Abstract

A pressure fluid cylinder (1) including an indicating device (8,10) for indicating the piston position inside a cylinder tube, said indicating device (8,10) including on the one hand a piston position sensor fastenable in a chosen position along the length of the cylinder tube for detecting that the piston is present in said position, on the other hand a light source, which is activated so as to indicate when the piston is present in said position. The cylinder is distinguished in that the light source is connected to the piston position sensor for forming a sensor unit (8), that the sensor unit (8) is fastenable in an axial position in an axially extending channel (7) in the wall of the cylinder tube, and that the channel (7) has a light transmitting element (10,16), located in a position along the channel for emitting light from the sensor unit to the outside of the pressure fluid cylinder. <IMAGE>
