Capacitive measuring device for determining and/or monitoring filling level of e.g. liquid, provided in container, has intermediate layer electrically conductive and surrounded partially by electrically isolating insulation layer

摘要

The device has an electronic unit supplying a sensor unit (2) with an excitation signal and receiving a measuring signal from the sensor unit. The sensor unit exhibits a base (5) that is electrically conductive, and is surrounded partially by an intermediate layer (6). The intermediate layer is electrically conductive and mechanically flexible, and is surrounded partially by an electrically isolating insulation layer (7). The intermediate layer and the insulation layer are made of an identical base material e.g. ethylene-tetrafluoroethylene.
