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.

Device for detecting the filling level of a liquid in a container

A device for detecting a filling level in a container having an electro-mechanical transducer 4 which is secured to a diaphragm 5 for vibrating the diaphragm 5. Furthermore an electrical device is provided for activating the oscillations of the diaphragm 5. The diaphragm 5 has a holder 1 on which the diaphragm is fastened by means of a cylindrical intermediate member 6. The holder 1 has a holder projection 7 which, with play, is enclosed and engaged by the cylindrical intermediate member 6. The intermediate member 6 is disposed on the holder projection 7 by an elastic play equalization element which is located between the holder projection 7 and the intermediate member 6.

Device for detecting the filling level in a container

In a device for detecting filling level of liquid in a container, a protective tube (6) extends over a membrane (5) which can be placed in vibration by an electromechanical transducer (4). In this way, bubbles which rise in the liquid cannot reach the membrane and induce a false measurement of low filling level.
