FIELD: physics.
SUBSTANCE: invention relates to vibration-type micromechanical gyroscopes (MMG), in particular to a device for measuring a gap between the fixed electrodes and the moving weight (MW). Device for measuring a gap between the fixed electrodes of the secondary oscillations channel and the MW in a micromechanical gyroscope of the RR-type includes a MW, a differential capacitive sensor formed by two fixed electrodes arranged along the axis of secondary oscillations and a the MW, two capacitance-to-voltage (code) converters, whose inputs are connected to the corresponding electrodes of the capacitive sensor, and an additionally introduced computing device implementing the function of 
, whose inputs are connected to the outputs of the first and the second capacitance-to-voltage (code) converters, where V1, V2 are signals at the output of the first and the second capacitance-to-voltage (code) converters, respectively.
EFFECT: technical result is an increase in the accuracy of the MMG operation in harsh conditions.
