GAS TEMPERATURE NONCONTACT MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a noncontact gas temperature measuring device for measuring the temperature in a high pressure-high temperature gas atmosphere. SOLUTION: This gas temperature noncontact measuring device is constituted by having a laser beam irradiating means 13 for irradiating the inside of an area where passing high pressure-high temperature gas 11 in a high pressure-high temperature gas passage 10 with a laser beam 12, and a measuring detector 15 for receiving the transmitted light 14 of the irradiation laser beam 12.
