Coupling element for a capacitive fill level measuring device

Abstract

Apparatus for capacitive determining and/or monitoring of at least one process variable of a medium in a container, comprising at least one sensor unit with at least one sensor electrode, a housing and an electronics unit, wherein the electronics unit is embodied to supply the sensor unit with a high-frequency exciter signal, to receive a response signal from the sensor unit, and to provide at least from the response signal information concerning the fill level of medium in the container. The apparatus includes, furthermore, a coupling element, which is arranged and embodied in such a manner at least at times to establish a conductive connection between at least one portion of the housing and at least one component of the electronics unit and at least at times to effect a capacitive coupling between the two components.
