Patent ID: 8127602

Claim:
A fill-measuring device for determining and/or monitoring the fill level of a container, said device being comprised of: a membrane ( 1 ) which is configured to vibrate; a rigid membrane rim ( 2 ) in which the membrane ( 1 ) is disposed; a drive device ( 4 ) having a drive end face ( 5 ) capable of at least one of, impelling the membrane ( 1 ) into vibration, and converting vibrations of the membrane ( 1 ) into an electrical signal; and an attaching device ( 13 ) for attaching the drive device ( 4 ) to the membrane rim ( 2 ); characterized in that: a part of the attaching device ( 13 ) is disposed in a region extending between the membrane ( 1 ) and the drive end face ( 5 ) of the drive device ( 4 ); and at least one pressure transmission element ( 6 ) is disposed between the membrane ( 1 ) and the drive end face ( 5 ) of the drive device ( 4 ), in a manner such that the membrane ( 1 ) and the drive end face ( 5 ) are coupled together for purposes of transmission of vibration; wherein the pressure transmission element is attached to a membrane shaft which projects from the membrane in the direction of the drive device; and wherein the attaching device ( 13 ) is disposed in the region between the drive end face ( 5 ) of the drive device ( 4 ) and the membrane ( 1 ) in such a way as to be separated by a distance from said membrane ( 1 ).
