Abstract

a. Appareillage pour régler la durée d'un processus dont le déroulement dépend de la température. b. Un pyromètre 1 repère la température d'un moule M de fonderie. Il délivre une tension électrique en fonction de cette température à un comparateur 2. Celui-ci compare cette tension à une tension de référence, représentative d'une température de consigne, fournie par une ligne 3. Le signal de sortie du comparateur 2, qui est proportionnel à l'écart des tensions et donc des températures, ferme, par l'intermédiaire d'un comparateur 4 et des relais 5, un interrupteur 6 d'un circuit d'alimentation d'un moteur 7 synchrone. c. Moule de fonderie.
