Eurosens DDS-A
Introduction to the Product
The Eurosens DDS axle load sensor is designed to measure the displacement of a vehicle’s leaf spring suspension. Its operation is based on converting the sensor lever’s rotation angle into an output voltage using a magnetoresistive sensing element as the transducer.
The sensor is mounted on the vehicle chassis, while a vertical linkage from the mounting kit connects to the axle. When the suspension deflects under load, this movement causes the rod to move vertically, resulting in the rotation of the DDS sensor’s shaft arm.
A Hall-effect sensor is used as the transducer to generate an output signal corresponding to the angular position of the swivel arm, which changes with the axle load. To translate this output signal into axle load values (in kilograms), the system must be calibrated using vehicle scales.
