DEVICE FOR MEASUREMENT OF ANGULAR DISPLACEMENTS Russian patent published in 2010 - IPC G01B7/30 

FIELD: physics.

SUBSTANCE: device comprises sinusoid generator, transformer angle detector, differential amplifier, device of selection-storage, analog-digital converter, data register, unit of control and synchronisation, compensation circuit. Inlet of compensation circuit is connected to outlet of sinusoid generator. Coefficient of compensation circuit transfer is set so that voltage at its outlet equals error ΔU_ssd for measurement of outlet voltage of transformer angle detector at the outlet of selection-storage device as outlet voltage of sinusoid generator changes. Voltage that equals ΔU_ssd in value and opposite to it in sign is sent to summator inlet of selection-storage device amplifier.

EFFECT: increased accuracy of angle measurement.
