Abstract

L'invention concerne les procédés et dispositifs de contrôle automatique de la production. Le procédé faisant l'objet de l'invention est du type consistant à placer les pièces dans un champ magnétique alternatif dont le vecteur d'inducdion est dirigé perpendiculairement au plan d'asymétrie des pièces, et est caractérisé en ce que les pièces sont disposées dans ledit champ de manière à assurer une répartition homogène de la densité de ce dernier des deux côtés asymétriques de la pièce, l'indice utilisé pour effectuer le triage étant l'effort plus ou moins grand avec lequel la pièce, sous l'action des forces électrodynamiques F 1 , F2 , adhère à un élément ferromagnétique 3, 3' se trouvant dans le champ magnétique. L'invention peut être utilisée notamment pour le contrôle actif de pièces asymétriques de formes et dimensions variées, dans la construction des appareils de mesure, dans l'industrie électrotechnique et radiotechnique.
