A new wireless sensor for mechanical suspension systems offers off-road and severe service fleets a low-cost and easy-to-install alternative to traditional load-cell systems for onboard scales.

The sensors, from Truck Weight, can be easily installed on tandem spring, single point, camelback, walking beam, and Chalmers suspension systems with no modification needed. When used with Truck Weight’s Smart Scale onboard scales, the sensors have been tested to be accurate within a range of 1-2%, the company said.

According to Truck Weight, the new sensors cost roughly 75 percent less than traditional, hardwired onboard scale load-cell systems, while installation time takes about one to two hours.

“After five years of testing and development, we now have a valuable solution that is perfect for mechanical suspension systems in a variety of off-road applications,” said Peter Panagapko, president. “This is a significant advancement in terms of the financial and time-saving gains that we can now offer.”

The sensors allow for an accurate way for fleets to meet payload targets, maximize load efficiencies, and help eliminate overweight violations for a variety of applications for Class 4-8 commercial trucks and tractor-trailer combinations.
