Wireless Strain Gauge Sensors

Listed pricing for the TruckWeight SG-1 is $699.00, while the SG-2 is listed at $799.00. Pricing may vary by selected configuration, readout option, and application. The product information does not publish volume or bulk pricing, so fleets requiring multiple systems should request a quote for current purchase details.

The SG-2 technical specifications state measurement accuracy within 0.3–2% of gross vehicle weight. Actual performance can depend on installation, vehicle configuration, calibration, suspension compatibility, and operating conditions. The SG-1 listing does not provide a specific accuracy figure, so confirm the expected performance for the selected model and application with TruckWeight.

A strain gauge sensor measures changes associated with mechanical strain and converts those changes into weight information after calibration. TruckWeight SG sensors are used for onboard payload and vehicle-weight measurement rather than presenting a standalone laboratory strain value. Calibration data is transferable between trucks, but results depend on the vehicle, suspension system, installation, and calibration process.

The listed sensors are intended for vehicles with spring or mechanical suspensions. Applications include spring trailers, drive axles, walking beam suspension vehicles, Chalmers suspension systems, dump trucks, roll-off trucks, and hydrovac trucks. Confirm compatibility before purchase, particularly when the vehicle configuration differs from the listed suspension and application types.

The systems provide wireless monitoring with a stated range of up to 500 ft (155 m). Weight information can be viewed through a handheld display or cloud-based analytics, depending on the selected option. Wireless performance and useful operating distance may be influenced by the vehicle, installation environment, and surrounding conditions.

TruckWeight product information states that calibration data is transferable when moving the system from truck to truck. The receiving vehicle still needs to be compatible with the sensor and correctly calibrated for its suspension and configuration. Follow the supplied calibration documentation and confirm the transfer process with technical support for fleet deployment.
