TWO-CHANNEL ANGULAR SPEED SENSOR Russian patent published in 2020 - IPC G01C19/02 

FIELD: gyroscopic instrument making.

SUBSTANCE: angular velocity two-channel sensor is based on a gyroscope with a spherical bearing. Stators of inductive-type angles sensors are fixed on the base, two stators per each measurement axis and stators of electromagnetic-type sensors of two types per each control channel. Rotor is a ferrite ring mounted in the gyromotor rotor. To measure angular velocities coinciding in direction with axes of arrangement of force sensors, signals of angular sensors, passing differential adders and coordinate converters, are brought to axes of force sensors. For each control channel, these signals for one force sensor are summed up with the reference voltage source signal, and for the other one are subtracted. Force transducers moment is balanced by gyro at each channel, and output signal is generated by measuring currents in each force sensor in the form of voltages taken from scale resistors included in force transducer circuits and supplied to output summing amplifiers.

EFFECT: simple design of a two-channel angular velocity sensor without loss of measurement accuracy.
