Abstract

TRANSDUCTOR ELECTROMAGNETICO DE RELUCTANCIA VARIABLE. COMPRENDE UNA FUENTE DE FLUJO MAGNETICO (11) Y UN ARROLLAMIENTO CAPTADOR (14) UNIDO A DICHA FUENTE CON EL FIN DE PRODUCIR SEÑALES DE SALIDA EN RESPUESTA AL MOVIMIENTO DE UN ELEMENTO (16) DE MATERIAL MAGNETICO. EL BORDE DE DICHO ELEMENTO (16) ESTA CONFORMADO DE FORMA QUE LA RELUCTANCIA DEL CIRCUITO CAMBIE CUANDO EL ENTREHIERRO SEA PUNTEADO POR UN DIENTE O SALIENTE DEL ELEMENTO MOVIBLE (16). UN CIRCUITO DISCRIMINADOR, OTRO DE POLARIZACION Y UN COMPARADOR DE VOLTAJE COMPLETAN EL DISPOSITIVO.
