FLUID TEMPERATURE MEASURING APPARATUS AND GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a fluid temperature measuring apparatus applicable to a wide flow velocity range.SOLUTION: A fluid temperature measuring apparatus 100 comprises: a structure 20 in which a space V where a fluid F to be measured is present is defined and formed and in which a hole part communicating with the space V is formed; a temperature detection unit 11 detecting the temperature of the fluid F in the hole part; a suction pump 30 attracting the fluid F in the space V to outside via the hole part; and a control device 40 controlling an output from the suction pump 30, and the control device 40 has an output increase unit 41 controlling the output from the suction pump 30 so as to gradually increase the output from zero and an output stop unit 42 stopping the output increase unit 41 from increasing the output when a change rate of the temperature detected by the temperature detection unit 11 becomes not higher than a preset threshold.SELECTED DRAWING: Figure 2
