Trailer Tongue Weight Scales

The best option depends on your trailer's suspension type. Strain gauge sensors work well for spring, mechanical, and walking beam suspensions, while air suspension sensors are designed for air-ride trailers. Look for systems offering 0.3-1% accuracy, wireless range of at least 500 ft, and a 2-year warranty.

Quality wireless sensors are designed to be waterproof, shock-resistant, and corrosion-free, allowing them to deliver accurate payload measurements in rain, snow, mud, and extreme temperatures. Look for sensors rated for harsh environmental exposure to ensure consistent readings year-round.

Many wireless sensor systems support transferable calibration data, allowing you to move a sensor from one trailer or truck to another without recalibrating from scratch. This is especially useful for fleets that rotate equipment across multiple trailers or rental units.

Leading strain gauge and air suspension sensor systems achieve accuracy within 0.3% to 2% of gross vehicle weight, depending on suspension type and sensor model. This level of precision helps operators avoid overweight fines while maximizing legal payload capacity on every haul.

Strain gauge sensors are mechanical devices designed for spring, walking beam, and Chalmers suspension systems, while air suspension sensors use temperature and pressure-based technology specifically for air-ride suspensions. Choosing the correct sensor type ensures compatibility and accurate weight readings for your trailer.

Most systems pair with a handheld display or an in-cab touchscreen display showing axle, gross vehicle, and net weights. Some displays also support cloud-based analytics, GPS, trailer identification, and optional serial printers for generating printed weight tickets on demand.
