ABSTRACT:
The invention relates to a level meter (1) with an outer oscillating body (3) and an inner oscillating body (4), which bodies are coaxially positioned relative to a longitudinal axis (X), with a drive and reception device (7) for exciting an oscillation in the oscillating bodies or for detecting an oscillation in the oscillating bodies, with a diaphragm (61) for elastically coupling one of the oscillating bodies (3), and with a clamping device (8) for clamping the drive and/or reception device (7) against the oscillating bodies. The level meter is advantageously characterized by the diaphragm (61), which runs in a lateral direction relative to the longitudinal axis (X) of the outer oscillating body (3) and on the outside passes into a transitional element (5, 51), said transitional element (5) being positioned between the drive and/or reception device and the inner oscillating body for the purpose of transmitting the oscillations between the drive and/or reception device and the inner oscillating body, and said transitional element (5) running in part, with one wall (54), in a lateral direction adjacent to the diaphragm (61); the clamping device, which clamps the diaphragm (61) and the drive and/or reception device in such a way that the drive and/or reception device is clamped against the transitional element; and a gap (s) between the adjacent walls (63, 54) of the diaphragm (61) and of the transitional element (51). The design and dimensions of the gap permit the free oscillation of the diaphragm vis-a-vis the transitional element. At the same time, when strong lateral displacing forces are exerted on the outer oscillating body, the diaphragm will come up against the adjacent wall due to the smaller dimensions of the gap, with the result that a plastic deformation of the diaphragm is avoided. Also prevented is the disengagement of the drive and/or reception device.
