Abstract

Abstract Translated from French @ L'invention concerne un procédé et un appareil de réglage d'un déviateur sans l'usage d'un tube d'essai. @ The invention relates to a method and an apparatus for adjusting a diverter without the use of a test tube. On utilise une tête de mesure qui échantillonne le champ le long de l'axe du déviateur en au moins deux zones. Les signaux issus de la tête de mesure mesurant les champs engendrés par les bobinages de ligne et de trame sont fournis à un calculateur (31) qui simule les opérations de réglage mécanique. Le signal d'erreur fourni à un asservissement permet de commander des moteurs de déplacement de la trame (24) par rapport à la ligne (26). A measuring head is used which samples the field along the axis of the deflector in at least two zones. The signals from the measuring head measuring the fields generated by the line and frame windings are supplied to a computer (31) which simulates the mechanical adjustment operations. The error signal supplied to a servo enables the motors for moving the frame (24) relative to the line (26) to be controlled.
