ABSTRACT:
A capacitive force sensor is introduced between an actuator and motor vehicle brake shoe and is composed of a closed, metallic hollow cylinder that accepts a plate capacitor. One or more end faces of the hollow cylinder act as force-absorbing membranes and transmit elastic deformations onto the plate capacitor, a measured signal being generated as a result. The force sensor can be utilized in a range of measurement of up to, for example, 2.5 tons, a temperature range from -40 through 350.degree. C. and also exhibits extremely high measuring precision.
