Abstract:
A device for determining and/or monitoring the level of a medium in a container or for ascertaining the density of a medium in the container, having: a housing, defining a wall and end faces; a diaphragm; an oscillatable unit; a drive/receiving unit; a tubular inner part; and a regulating/evaluating unit, wherein:said diaphragm closes one end face of said housing, said oscillatable unit is secured to said diaphragm, said drive/receiving unit is disposed in the interior of the housing such that it causes said diaphragm and the oscillatable unit to oscillate, detect the oscillations, said regulating/evaluating unit detects, from the detected oscillations, the attainment of the predetermined level or ascertains the density of the medium, said tubular inner part is dimensioned such that it is positioned between said housing wall and said drive/receiving unit, and said tubular inner part is connected to one of: said housing and said diaphragm in order to thermally decouple said drive/receiving unit from said housing.
