RESONANT MEASURING METHOD OF ROTATION FREQUENCY OF OBJECT AND DEVICE IMPLEMENTING THIS METHOD Russian patent published in 2015 - IPC G01P3/36 

FIELD: measurement equipment.

SUBSTANCE: invention relates to accurate instrument building and can be used at creation of such measuring devices of angular rotation frequency of objects as gyroscopes. According to the resonant measuring method of the object rotation frequency, the measured rotation frequency is determined as difference between proper rotation frequency of the cavity on the chosen type of electromagnetic oscillation and proper frequency of the fixed cavity on the same type of oscillation, which is divided by a constant number determined by the type oscillation chosen at calculation of the cavity, and rotation direction is determined by the sign of the same difference. The device implementing the resonant measuring method of object rotation frequency includes a monochromic active oscillator of retuned frequency, a probe-exciter, an electromagnetic field detector, a device for retuning of frequency of the active oscillator, a frequency meter and a resolver that calculates rotation frequency as difference between resonant rotation frequency of the cavity and resonant frequency of the fixed cavity, which is divided by a constant number determined by the type of electromagnetic oscillation chosen at calculation of the cavity, and direction of rotation is determined by the sign of the same difference.

EFFECT: improving efficiency of the method.
