Abstract:
A force transducer, in particular a weighing cell, includes a spring body, which deforms under the action of a force or load to be measured, and a sensor that includes two separate sensor parts mounted at different locations of the spring body and that generates a sensor signal which is dependent on the relative position of the sensor parts with respect to each other. In order to improve the adaptation of the sensor to the spring body, one of the sensor parts is attached to the spring body with interposition of an electromechanical actuator and a control device is present, which controls the actuator dependent on the sensor signal in the direction of a reduction in the positional difference of the sensor parts.
