Abstract

UN EMISOR PARA GENERACION INDUCTIVA DE UNA SEÑAL DE MEDIDA, QUE REPRODUCE LA POSICION RELATIVA DE DOS CUERPOS MOVILES UNO RESPECTO A OTRO, COMPRENDE POR LO MENOS UNA BOBINA DE EXCITACION ALIMENTADA POR CORRIENTE ALTERNA PARA LA PRODUCCION DE UN FLUJO MAGNETICO, UNA DISPOSICION DE BOBINAS DE MEDIDA, EN LAS QUE SE PUEDEN TOMAR TENSIONES, DE LAS QUE SE DERIVA LA SEÑAL DE MEDIDA, Y UN DISPOSITIVO DE CONDUCCION DEL FLUJO HECHO DE MATERIAL FERROMAGNETICO, QUE CONDUCE EL FLUJO MAGNETICO GENERADO POR LA BOBINA DE EXCITACION A UN RECORRIDO DE MEDICION CERRADO EN FORMA DE ANILLO DE TAL MODO QUE AL MENOS UNA PARTE DEL FLUJO MAGNETICO ATRAVIESE LA DISPOSICION DE BOBINAS MAGNETICAS, Y POR LO MENOS UNA DE LAS TENSIONES A TOMAR DE LA DISPOSICION DE BOBINAS SE MODIFIQUE EN FUNCION DEL MOVIMIENTO DE UNO DE LOS DOS CUERPOS RESPECTO AL OTRO. PARA LOGRAR UNA PRECISION DE MEDIDA ESPECIALMENTE ELEVADA Y UNA FIDELIDAD DE LINEAS CARACTERISTICAS, SE FORMA LA SEÑAL DE MEDIDA COMO COCIENTE DE DOS SEÑALES INTERMEDIAS,DE LAS CUALES AL MENOS UNA DEPENDA DE LA POSICION INSTANTANEA DE UNO DE LOS DOS CUERPOS RESPECTO AL OTRO, Y PARA ELLO SE TENDRA CUIDADO DE QUE EN CADA UNA DE LAS SEÑALES INTERMEDIAS ENTREN LAS DIFERENCIAS DE TENSIONES ( ROPORCIONA LA DISPOSICION DE LAS BOBINAS DE MEDIDA (30).
