Device for detecting the position of the piston of a working cylinder

摘要

The invention relates to a device for detecting the position of the piston of a working cylinder. Arranged on the piston is a permanent magnet which cooperates with a sensor fastened in or on the cylinder, e.g. designed as a Hall sensor. The sensor is connected to a supply voltage and transmits an output voltage which varies with a variation in the position of the permanent magnet relative to the sensor. The varying output voltage serves as a measure of the position of the piston.
