Abstract

DISPOSICION DE CONEXIONES PARA EL FUNCIONAMIENTO DE UN SENSOR MAGNETOELASTICO, QUE ELIMINA SENSIBLEMENTE LA DEPENDENCIA DE LA SEÑAL DEL SENSOR (34) DE LA DISTANCIA COMPRENDIDA ENTRE LA BOBINA DEL SENSOR (16) Y EL OBJETO DE MEDIDA (10). LA BOBINA DEL SENSOR (16) SE COMPLETA CON UN CONDENSADOR (30) Y CON UNA RESISTENCIA DE AMORTIGUADO (32) PARA FORMAR UN CIRCUITO OSCILATORIO CON AMORTIGUADO AJUSTABLE. MEDIANTE LA ELECCION ADECUADA DEL VALOR DE LA RESISTENCIA DE AMORTIGUADO (32), DE LA INDUCTIVIDAD DE LA BOBINA DEL SENSOR (16), DE LA CAPACIDAD DEL CONDENSADOR (30) ASI COMO DE LA FRECUENCIA (F) DE LA FUENTE DE ENERGIA DE TENSION ALTERNA (20) NECESARIA PARA EL FUNCIONAMIENTO PUEDE AJUSTARSE LA DISPOSICION DE CONEXIONES DE TAL FORMA QUE LA DISTANCIA (14) COMPRENDIDA ENTRE LA BOBINA DEL SENSOR (16) Y EL OBJETO DE MEDIDA (10) NO TENGA YA PRACTICAMENTE NINGUN EFECTO SOBRE LA SEÑAL DEL SENSOR (34). LA DISPOSICION DE CONEXIONES SEGUN LA INVENCION SIMPLIFICA EL EMPLEO DE UN SENSOR MAGNETOELASTICO ESPECIALMENTE EN LA DETECCION DEL ESTADO DE TENSION DE UN OBJETO DE MEDIDA DESPLAZADO (10).
