TRANSMITTER OF PARAMETERS OF ROTATION Russian patent published in 1998 - IPC

FIELD: various branches of industry, determination of angles of turn and rotation velocity. SUBSTANCE: transmitter has two flat rotating electromagnetic screens with slits. Screens are located between immobile flanges with measurement windings and immobile flange with excitation winding. Elements sensitive to variation of magnetic flux are put on flanges with measurement windings. These sensitive elements are manufactured in the form of concentric rings from strips of magnetic film. Strips have through holes. Turns of measurement winding are put through these holes. Strips are installed in rings in staggered arrangement with spacing equal to width of slit in screen. Distance between strips of magnetic film is less than length of strip. EFFECT: capability to measure rotation velocity in wide range of its change with high accuracy and sensitivity. 3 cl, 14 dwg
