ABSTRACT:
A method for manufacturing a measuring device for determining and/or monitoring a process variable of a medium in a container. The measuring device includes: A mechanically oscillatable unit, which is securable via a securement to a sensor housing and/or to the container; and a driver/receiver unit, which excites the mechanically oscillatable unit to oscillate, or receives the oscillations of the mechanically oscillatable unit. The mechanically oscillatable unit is excited to oscillate, and the reaction forces and/or reaction moments are detected, which act on the securement due to the oscillations of the mechanically oscillatable unit, that a report is issued, when the reaction forces and/or reaction moments exceed predeterminable limit values, and that, in the case of a report, the mechanically oscillatable unit is adjusted as regards its oscillation properties.
