Abstract
A vibration limit switch system and related method is provided with a piezoelectric transmitting- and/or receiving unit, in operable connection with a membrane that can be put in oscillation, and a mechanical oscillation arrangement that is coupled to the membrane, whereby the piezoelectric transmitting- and/or receiving unit is adhered directly, or via an adaptation layer by an adhesive layer, to the membrane. In this improvement, the adhesive layer between the membrane and the transmitting-and/or receiving unit or the adaptation layer has a thickness in an edge area R which thickness is elevated in comparison to a central area Z. This thickness is arranged in differing geometries and amounts to further improve performance.
