ABSTRACT:
A measuring-cable position sensor is provided in a pressure tight, in particular explosion protected manner, wherein all functional elements besides the cable drum and the measuring cable are located in a pressure tight housing, which is stable enough, so that also in case of an explosion in the interior of the pressure-tight housing section no ignition spark can get through the gaps of the housing to the outside.
