ABSTRACT:
An angular velocity sensor is provided with a spherical liquid inertia mass, preferably mercury, which can rotate with respect to a vessel in which it is contained. A magnetic field passes through the inertial mass and the electrode pairs. One electrode of each pair of electrodes between which a voltage is measured is located in the center and the other near the wall of the spherical mass and/or in which the direction of the magnetic field is invariable in space.
