Abstract
A fill level switch () for measuring the fill level of a medium in a container (), having a sensor element () for contacting the medium, a sender () for applying an electromagnetic emission signal to the sensor element () and an evaluation unit () for detecting a received signal from the sensor element (). The sensor element () includes at least one cable () for guiding the emission signal. To provide a fill level switch, which is based on a sturdy measuring principle and which allows for reliable cleaning, the fill level switch uses a delay line as the cable () of the sensor element () and the sensor element () has a window () facing the medium in the mounted position of the fill level switch and at least a part of the cable () can be electrically influenced by the medium via the window ().
