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.
