A bell-like high-Q member for detecting motion of a platform about an axis and having a lip capable of sustaining therein a vibration pattern having alternately and equi-angularly spaced nodal and anti-nodal regions of radial vibration when the lip is exercised radially. Pickoff electrodes located at regions nodal in the absence of rotation about the axis detect radial vibrations developed thereat due to the effects on the vibrations pattern of the rotation about the axis. Forcer electrodes located at other regions nodal in the absence of rotation are connected in circuit with the pickoff electrodes to null such radial vibrations.
