Abstract
Dans ce procédé on controle la température de la barre, on obtient une représentation électrique d'une correction de décalage par rapport à une température de référence ainsi qu'une représentation électrique d'un facteur de correction de vitesse par rapport à une température de référence et on corrige le signal de sortie du capteur de détection de position de barres en formant une représentation électrique du produit du signal de sortie du capteur et du facteur de correction de vitesse puis en ajoutant à ce produit la correction de décalage précitée.
