Abstract

Appareil de commutation électronique à potentiomètre rotatif. Appareil caractérisé par un potentiomètre à double piste et l'utilisation de plusieurs comparateurs effectuant les comparaisons entre les tensions de mesure, d'enclenchement et de déclenchement, comparateur dont les sorties sont reliées à un circuit logique pour n'émettre un signal de commande que lorsque la tension de mesure atteint la tension d'enclenchement et ensuite seulement lorsqu'elle atteint la tension de déclenchement. Applications : émission d'un signal de commande pour certaines positions angulaires de pieces pivotantes, par exemple sur machines-outils.
