Discover Industry Leading Load Cells for Truck and Rail Scales
METTLER TOLEDO vehicle weighing load cells have earned a reputation for superior accuracy and reliability, and for good reason. For years we have provided cutting edge innovation to our vehicle weighing markets to ensure they get the best possible solution for their heavy capacity applications. While many of our competitors don't put value on these solutions, here are just a few of the reasons we are passionate about vehicle scale load cells:
Why is accuracy important for vehicle scale load cells?
When weighing tons of product over the scale, it can be easy for some people to dismiss accuracy. 'You can only be so accurate at that heavy capacity' – but at METTLER TOLEDO we believe this is when accuracy truly matters. If a vehicle scale is giving away +150 lbs. or more per load (which is very common, and often legally acceptable), think of the consequences of how this adds up. Over weeks, months, and years – a company could give away millions of dollars in product and profit.
For this reason, our POWERCELL® family of load cells for vehicle scales provides superior accuracy to ensure operations can weigh with confidence no matter what the capacity.
Why is reliability important for vehicle scale load cells?
For many operations, the vehicle scale is acting as a cash register, buying and selling good by bulk weight. When the scale goes down, operations come to a halt. For this reason, METTLER TOLEDO built special protections and alerts into our POWERCELL® family of load cells. First of all, POWERCELL® PDX® load cells are daisy chained together, eliminating the need for a junction box, the number one cause of truck scale downtime. In addition, all POWERCELL® load cells offer active alerts to any issues before they cause a shutdown.
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.
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.
