Title (EN) DEVICE AND METHOD FOR MEASURING TEMPERATURE IN SEMI-TRANSPARENT MATERIALS
(FR) DISPOSITIF ET PROCEDE DE MESURE DE LA TEMPERATURE A L'INTERIEUR DE MATERIAUX SEMI-TRANSPARENTS
Abstract:
(EN) A depth pyrometer and its use in determining the temperature in substantially transparent materials are disclosed. A depth pyrometer is made up of assemblies comprising an infrared detector (1), an interference filter (2) and a focusing lens (43) for measuring the monochromatic luminance of beams (FP, FS3) guided by mirrors (6). The pyrometer comprises a switch (4), sighting means (8, 9, 10, 11), and electronic means for processing the signals from the detectors, which may be connected to a computer. The invention applies to temperature measuring methods and devices.
(FR) La présente invention est relative à un pyromètre de profondeur et à son utilisation pour déterminer la température à l'intérieur de matériaux sensiblement transparents. Un pyromètre de profondeur comporte des ensembles composés d'un détecteur infra-rouge (1), d'un filtre interférentiel (2) et d'un objectif de focalisation (43), qui mesurent la luminance monochromatique de faisceaux (FP, FS3) guidés par des miroirs (6). Le pyromètre comporte un commutateur (4), des moyens (8, 9, 10, 11) de visée, et des moyens électroniques de traitement des signaux desdits détecteurs, qui peuvent être connectés à un calculateur. Le domaine technique de l'invention est celui des procédés et dispositifs de mesure de température.
