FIELD: measurement equipment.
SUBSTANCE: angular speed meter comprises two micromechanical gyroscopes (MMG), an accelerometer and a signal conversion device. The signal conversion device comprises a signal switchboard and a spectrum analyser, the input of which is connected to the accelerometers output. The inputs of the signal switchboard are connected to the outputs of the first and second MMG, and the output of the switchboard is an output of the angular speed measurement device, the spectrum analyser output is connected with the control input of the switchboard. Both MMG are related to gyroscopes of RR-type, and difference of their resonant suspension frequencies along the axis of primary oscillations makes at least 10% of the resonant frequency of one of them.
EFFECT: higher accuracy and reliability under action of considerable vibration effects.
