Triaxial Rosette Strain Gauges

A strain gauge contains a resistive foil pattern bonded to a suspension component. As the component deforms under load, the foil's electrical resistance changes proportionally to the applied strain. This signal is converted into a weight reading, transmitted wirelessly to a handheld display or cloud analytics platform for real-time monitoring.

TruckWeight strain gauge sensors are designed for spring and mechanical suspensions, including spring trailers, drive axles, walking beam suspensions, and Chalmers systems. This makes them suitable for dump trucks, roll-off trucks, hydrovac trucks, and other commercial vehicles using non-air-ride suspension configurations.

Strain gauge sensors typically deliver measurement accuracy within 0.3% to 2% of gross vehicle weight, depending on installation quality and calibration. This level of precision helps fleets stay within legal weight limits while maximizing payload on every haul.

TruckWeight strain gauge sensors offer reliable wireless monitoring up to 500 feet (155 meters), allowing operators to view axle group, gross, and net weight readings from inside the cab or nearby without running physical wiring.

Yes, calibration data is transferable, allowing fleets to move a strain gauge system from one truck to another without recalibrating from scratch. This reduces downtime and simplifies fleet-wide sensor management, especially for operators rotating equipment across multiple vehicles.

TruckWeight strain gauge sensors include a 2-year warranty covering manufacturing defects. Sensors are built to be waterproof, shock-resistant, and corrosion-free, supporting reliable long-term operation in harsh trucking, mining, agriculture, and construction environments.
