Abstract

CONVERTIDOR DE MEDICION QUE COMPENSE AUTOMATICAMENTE LA INFLUENCIA DE CAMPOS MAGNETICOS EXTRAÑOS. CONSTA DE UN CONDUCTOR PLANO (1) PORTADOR DE LA CORRIENTE DE MEDICION (1) Y DOS PERCEPTORES DE CAMPO MAGNETICO (2, 3) QUE MIDEN EL DEL CONDUCTOR PLANO (1) PROPORCIONAL A LA CORRIENTE (1). EL CAMPO EXTERIOR EN EL PUNTO DE MEDICION DE UNO DE LOS PERCEPTORES MAGNETICOS (2) ESTA DIRIGIDO EN SENTIDO OPUESTO AL MEDIDO EN EL OTRO PERCEPTOR (3). UN CIRCUITO DE MEDICION (4) FORMA UNA SEÑAL DE SALIDA A PARTIR DE LAS SEÑALES (U , U ) DE LOS DOS PERCEPTORES DE CAMPO MAGNETICO (2, 3), SIENDO ESTA SEÑAL DE SALIDA INDEPENDIENTE DE CAMPOS EXTRAÑOS (HE).
