Abstract

Procédé et dispositif pour capteur et comparateur, applicable aux asservissements de position. Le capteur traduit la position d'un organe mobile en rotation ou translation. Il émet en permanence au moins quatre signaux variant périodiquement avec la position du capteur, et déphasés de pi /2 . On compare les signaux qui sont normalement en phase lorsque l'écart entre les deux capteurs est nul et on redresse leur différence à l'aide des signaux situés à plus et moins pi /2. En version pneumatique les capteurs émettent des pressions, le signal de sortie du comparateur est un déplacement de pièce de part et d'autre d'une position 0. Procédé et dispositif utilisables sur les machines comportant des asservissements de position, télé-manipulateurs, positionneurs, machines de chargement, robots industriels, manutention automatique.
