Abstract
A gyroscopic measuring apparatus with a mechanical resonator comprises at least four identical, parallel vibrating beams integral with a common base and having the same natural frequency. Each beam supports piezoelectric elements for excitation purposes and for detecting vibration of the beam. The base is cruciform and the beams are disposed respectively at ends of branches of a cross formed by the base.
