Abstract

L'invention concerne un appareil en vue de mesurer une température sans contact On effectue une mesure de température au moyen d'un pyromètre à radiation 18 disposé dans un logement principal 1 resistant à la pression et comportant des ouvertures d'entrée et de sortie de lignes résistant à la pression. La paroi 2 de ce logement qui est réservée au système optique 18a du pyromètre à radiation 18, comporte une garniture recevant une rondelle de germanium disposée devant le système optique 18a comme fenetre d'entrée de rayons. L'appareil de l'invention est utilisé notamment dans des locaux et des exploitations souterraines afin d'éviter les risques d'explosion et les coups de grisou.The invention relates to an apparatus for measuring a temperature without contact. A temperature measurement is carried out by means of a radiation pyrometer 18 arranged in a pressure-resistant main housing 1 and having inlet and outlet openings for pressure resistant lines. The wall 2 of this housing, which is reserved for the optical system 18a of the radiation pyrometer 18, comprises a lining receiving a germanium washer placed in front of the optical system 18a as a ray entry window. The apparatus of the invention is used in particular in premises and underground operations in order to avoid the risks of explosion and firedamp blasts.
