る。[Advantage of the Invention] As described in detail above, according to the temperature distribution detection sensor of the present invention, the sheath type thermocouple or the sheath type resistance thermometer, the sheath type dummy member, the metal fin, the porous insulating refractory are used as the sheath sheath. A sensor can be manufactured by simply forming a temperature-sensitive mechanism member that is housed in a pipe in advance and then storing this temperature-sensitive mechanism member in a metal sheath with the interposition of heat-resistant cement such as coating. The sensor can be simplified, the sensor can be mass-produced, and the manufacturing cost can be significantly reduced. Furthermore, since the sheath tube, the metal fin, the thermocouple or the resistance thermometer, and the sheath-type dummy member are adhered and fixed to the temperature-sensing mechanism member by reducing the diameter of the outer sheath tube, the metal fin is Not only as a heat transfer member for increasing the temperature measurement response sensitivity and temperature measurement accuracy in the transverse direction of the furnace, but also as a reinforcing member for maintaining the mechanical strength of the temperature sensitive mechanism member and a shielding member for maintaining the internal airtightness. Since it functions, the outer sheath tube is in its original shape, there are no stress concentration points, and the mechanical strength is high, so that the strength can be made reliable.
また、金属製鞘の外周面にセラミック材が溶射されて
いるので、アルカリ性蒸気やCOガスが存在する悪環境下
における耐久性を大幅に高めることが可能である。Further, since the ceramic material is sprayed on the outer peripheral surface of the metal sheath, it is possible to significantly improve the durability in a bad environment where alkaline vapor or CO gas exists.
