Abstract
A device for determining and/or monitoring the fill level of a medium in a container, including: a first conductive element; a second conductive element; and a sealing ceramic. The sealing ceramic being arranged in a region between the two conductive elements, for the purpose of process separation. A first seal, which is provided between the first conductive element and the sealing ceramic, a second seal, which is provided between the sealing ceramic and the second conductive element, and a control/evaluation unit, which determines the fill level of the medium in the container on the basis of a capacitance measurement or on the basis of a measuring of travel time of measurement signals are also included.
