Abstract
(EN)
The objective of the present invention is to provide a technology capable of measuring accurately and in a non-contact manner the temperature of a gas, in particular the temperature of a gas containing water vapor. A spectroscopic unit 10 acquires from radiated light from water vapor, at least a light intensity in a first wavelength band and a light intensity in a second wavelength band. The first wavelength band and the second wavelength band are both near-infrared region bands. In addition, the central wavelength of the first wavelength band and the central wavelength of the second wavelength band have mutually different values. A temperature calculating unit 20 is configured to calculate the temperature of the water vapor using the ratio between the light intensity in the first wavelength band and the light intensity in the second wavelength band.

L'objectif de la présente invention est de fournir une technologie apte à mesurer avec précision et d'une manière sans contact la température d'un gaz, en particulier la température d'un gaz contenant de la vapeur d'eau. Une unité spectroscopique 10 acquiert, à partir d'une lumière rayonnée par de la vapeur d'eau, au moins une intensité de lumière dans une première plage de longueurs d'onde et une intensité de lumière dans une seconde plage de longueurs d'onde. La première plage de longueurs d'onde et la seconde plage de longueurs d'onde sont toutes les deux des plages de la région des infrarouges proches. En outre, la longueur d'onde centrale de la première plage de longueurs d'onde et la longueur d'onde centrale de la seconde plage de longueurs d'onde ont des valeurs mutuellement différentes. Une unité de calcul de température 20 est configurée pour calculer la température de la vapeur d'eau en utilisant le rapport entre l'intensité de la lumière dans la première plage de longueurs d'onde et l'intensité de la lumière dans la seconde plage de longueurs d'onde.

本発明は、気体の温度、特に水蒸気を含む気体の温度を非接触で精度よく測定することが可能な技術を提供するものである。分光部10は、水蒸気からの放射光から、少なくとも第1波長帯域における光強度と、第2波長帯域における光強度とを取得する。第1波長帯域と第2波長帯域とは、いずれも近赤外領域の帯域とされている。かつ、第1波長帯域の中心波長と第2波長帯域の中心波長とは、互いに異なった値とされている。温度算出部20は、第1波長帯域での光強度と、第2波長帯域での光強度との比を用いて、水蒸気の温度を算出する構成となっている。
