摘要： A measuring device is provided for determining a filling level, a limit level, a pressure, or a flow rate of a material to be measured, including: a main body configured to be disposed above the material to be measured; a measuring body configured to be disposed below the main body, the measuring body including a sensor element configured to detect a measurement signal, and a position sensor configured to detect a position of the measuring body, the main body and the measuring body being formed separately from one another and being coupled to one another; and an evaluation device configured to evaluate the measurement signal detected by the sensor element and/or to evaluate the position of the measuring body.

摘要： A fill level radar for continuously measuring a fill level is provided, including a radar arrangement configured to generate and to emit a radar signal toward a surface of a filling material; and an impedance spectroscopy arrangement configured to detect a build-up of deposits on the radar arrangement, or to detect a gas phase of the filling material, by impedance spectroscopy, the impedance spectroscopy arrangement being integrated in the radar arrangement.
