Abstract
_(APARATO PARA DETECTAR LA PRESENCIA, DENTRO DE UNA ZONA DE VIGILANCIA, DE UN CUERPO DE MATERIAL DE ALTA PERMEABILIDAD . CONSTA DE UNA SERIE DE CANALES DE FILTRO EN PARALELO QUE SELECCIONAN LAS COMPONENTES DE SEGUNDA Y TERCERA ARMONICA DE LAS PERTURBACIONES CREADAS POR EL MATERIAL DE ALTA PERMEABILIDAD CUANDO ESTA PRESENTE EN EL CAMPO. SE COMPARA LA FASE DE LA SEGUNDA ARMONICA CON UNA SEÑAL DE REFERENCIA. EL NIVEL DE SEÑAL DE CADA UNO DE LOS COMPONENTES DE SEGUNDA Y TERCERA ARMONICA, ASI COMO LA CONGRUENCIA DE FASES CONTROLAN EN COOPERACION UN CIRCUITO DE ALARMA. UNAS BOBINAS TRANSMISORAS DE FORMA DE ROMBOIDE QUE RODEAN A BOBINAS RECEPTORAS EN FORMA DE OCHO, MEJORAN EL ACOPLAMIENTO CON EL CUERPO DE ALTA PERMEABILIDAD.
