MAGNETOELECTRIC DISPLACEMENT SENSOR OF A MOVING PIECE, AND DETECTION SYSTEM PROVIDED WITH SUCH A SENSOR

摘要

P THE INVENTION RELATES TO MAGNETOELECTRIC SENSORS FOR MOVING A MOBILE PIECE. / P P THESE SENSORS USUALLY INCLUDE A MAGNETIC CIRCUIT 1, IN FRONT OF THE POLAR FACES 4, 5 WHICH IS MOVING A PERMANENT MAGNET 14 RELATED TO THE MOBILE PIECE, AND ELECTRIC WINDINGS TO THE TERMINALS FROM WHICH THE INDUCED VOLTAGES ARE COLLECTED. FOLLOWING THE INVENTION, THE WINDINGS ARE REDUCED TO TWO SPIERS MADE BY DECOUPAGE OF THE SUPPORT PLATE 22 OF THE MAGNETIC CIRCUIT 1, AND CONNECTED IN PARALLEL TO TERMINALS 8 AND 9. / P P THE APPLICATIONS ARE IN PARTICULAR THE MEASUREMENT SEVERE ENVIRONMENTAL DISPLACEMENT, SUCH AS ROTATION SPEED OF AIRCRAFT REACTORS. / P
