Abstract

Ce dispositif comprend un circuit oscillant électrique comportant une bobine induction 20 dans le champ de laquelle se déplace l'objet à détecter. Cette bobine est connectée à un circuit comprenant un moyen 100 de synchronisation dont les signaux de sortie sont appliqués à un moyen 102 de commande Ce dernier interrompt périodiquement le circuit de la bobine de manière à lui donner des impulsions de fréquence prédéterminée. Les ondes amorties produites, caractéristiques de l'objet à détecter, sont recueillies la sortie de la bobine et envoyées dans un détecteur 104 sensible à la forme des ondes amorties. Un compteur 106 compte les périodes de l'onde amortie qui dépassent une tension prédéterminée. Les comptes établis par le compteur sont ensuite envoyés à deux moyens de blocage 110 et 112 par l'intermédiaire d'un décodeur 108. Applications, notamment aux distributeurs automatiques et aux machines analogues qui reçoivent des pièces de monnaie ou des jetons.
