ABSTRACT:
Field device for determining and/or monitoring at least one process variable of a medium in a container. The field device includes: at least one mechanically oscillatable unit connected with the container via a process connection; and at least one driver/receiver unit, which excites the mechanically oscillatable unit to oscillate, or detects the oscillations of the mechanically oscillatable unit, as the case may be. The invention includes that the mechanically oscillatable unit has at least three oscillatory members, that at least one oscillatory member is connected with the process connection at an attachment region, that the three oscillatory members can execute oscillations, which the driver/receiver unit produces, or detects, as the case may be, and that the three oscillatory members are embodied and interconnected in such a manner and the attachment region is selected in such a manner, that an approximately defined transfer of reaction forces and reaction torques occurs between the mechanically oscillatable unit and the process connection.
