Abstract

SE SUMINISTRA UN DETECTOR DE APAGONES PARA UN CARRETE SUPERCONDUCTOR EL CUAL UTILIZA UN ACOPLADOR OPTICO Y UN CODIFICADOR GIRATORIO. LA PRESENCIA DE UNA CORRIENTE DE RESISTENCIA EN EL CARRETE SUPERCONDUCTOR CREADA POR UN APAGON HARA QUE SE MUEVA UN CARRETE GIRATORIO DE LECTURA. ESTE MOVIMIENTO SERA DETECTADO MEDIANTE LUZ PASANDO A TRAVES O REFLEJADA POR UN CODIFICADOR OPTICO, QUE INTERRUMPIRA O TRANSMITIRA LUZ PASANDO DE UNA O MAS FUENTES DE LUZ HACIA UNO O MAS SENSORES DE LUZ. OTRAS SINTESIS PREFERIDAS UTILIZAN FIBRAS OPTICAS PARA LAS FUENTES DE LUZ Y LOS SENSORES QUE NO SON AFECTADOS POR CAMPOS MAGNETICOS ALTOS O UN MEDIO AMBIENTE HOSTIL DEL CARRETE SUPERCONDUCTOR
