Abstract
DISPOSICION PARA LA DETECCION DE LA EXISTENCIA Y/O PARA LA DETERMINACION DE LA FORMA DE PEQUEÑAS CANTIDADES DE UNA SUSTANCIA MAGNETICA. LA DISPOSICION CONTIENE UN SENSOR (1) QUE TRABAJA SEGUN EL PRINCIPIO DE SATURACION DEL NUCLEO, QUE PRESENTA UN CIRCUITO MAGNETICO (2; 3) ASI COMO, AL MENOS, BOBINAS (4, 5). LA SUSTANCIA MAGNETICA ES P.EJ. UNA TINTA MAGNETICA DE UN BILLETE DE BANCO (11). EL CIRCUITO MAGNETICO (2; 3) CONSTA DE AL MENOS UN ENTREHIERRO (2) Y UN NUCLEO (3) FERROMAGNETICO. LA SUSTANCIA MAGNETICA SE ENCUENTRA EN EL ENTREHIERRO (2). EL SENSOR (1) ES UN SENSOR PARA LA MEDICION DE LA PERMEABILIDAD ((MU)R*) RELATIVA EFECTIVA DEL CIRCUITO MAGNETICO (2;3). UN GENERADOR (6) ALIMENTA UNA DE LAS DOS BOBINAS (4;5) MEDIANTE UNA RESISTENCIA EN SERIE (7) CON UNA CORRIENTE DE EXCITACION (I[T]-) VARIABLE PERIODICAMENTE. UNA TENSION DE SALIDA (U[T]) DEL SENSOR (1) ESTA DIRIGIDA PARA LA EVALUACION DE UNA ONDA SUPERIOR DEL MISMO A UNA ENTRADA DE UNA DISPOSICION (8), QUE CONSTA DE UN CIRCUITO EN CASCADA DE UN AMPLIFICADOR DE FILTRO PASABANDA (9) Y UN VOLTIMETRO (10). LA DISPOSICION NO NECESITA IMANES PERMANENTES, TAMPOCO BLINDAJE MAGNETICO Y PERMITE UNA MEDICION ESTATICA.
