FIELD: measurement technology; vibration Corolis gyroscopic angular-rate sensors.
SUBSTANCE: proposed method consists in simultaneous excitation of self-excited oscillations of the first and second (orthogonal) modes at stabilization of oscillation rate amplitude; phase of exciting forces at linear oscillations or moments at angular oscillations corresponds to phase of signal proportional to sum of oscillation rates in the first mode and in the second (orthogonal) mode; output signal is so formed that it is proportional to difference of amplitudes of exciting forces or moments. Device proposed for realization of this method has reference signal source, two self-excited oscillation excitation circuit, adder combining outputs of both excitation circuits and differential amplifier which is used as output of device.
EFFECT: enhanced accuracy.
