Patent ID: 7980134

Claim:
A measuring device for determining a measured quantity, comprising: an oscillatory structure in which an oscillation signal is detectable; an exciter configured to excite the oscillatory structure by an excitation frequency to result in an oscillation with an oscillation frequency; a processor configured to process the oscillation signal synchronous to the oscillation frequency or the excitation frequency; and an evaluator configured to determine the measured quantity based on the processed oscillation signal, wherein the oscillatory structure comprises a mechanical structure capable of oscillating in a first oscillation mode and a second oscillation mode which comprise a coupling depending on the measured quantity, wherein the oscillatory structure is excitable to result in an oscillation in the first oscillation mode by an excitation by the exciter at the excitation frequency, and the oscillatory structure is coupled to the processor such that a signal resulting from the oscillation of the mechanical structure in the second oscillation mode is available for the processor as a detectable oscillation signal.
