Abstract
An apparatus for determining and/or monitoring at least one process variable of a medium in a container, comprising: a mechanically oscillatable unit; an electrodynamic transducer unit for exciting the oscillatable unit by means of an exciter signal to execute mechanical oscillations and for receiving the mechanical oscillations of the oscillatable unit and transducing them into an electrical, received signal; and an electronics unit, which at least determines and/or monitors the process variable based on the received signal. The invention is distinguished by features including that the electrodynamic transducer unit has exactly one coil, which serves both as a drive element as well as also a receiving element.
