Abstract

UN TRANSDUCTOR DEL PAR TORSOR MAGNETOELASTICO PARA MEDIR SIN CONTACTO FISICO, EL PAR TORSOR EN UN EJE ESTACIONARIO O GIRATORIO. EL TRANSDUCTOR COMPRENDE UN EJE (1) CON DEVANADOS DE EXCITACION QUE LO RODEAN (2, 3) Y DEVANADOS DE MEDIDA (10, 11). CONCENTRICAMENTE CON LAS ESPIRAS, SE CREAN ZONAS DE MEDICION ANISOTROPICA MEDIANTE LA APLICACION DE CAPAS (8, 9), POR EJEMPLO EN FORMA DE BANDAS DE COBRE, EN LA SUPERFICIE DEL EJE. EN UNA VERSION PREFERIDA EL ANGULO ENTRE LAS BANDAS Y UNA GENERATRIZ DE LA SUPERFICIE DEL CILINDRO DEL EJE DEL TRANSDUCTOR SE DETERMINA QUE SEA DE (MAS MENOS) 45 (GRADOS) .
