Abstract

EL SENSOR (1) FUNCIONA DETECTANDO LA VARIACIONES EN EL CAMPO MAGNETICO INDUCIDO EN UN ESPACIO (4) POR ACUMULACION GRADUAL EN EL MISMO DE PARTICULAS FERROMAGNETICAS (P) SUSPENDIDAS EN UN FLUIDO (F). EL CIRCUITO MAGNETICO QUE INCLUYE EL INTERSTICIO ESTA POLARIZADO POR UN IMAN PERMANENTE (3). UNAS BOBINAS DE INDUCCION ELECTRICA (7) ASOCIADAS CON UN CIRCUITO MAGNETICO AUXILIAR PERMITEN QUE UN CAMPO MAGNETICO OPUESTO AL GENERADO POR EL IMAN PERMANENTE (3) SE PRODUZCA HASTA QUE EL CAMPO MAGNETICO EN EL INTERSTICIO QUEDA ANULADO. ESTO PROVOCA LA SEPARACION DE LAS PARTICULAS (P) ACUMULADAS EN LA PROXIMIDAD DE DICHO INTERSTICIO, LIMPIANDO O REGENERANDO ASI EL SENSOR.
