Flexible Strain Gauges and Sensors

"Gauge" and "gage" are simply alternate spellings of the same term; both refer to the sensor that measures strain via resistance change. In the U.S., "strain gauge" is the more common spelling used in technical documentation, product names, and industry literature for mechanical suspension weighing sensors.

TruckWeight's strain gauge sensors deliver measurement accuracy within 0.3–2% of gross vehicle weight. This level of precision helps fleet operators avoid overweight violations, optimize payloads, and reduce reliance on external weigh stations while monitoring axle group and gross vehicle weight in real time.

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 mechanically-suspended commercial vehicles common in mining, construction, and agriculture.

Strain gauge sensors are designed for self-installation in minutes without special tools, wires, or electrical connections. The wireless design connects to a handheld display or cloud-based analytics platform, allowing operators to monitor payload readings from the cab or nearby location.

TruckWeight strain gauge sensors offer a reliable wireless monitoring range of up to 500 feet (155 meters), allowing drivers and yard personnel to read payload data without needing to be directly adjacent to the sensor or suspension component.

TruckWeight strain gauge sensors include a two-year warranty covering the sensor hardware. Detailed coverage terms should be confirmed at purchase, but the warranty reflects the manufacturer's confidence in the waterproof, shock-resistant, and corrosion-free construction of the sensors.
