| 摘要 |
The purpose of the present invention is to achieve a long-life thermocouple junction without causing strength degradation due to fusion in a thermocouple mounting structure using a strengthened platinum-based thermocouple. The present invention provides a thermocouple mounting structure comprising an implement 1 that is formed using platinum, a platinum alloy, or an oxide dispersion-strengthened alloy, a strengthened platinum-based thermocouple 11, and a mounting part 4 at which a temperature measuring connection point 10 of the strengthened platinum-based thermocouple 11 is fixed to the portion to be measured of the implement, wherein the strengthened platinum-based thermocouple 11 has high-temperature strength such that the breakage time when a stress of 10 MPa is applied in an atmosphere of 1,100°C is at least 100 hours, the wire diameter of the strengthened platinum-based thermocouple 11 is between 0.1 mm and 2.0 mm, and the temperature measuring connection point 10 is diffusion bonded. |
