Position sensor for measuring engaging stroke length of hydraulic piston-cylinder system, has telescope housing including inner space in which distance measuring system is arranged, where sensor is formed as gas pressure spring/gas spring

摘要

The sensor has a telescope housing including a tubular lower outer housing part (1) and an upper inner housing part (2) that retracts and extends in an axial longitudinal direction in the lower housing part. The housing includes an inner space in which a distance measuring system is arranged. The sensor is formed as a gas pressure spring/gas spring. The lower or upper housing part is formed with a pressure control valve. A connection is formed at the lower housing part that is connected with a fastener for guiding gas into the inner space.
