Conventionally, a dip-type thermocouple thermometer has been used for the temperature of hot metal or the like, but this type of thermometer has a problem that it is difficult to obtain timely information because continuous temperature measurement is difficult. After that, a radiation thermometer was developed to immerse the protective tube in hot metal etc. and measure the temperature by the radiation from the protective tube.

維を巻いて保護している。In this radiation thermometer, a flange pipe 4 is provided between the measuring device 3 and the protective pipe 2 in order to protect the radiation temperature measuring device 3 from the high radiant heat of the hot metal. The flange tube 4 exposes most of it to the inside of the hot metal cover 7,
Since it receives strong radiant heat from the hot metal 1, a stainless steel tube is used, and a fire resistant fiber such as glass fiber is wrapped around the stainless tube to protect it.
