摘要： The invention relates to a method for determining the piston position of a hydraulic or pneumatic piston cylinder unit, wherein the cylinder jacket and the piston form an electrical conducting path and the piston position is determined with the aid of the inductive and/or resistive properties of the conducting path that is formed. In addition, the invention relates to a piston cylinder unit having a measuring device for carrying out such a method.
