METHOD FOR MEASUREMENT OF ALTERNATING VOLTAGE AMPLITUDE OF SIGNAL COMING FROM ALARM SENSOR OF GAS CENTRIFUGE ROTATION, WITH APPLICATION OF THIS SIGNAL FREQUENCY METRE Russian patent published in 2010 - IPC G01R29/04

Abstract RU 2383028 C2

FIELD: measurement equipment.

SUBSTANCE: invention is related to separation of isotopes with centrifugal method and may be used in separating enterprises of nuclear industry. According to invention, in method for measurement of alternating voltage amplitude of signal coming from alarm sensor of gas centrifuge rotor rotation, with application of this signal frequency metre, measurement of frequency is carried out by time of fixed voltage crossing with signal. It makes it possible to calculate speed of gas centrifuge rotor rotation and amplitude of alternating voltage of signal coming from specified detector, in one cycle of measurement without application of analog-digital conversion.

EFFECT: monitoring of specified amplitude makes it possible to timely detect wear of support needle in gas centrifuge rotor and/or rise of specified rotor temperature.
