Abstract

L'invention concerne un dispositif (0) pour mesurer la position d'une tige de commande coulissante, comportant une pluralité de bobines secondaires (S'1 - S'47) excitées par induction par au moins une bobine primaire (1), disposées les unes derrière les autres le long d'une voie de coulissage, respectivement une ou plusieurs bobines secondaires (S'1 - S'47) étant combinées de telle manière sous forme d'au moins deux groupes de bobines, qu'un signal de position (Ρ'1 - Ρ'3) produit à l'aide du groupe de bobines respectifs augmente ou diminue graduellement lorsque la tige de commande est déplacée le long des bobines secondaires (S'1 - S'47). Un tel dispositif (0) doit d'une part requérir un nombre le plus faible possible de lignes de mesure (M0, Μ1 -Μ'3) et permettre de déterminer d'autre part la position de la tige de commande avec une résolution élevée, à un niveau de sécurité et de fiabilité de fonctionnement élevé. A cet effet, l'agencement et l'interconnexion des bobines secondaires (S'1-S'47) selon l'invention sont choisis de telle sorte que sur la base de tous les signaux de position (Ρ'1-Ρ'3) de tous les groupes de bobines, une détermination univoque de la position instantanée de la tige de commande est possible, et au moins l'un des groupes de bobines comporte au moins deux bobines secondaires (S'1-S'47) qui sont interconnectées de telle sorte que le signal de position correspondant (Ρ'1-Ρ'3) adopte au moins trois niveaux de signal discrets (Ν'0-Ν'3) lors du déplacement de la tige de commande. La présente invention concerne également un procédé correspondant.
