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

FIELD: physics.

SUBSTANCE: device has two transformer angle sensors. The output of each sensor is connected to series-connected differential amplifier, storage sampling device, analogue-to-digital converter and register. The outputs of the registers are connected to inputs of an adder. The output of the adder is connected to a data register. Outputs of the control unit are connected to second inputs of the storage sampling devices, analogue-to-digital converters, registers, adder and data register.

EFFECT: higher measurement accuracy owing to reduced errors caused by offset of the rotation axis of conversion of the device for measuring angular displacements, less requirements for accuracy of actuation and rigidity of mechanical assemblies.
