Control system and apparatus for controlling current input to an electrical resistance element such as a seal wire. The system and apparatus of the present invention is a closed loop feedback modification to conventional systems, and takes advantage of the inherent expansion of the seal wire as it is heated. The feedback mechanism monitors both the actual current passing through the wire, and the length of the sealing wire, and adjusts the current applied to the wire, responsive to those monitored inputs. The usage of the sealing machine is also monitored and the application and amount of current flowing to the wire is varied based on this usage.
L'invention concerne un système et un appareil de commande permettant de commander l'entrée de courant dans un élément résistance électrique tel qu'un fil de scellement. Le système et l'appareil de la présente invention sont une modification <= rétroaction en boucle fermée >= des systèmes conventionnels, et tirent profit de l'expansion inhérente au fil de scellement lorsque ce fil est chauffé. Le mécanisme de rétroaction surveille à la fois le courant actuel circulant dans le fil de scellement et la longueur de ce dernier, et ajuste le courant appliqué au fil, en réaction aux entrées surveillées. L'utilisation de la machine à sceller est également surveillée et l'application et la quantité de courant s'écoulant dans le fil varient en fonction de son utilisation.
