Capacitive filling level measurement sensor, especially for motor vehicle use, has a capacitive sensor element that generates a level-dependent frequency signal and signal processing and control elements contained in a housing

摘要

Capacitive filling level sensor (1) has a capacitive measurement element (2) with a cylindrical base shape, a housing connected to it and a measurement device contained within the housing. The device comprises a power supply (11), a sensor connection element (5) for generation of a frequency signal from the measurement element, a parameterization device (6) with a storage component (10), a control unit (4) and a signal output component (7).
