Title: APPARATUS FOR DETERMINING AND/OR MONITORING AT LEAST ONE PROCESS VARIABLE
Abstract:
The invention relates to an apparatus (1) for determining and/or monitoring at least one process variable of a medium (11) in a container (12), having a vibratable unit (2) for insertion into the container (12), having a housing (10), wherein the vibratable unit (2) is connected to the housing (10) in such a manner that the vibratable unit (2) closes the housing (10) at the end, and wherein at least one cavity (3) is made in the vibratable unit (2) and is accessible from an internal space formed by the housing (10), having a drive/receiving unit (4) for exciting the vibratable unit (2) to vibrate mechanically and for receiving the mechanical vibrations and converting the latter into an electrical reception signal. The invention is distinguished by the fact that the drive/receiving unit (4) is inserted into the cavity (3) and the cavity (3) is filled with a potting material in such a manner that the drive/receiving unit (4) is connected in a force-fitting manner to a wall of the cavity (3) via the potting material.
