Abstract
An apparatus for determining and/or monitoring at least one process variable of a medium in a container or pipeline, including a resonator, which is in contact with an interior of the container or the pipeline, an active element for producing a high-frequency signal in the resonator and an electronics unit, which is embodied to receive from a unit formed of the resonator and the active element an electrical output signal. The electrical output signal is evaluated with reference to frequency.
