Abstract
A device for detecting the filling condition in a container has an electro-mechanical transducer 4 secured on a diaphragm 5, by which transducer the diaphragm 5 is set in vibration. An electrical unit energizes the transducer to produce oscillations of the diaphragm 5. The diaphragm 5 has a holder 1 on which the diaphragm 5 is fastened by means of a cylindrical intermediate member 6. The wall thickness of the cylindrical member 6 is a multiple of the thickness of the diaphragm 5.
