PURPOSE:To enable the detection of an angular velocity, by providing an output signal generating means for generating an output signal required in reducing the difference of the value of a vibration number signal and the predetermined number of vibrations and a mean for regulating an actual circumferential temp. to a predetermined circumferential temp. by the association with the output signal. CONSTITUTION:When temp. difference is present between an actual circumferential temp. T and a predetermined circumferential To, an angular velocity sensor 10 is selectively heated to bring said difference to zero and the actual resonance frequencies (f) of both vibrators of the sensor 10 are almost held to predetermined resonance frequencies fo as understood from the drawing. Therefore, the offset amount mixed in the angular velocity signal Vomega from the angular velocity sensor 10 becomes almost constant while the separation of the offset amount from the value of the angular velocity signal Vomega becomes easy and the angular velocity of an object can be calculated as a value with good accuracy. |
