Abstract

SE PRESENTA UN METODO MEJORADO PARA MEDIR LA DISTANCIA (B) ENTRE DOS SUPERFICIES MUTUAMENTE OPUESTAS (1, 2) POR MEDIO DEL METODO DE LA RELUCTANCIA, SE UTILIZA UN INDICADOR DE POSICION (4) CUYO DISPOSITIVO MEDIDOR (9) ESTA MONTADO SOBRE UN NUCLEO ASOCIADO (10) DISPUESTO SOBRE UNA (1) DE LAS DOS SUPERFICIES. LA OTRA SUPERFICIE (2) ESTA PROVISTA TANTO DE UN IMAN PERMANENTE COMO DE UN ELECTROIMAN (14). CUANDO LAS SUPERFICIES OPUESTAS GIRAN EN RELACION UNA A LA OTRA (R), LA DISTANCIA PUEDE MEDIRSE CON LA AYUDA DE UNA BOBINA CUYA FUERZA ELECTROMOTRIZ INDUCIDA CONSTITUYE UNA MEDIDA DE LA DISTANCIA A MEDIR. UN VALOR DE LA DISTANCIA PUEDE TAMBIEN OBTENERSE CON LA AYUDA DE UN ELEMENTO "HALL" (9), QUE EN LA DETECCION DE UN CAMPO MAGNETICO ESTATICO PRODUCE UN VALOR DE CORRIENTE ELECTRICA QUE CONSTITUYE UNA MEDIDA DE LA DISTANCIA A MEDIR. EL CAMPO MAGNETICO SE EQUILIBRA CON LA AYUDA DE UNA BOBINA (N2) MONTADA SOBRE EL NUCLEO, HACIENDO POSIBLE DE ESTA FORMA QUE PUEDA MEDIRSE LA DISTANCIA MIDIENDO LA CORRIENTE DE AJUSTE SUMINISTRADA POR LA BOBINA EQUILIBRADORA. CUANDO EL DISPOSITIVO MAGNETIZADOR (M) SOBRE LA OTRA SUPERFICIE TIENE LA FORMA DE UN ELECTROIMAN, EL SUMINISTRO DE CORRIENTE AL DISPOSITIVO Y A LA BOBINA EQUILIBRADORA ADICIONAL (N2'') EN EL NUCLEO ES UNA CORRIENTE ALTERNA.
