INDUCTION SENSOR OF ANGULAR POSITION Russian patent published in 2018 - IPC G01B7/30 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment and can be used to measure angular displacements by a displacement transducer of induction type. Essence of the invention consists in that the induction sensor of angular position comprises a rotating transformer and fixed and movable flat plates of a dielectric material, mounted with a common rotation axis relative to each other with one degree of freedom, facing each other sides with printed flat zigzag inductors, wherein the sensor comprises one pair of movable and fixed plates, the movable plate contains two identical inductors, which are evenly distributed in equal sectors with an opening angle of 180°, the fixed plate contains two pairs of inductors with an opening angle of 180°, and shifted relative to one other by an angle of 90°, the active long conductors of the two pairs of inductors are nested inside each other through the turn along the radius.

EFFECT: invention makes it possible to simplify the sensor design, to reduce the overall dimensions, to increase its reliability and reduce cost of the sensor.
