STAND FOR TESTING PRECISION ANGULAR VELOCITY GYROSCOPIC PICKUP Russian patent published in 1995 - IPC

FIELD: measurement technology. SUBSTANCE: gyroscopic pickup is used as sensitive element of the stand as well. The sensitive element has stabilization amplifier, adder, contact-free permanent current engine, and photoelectric moire angle-data transmitter. The gyroscopic pickup tested is connected with stand elements during period of testing into two-circuit engine control system. Output of feedback amplifier is connected with the first input of the adder, which has the second input to be connected with reference voltage set-point device. Output of the adder is connected with the first input of stabilization amplifier. The first to the third outputs of the amplifier are connected with the first to the third inputs of permanent current engine. The first and the second outputs of the engine are connected with the second and the third outputs of stabilization amplifier. EFFECT: improved precision of measurement. 2 dwg
