbridge? Discover load cell upgrade kits.
Load cell upgrade kits are available for truck scales where the bridge is still in good shape. If your weighbridge is still fairly new, but your load cell system is breaking down often - then you could be a good candidate for an upgrade kit from METTLER TOLEDO. Upgrading your truck scale to a POWERCELL PDX system will give you all the benefits of a new scale, including:
- improved accuracy
- improved reliability
- reduced breakdowns
- less cost in service fees
- a longer scale life
at a fraction of the cost of a new scale.
How can I automatically track the transactions at my weighbridge?
Tracking the inventory and transactions that pass over your scale can be challenging, especially if you are still utilising hand written transactions or out dated software. These systems also allow for a large margin of human error. With DataBridge, METTLER TOLEDO's Data Management Software the process can be fully automated. Benefits include:
- improved inventory tracking/tracing
- reporting functionality
- interfacing with unattended terminals
- plug in technology for user built applications
- advanced fraud prevention
Allowing you to focus on the many other facets of your operation that need your time.
What are the most common ways customers can cheat a weighbridge?
Cheating at the truck scale is becoming more common and cheaters are becoming more sophisticated all around the world. Many businesses spend time and money protecting their facility with gates and guard shacks, but don't know that they could be getting robbed at the truck scale. We have targeted the top 5 ways truck drivers can cheat at the truck scale, including:
- Improper Positioning
- Load Cell Tampering
- Lightening the Load
- Disappearing Goods
- Data Altering

How often should I calibrate my weighbridge?
The frequency of weighbridge calibration will vary from site to site, and is heavily influenced by usage. A truck scale seeing 50 trucks per day will not need calibrated as often as one seeing 400 trucks per day. Additionally the environmental conditions can play a role in how often a scale needs calibrated. The best way to determine the need at your site is to schedule a health check with a METTLER TOLEDO service technician. Based off the results of your check and the information you are able to provide on usage they can make a recommendation on calibration and other preventative maintenance procedures.
Other than calibration what else should I do to care for my weighbridge?
While calibration is an important part of caring for your weighbridge and ensuring accuracy, there are many other preventative maintenance actions that can be taken to extend the life of your scale. A few points to consider:
- how you can keep your scale clean
- scheduled maintenance to avoid break downs
- checking terminal error logs
- inspecting load cells

How Better Technology Can Save You Time and Money
Are junction boxes prone to failure?
These small boxes cause big problems. They must be opened to calibrate and service the weighbridge, allowing moisture and other debris to eventually compromise the sensitive connections and circuitry inside. No matter how well-sealed these boxes are designed to be, they remain the most frequent cause of weighbridge problems. Only POWERCELL PDX digital load cells utilize a daisy chain connection, eliminating the need for junction boxes.
Should I use analog or digital load cells?
Conventional analog load cells are known to have a limited lifespan in weighbridges. A dead load cell can be tricky to diagnose and expensive to replace, requiring a laborious procedure that includes recalibrating the weighbridge. With a failure rate of less than 0.02% and millions installed world wide, POWERCELL load cells offer industry leading accuracy and reliability compared to traditional analog load cells.
What can I do about lightning strikes at my weighbridge?
A single lightning strike can cause devastating damage to load cells, cables, junction boxes, and the terminal, even in weighbridges with substantial grounding features. Our patented technology with Strikeshield lightning protection does more than a grounding rod, by actually diverting a strike away from sensitive components you avoid downtime and expensive repair costs.
My region is prone to wet conditions, what can I do?
Rain, ice, snow, and humidity are the enemy of many weighbridge components, causing harm to the load cell connections. The entire POWERCELL PDX load cell system is submersible, with approvals for IP68 and IP69K wash downs - rain is no problem.
If I experience cable failure, do I have to replace the whole load cell?
Cables can be damaged as a result of failed anti-rotation features that allow the load cell to slowly spin, wrapping the cable around the cell, and pulling on the cable. Rodents also have a habit of “testing” load cell cables with their teeth. When a traditional analog load cell experiences damage, the entire cell must be replaced. With PDX's stainless steel shrouded cables a breakage is unlikely, but if it does occur it can simply be detached by the unique glass to metal locking system. Replacing only a cable is much less expensive than replacing an entire load cell.
