化を防止できる。In this thermal lightning thermometer, the thermocouple 5 uses elements 5a and 5b made of tungsten (melting point 3410°C) and rhenium-containing tungsten (melting point 2800°C), so it can withstand high temperatures of 1800°C or higher. Temperature can be measured even at low temperatures without melting. This thermocouple 5 is protected by an inner tube 2 via a heat-resistant insulator 7. Since the inner tube 2 is made of tantalum, for example, 18
It does not melt even at high temperatures of 00° C. or higher, and the inner tube 2 does not react with the thermocouple 5 and the heat-resistant insulator 7. Furthermore, the inner tube 2 is surrounded by the outer tube 1 and is shielded from the external oxidizing atmosphere so that it is not directly exposed to it. Since the outer tube 1 is made of zirconia, for example, even if the outside is in an oxidizing atmosphere at a high temperature of 1800° C. or higher, the airtightness will not be impaired and it will not melt. Moreover, since the ceramic forming the outer tube 1 is airtight, external air does not pass through the outer tube 1 and enter the inside of the tube. The inner tube 2 is thereby protected by the outer tube 1. Note that since the outer tube 1 made of zirconia and the inner tube 2 made of tantalum react with each other at temperatures above 1800°C, a gap is formed between them, and tungsten, which does not react with the inner tube 2, is inserted into this gap. Coil 8 consisting of
The inner tube 2 is supported so as not to come into contact with the outer tube 1. Further, the gap between the inner tube 2 and the outer tube 1 is made into a non-oxidizing atmosphere to prevent the inner tube 2 from being oxidized. Therefore, by combining these structures, the thermocouple 5 and the inner tube 2 can be protected from an oxidizing atmosphere at a high temperature of 1800° C. or higher, thereby preventing oxidation.

での温度測定にも使用することができる。Therefore, this thermocouple thermometer can be used by being installed in an oxidizing atmosphere at a high temperature of 1800° C. or higher, and the temperature of the object to be measured can be fixed at a. Specifically, 230 in an oxidizing atmosphere.
Temperatures down to 0°C can be measured. For example, in a nuclear reactor simulation test device, the temperature near the simulated fuel rods is 180℃.
Although it is 0°C or higher, the temperature at this location can also be fixed by δ-1. Furthermore, it can be used for temperature measurement not only in an oxidizing atmosphere but also in a non-oxidizing atmosphere.
なお、外側管１の内部で内側管２を支持する支持部材は
実施例のものに限定されず、他のものでもよい。例えば
耐熱性絶縁粉末を使用してもよい。Note that the support member that supports the inner tube 2 inside the outer tube 1 is not limited to that of the embodiment, and may be of other types. For example, heat-resistant insulating powder may be used.
