Abstract
La présente invention concerne un dispositif pour la mesure de la température. Le dispositif comporte un élément thermosensible en forme d'un prisme en verre 1, dont les deux faces opposées latérales 3 et 4 sont disposées par rapport à sa base 5 sous un angle ** - de réflexion intérieure complete de verre à partir duquel le prisme 1 est fabriqué et le liquide 2 où on l'a dispose. L'indice de réfraction du liquide 2 diminue d'une façon monotone avec l'augmentation de la température. La base du prisme 1 est reliee par un conduit de lumière fibreux 10, 11 à une source 7 de lumière et à un photorécepteur 8 de l'appareil de mesure 9. Application : la mesure de la température des enroulements des transformateurs à haute tension des électromoteurs de grande puissance; réacteurs chimiques contenant un milieu corrosif.
