The sensor measures axle load on vehicles with spring suspension by measuring the distance from axle to frame. It is installed on vehicles with leaf-spring suspension, has an IP55 rating for dust and water protection, and is resistant to short circuits and reverse wiring. The sensor output is a stable voltage between 1.54 and 3.46 V that does not depend on vehicle voltage and remains functional from 18 to 30 V. Installation involves mounting the lever arm, making electrical connections, performing a calibration by partially unloading the vehicle and correlating weight readings with sensor voltage output, and testing the calibrated sensor.

18. CalibrationCalibration
1. Calibration is performed by
weighing the truck or axle
2. Calibration is performed by
weighing cargo

19. Calibration by unloadingCalibration by unloading
Calibration can be done by partially unloading the truck, each time
measuring the weight on weighting bridge and output voltage from sensor.
Unloading shall be done in 5 to 10 parts and more, to get as many
calibration points as possible.
