Abstract

Procédé d'identification d'objets, dans lequel les objets marqués par une bande magnétique passent dans un champ magnétique alternatif et engendrent un déséquilibre dans une bobine détectrice; le signal est appliqué à un dispositif de détection. On utilise un échantillonnage de bandes en alliages à cycles d'hystérésis différents; on attribue une valeur de code à chaque type d'alliage; on détecte par mesure du décalage de phase du signal par rapport au champ d'excitation. L'invention s'applique à l'identification de chaque échantillon en traitement dans une machine de traitement en continu
