Abstract

UN DISPOSITIVO PARA LA MEDICION DE UN FLUJO DE CORRIENTE EN UN CIRCUITO DE CONEXION ABARCA UN OSCILADOR (1) CON UNA BOBINA (2) ACOPLADA. EL CIRCUITO DE CONEXION ABARCA UN CABLEADO (4) DE CONTORNO, TRAMOS (5) SEMICONDUCTORES, PISTAS CONDUCTORAS Y PATAS DE CONEXION DEL CIRCUITO INTERRUPTOR. LA PATA DE CONEXION IC A SER MEDIDA ESTA UNIDA CON UN LADO DE UN RECTIFICADOR/AMPLIFICADOR (6) SELECTIVO Y UN LADO DE UN ESTRANGULADOR (7). EN EL OTRO LADO DEL RECTIFICADOR/AMPLIFICADOR (6) SE CONECTA UN VOLTIMETRO (8). EL ESTRANGULADOR HACE CONTACTO EN UNA FUENTE (9) DE TENSION PROGRAMABLE. EL CIRCUITO (3) INTERRUPTOR SE COLOCA CON UNA TENSION AUXILIAR, QUE ABRE EL DIODO (5) EN EL CIRCUITO INTERRUPTOR. LA BOBINA SE GUIA A TRAVES DEL CIRCUITO INTERRUPTOR A SER MEDIDO E INDUCE LOCALMENTE UN CAMPO MAGNETICO DE ALTA FRECUENCIA, QUE MODULA LA CORRIENTE CONTINUA QUE FLUYE A TRAVES DEL DIODO. A PARTIR DEL GRADO DE MODULACION PUEDE SER CERRADA LA CORRIENTE QUE FLUYE SOBRE LA MAGNITUD CORRESPONDIENTE.
