Abstract

A distance measuring apparatus for detecting the position of a reflection body in a line structure is provided that includes a sensor device, which has at least one antenna for feeding a transmission signal as an electromagnetic wave into the line structure and for receiving the electromagnetic wave reflected on the reflection body. The sensor device also includes evaluation electronics which are configured to determine the position of the reflection body from the phase difference between the transmitted and the received wave.
