Displacement sensor for washing machines
When the washing machine is loaded, the displacement sensor DRA measures how much the outer drum drops. It also measures the drum’s deflection during spin-drying. Due to the inductive measurement principle, the sensor provides absolute position measuring for static and dynamic processes. Operation and the washing result are optimized by the load measurement. The displacement sensor provides an output signal proportional to the weight. This permits full utilization of the drum volume and helps to determine the required amount of detergent.
