The present disclosure relates to an apparatus for the position determination of a cylinder piston located in a cylinder liner, said apparatus comprising: a port for coupling an electrical signal into or out of the interior of the cylinder liner, wherein a signal coupled into the interior of the cylinder liner interacts with the cylinder piston. The present disclosure is characterized by a unit for determining the position of the cylinder piston which is connected to the port and which is configured to determine the position of the cylinder piston in the cylinder liner with the aid of a vectorial measurement of a signal decoupled from the cylinder liner.

Apparatus and method for the position determination of a cylinder piston

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.
