Abstract
L'invention concerne un appareil pour maintenir une première partie et une seconde partie d'un élément chauffant électrique à des températures prédéterminées. Un appareil selon l'invention est caractérisé par un transformateur de courant dont le primaire 13 est réglé par un régulateur de température 12 commandé par un détecteur de température 17 détectant la température d'une première partie 18 d'un élément chauffant électrique 24 dont la température est détectée par un détecteur 16 connecté à un second régulateur de température 1 qui commande des dispositifs à thyristors 62 et 63 de façon à régler dans les deux parties 18 et 19 le courant de façon telle que ces parties soient maintenues à des températures prédéterminées. Un appareil selon l'invention convient en particulier pour régler les températures des deux parties d'une tête de filière utilisée pour la production de fibres de verre.
