Eurosens DDS BT– wireless axle load sensor for a vehicle with spring suspension. The Eurosens DDS wireless sensor is mounted on the vehicle chassis. The vertical link from the mounting kit is attached to the axle. Suspension deflection under load is converted into vertical displacement of the link and rotation of the DDS sensor shaft arm. A Hall sensor is used as the transducer.The output of the sensor generates an output signal that corresponds to the angular position of the swivel arm, which varies depending on the vehicle’s axle load. To convert the output signal into axle load values in kilograms, it is necessary to carry out a calibration using a vehicle scale.
