Abstract

EN UN TRANSMISOR INDUCTIVO DE POSICION (50) CON UN BOBINA DE EXCITACION (53), UNA DISPOSICION DE BOBINA DE MEDICION (52) Y UN DISPOSITIVO DE CONDUCCION DE FLUJO (51,51) DE MATERIAL FERROMAGNETICO, QUE PREFIJA EL RECORRIDO CERRADO CON FORMA ANULAR (RECORRIDO DE MEDICION) PARA EL FLUJO MAGNETICO GENERADO POR LA BOBINA DE EXCITACION, QUE COMPRENDE AL MENOS UN RESQUICIO, EN CUYO AREA ESTA POSICIONADA LA DISPOSICION DE BOBINA DE MEDICION DE MODO QUE EL FLUJO MAGNETICO IMPUESTO SE MODIFICA EN FUNCION DE LA POSICION A SUPERVISAR, ESTA PREVISTO PARA LA MEJORA DE LA FIDELIDAD DE LINEAS CARACTERISTICAS Y PARA EL AUMENTO DE LA EXACTITUD DE MEDICION DE MODO QUE EL DISPOSITIVO DE CONDUCCION DE FLUJO PARA EL FLUJO MAGNETICO GENERADO POR LA BOBINA DE EXCITACION PREFIJA AL MENOS UN SEGUNDO RECORRIDO CERRADO EN FORMA ANULAR (RECORRIDO DE COMPENSACION) QUE PASA A LA DISPOSICION DE LA BOBINA DE MEDICION EL FLUJO MAGNETICO QUE PASA A TRAVES DE EL. SI EXISTEN DOS BOBINAS DE MEDICION (54,55) DISPUESTAS VECINAS,CUYAS SUPERFICIES PUEDAN SER ATRAVESADAS POR EL FLUJO DE MEDICION DE FORMA VARIABLE Y CUYA DIFERENCIA DE SEÑALES DE SALIDA FORMA PARTE DE LA SEÑAL DE POSICION, ESTA ADEMAS PREVISTO QUE LAS SUPERFICIES CERRADAS POR LAS BOBINAS DE MEDICION AL MENOS PRESENTEN UNA PIEZA MARGINAL COMUN, A TRAVES DE LA CUAL SE PUEDE DESPLAZAR EL FLUJO DE MEDICION.
