Abstract
A vibration detector for determining and/or monitoring a predetermined fill level in a container. The detector includes an oscillatable unit, a driver/receiver unit and an evaluation unit. The vibration detector can, additionally, be used as a viscosity sensor or as a density sensor. For providing a multivariable sensor, a microprocessor is provided in the oscillation circuit formed of oscillatable unit and feedback electronics. The microprocessor corrects the phase of the feedback electronics over a predetermined frequency bandwidth in such a way that the sum of the phases of the feedback electronics and the microprocessor follows a predetermined function f(v).
