Abstract

Procédé de mise en oeuvre d'un dispositif de filtre magnétique comprenant une masse filtrante traversée par un courant d'un fluide contenant des composants à sensibilité magnétique que l'on désire séparer du fluide en appliquant un champ magnétique à fort gradient de champ cette masse pour recueillir lesdits composants à l'intérieur de la masse L'inductance de ladite masse se modifiant à mesure qu'elle recueille magnétiquement lesdits composants dudit courant de fluide, on surveille le changement d'inductance de ladite masse filtrante à mesure que s'effectue le rassemblement magnétique desdits composants, et on engendre un signal électrique quand l'inductance dépasse une valeur prédéterminée. On produit en outre automatiquement une alarme alertant un opérateur avec ledit signal électrique.
