Abstract
A fill level switch (1) for measuring the fill level of a medium in a container (2), having a sensor element (3) for contacting the medium, a sender (4) for applying an electromagnetic emission signal to the sensor element (3) and an evaluation unit (5) for detecting a received signal from the sensor element (3). The sensor element (3) includes at least one cable (6) 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 (6) of the sensor element (3) and the sensor element (3) has a window (7) facing the medium in the mounted position of the fill level switch and at least a part of the cable (6) can be electrically influenced by the medium via the window (7).
