Abstract

L'invention a trait à un procédé permettant de commander la température existant dans des dispositifs d'étanchéité utilisés dans l'industrie du conditionnement. Ces dispositifs sont pourvus d'éléments chauffés électriquement et faits d'un matériau dont la résistance est fonction de la température. Le courant électrique est divisé en impulsions dont la longueur est adaptée à l'aide d'un commutateur commandé (6). Pendant les interruptions intervenant entre ces impulsions de courant, des impulsions distinctes de courant de mesure d'une valeur connue et constante sont produites, entraînant une chute de tension électrique sur l'élément à résistance (2). Cette chute de tension, qui est proportionnelle à la température de l'élément à résistance, est alors comparée dans un régulateur (7) à un potentiel fixé correspondant à une température souhaitée. De la sorte, la différence de potentiel obtenue par détection entre la chute de tension mesurée et la valeur de potentiel fixé est ajustée afin d'agir sur un dispositif de commande (9) qui règle la longueur des impulsions de courant calogène.
