Abstract
A sensor device for continuous measurement of the position of a damping piston in a damping cylinder of a vibration damper, used, in particular, in the spring strut of a motor vehicle, is proposed. The corresponding electronic control and evaluation circuit of such a sensor device is to be located in the immediate vicinity of the sensor element and in particular, the problems related to this measure, involving the sealing of the electronic circuit, with respect to the harsh conditions of the corresponding building space, are solved. This is possible in that the sensor element and the electronic control and evaluation circuit are placed within a damping piston, consisting of a basic body and a cover, and are hermetically enclosed, with respect to the outside, by a surrounding seal, lying between the basic body and the cover of the damping piston.
