Abstract

An apparatus for determining and/or monitoring at least one process variable of a medium in a container comprising an oscillatable unit for introduction into the container; a housing, wherein the oscillatable unit is connected with the housing such that the oscillatable unit closes the housing terminally; at least one hollow space in the oscillatable unit which is accessible from an inner space formed by the housing; and a driving/receiving unit for exciting the oscillatable unit to execute mechanical oscillations and for receiving the mechanical oscillations and for transducing them into an electrical, received signal. Inventive features including that the driving/receiving unit is present in such a manner in the hollow space and that the hollow space is filled with a potting material in such a manner that the driving/receiving unit is connected via the potting material for force coupling with a wall of the hollow space.
