ABSTRACT:
A rotary speed sensor including an oscillator that can be excited to oscillate in a first direction (X direction). Upon a rotation about the Z axis, Coriolis forces in a second direction (Y direction) occur on the oscillator. The Coriolis forces are transmitted by oscillator springs to a detection element, where they can be detected from the deflection of movable electrodes.
