Abstract

Dispositif pour la signalisation de l'état d'un appareil pouvant prendre plusieurs états discrets et la transmission de l'information correspondante, caractérisé en ce qu'il comprend un dispositif pour élaborer, à l'intérieur d'une enceinte blindée, une tension continue exempte de perturbations. L'enceinte blindée comporte à son intérieur un premier dispositif pour élaborer, à partir de la tension continue, des impulsions électriques de durée proportionnelle à la valeur d'une inductance, cette inductance pouvant prendre des valeurs distinctes selon les divers états de l'appareil, et un second dispositif pour convertir les impulsions électriques en impusions optiques et une fibre optique pour transmettre ces impulsions hors de l'enceinte vers un centre de traitement.
