Abstract

Position transmitter comprises a telescopic housing whose lower part holding the displacement transducer (10) is joined to a hydraulic cylinder (4) and whose upper part holding a measuring stick assigned to the transducer is connected to a guide piston (5). A bending rod (24) connects the upper part of the telescopic housing to the plate of the guide piston. The longitudinal axis of the bending rod runs in the lifting direction of the hydraulic cylinder.
