TEMPERATURE SENSOR ASSEMBLY FOR HIGH TEMPERATURE GAS HAVING IMPROVED DURABILITY AND RESPONSIVENESS, AND TEMPERATURE MEASURING METHOD FOR HIGH TEMPERATURE GAS USING THE TEMPERATURE SENSOR ASSEMBLY

摘要

The present invention relates to a temperature sensor assembly for a high-temperature gas with improved durability and responsiveness for measuring the temperature of a high-temperature combustion gas emitted from a combustor such as a gas turbine, and a method for measuring the temperature of a high-temperature gas using the same. The temperature sensor assembly for high temperature gas with improved durability and responsiveness according to the present invention includes a fixed plate 124 fixed to one side of a combustion chamber, and installed on one side of the fixed plate 124 and formed with an end open. A protective tube 121 and a temperature sensing member installed inside the protective tube 121 at a distance from the protective tube 121 and filled with combustion gas or installed through the fixed plate 124 A space is formed so as to be provided, and an end portion includes a protective dome 122 formed in a closed state, and the protective tube 121 and the protective dome 122 are exposed to combustion gas so that the temperature sensing member is burned. It is characterized by measuring the temperature of the gas.
