先端測定部は、ガス流路４内に突出しており、支
持管５の内方に突出した３条の突起５ａによつて
ほぼガス流路４と平行に位置させられる。 Reference numeral 6 denotes a platinum-rhodium thermocouple inserted into the passage 3 formed by the insertion rod 2 and the outer tube 1; It is positioned approximately parallel to the gas flow path 4 by the three protrusions 5a that protrude in the direction.
７は通路３内に充填されるセラミツク製粉末で
あつて、白金て反応しないアルミナを使用してい
る。 7 is a ceramic powder filled in the passage 3, and is made of alumina which does not react with platinum.
なお１ａは管１より突出しガス流路４の下流側
を絞る突起である。 Note that 1a is a protrusion that protrudes from the pipe 1 and narrows the downstream side of the gas flow path 4.
このようにしてなる装置によつて流体Ａの温度

破損することもない。 Furthermore, since the thermocouple 6 protrudes into the gas flow path 4 through the passage 3 filled with ceramic powder 7, its wiring portion is reinforced and does not come into contact with the fluid A, preventing fluid vibrations and high temperatures. It will not be damaged by tension or the like.
更にまた、熱電対６を支承する支持管５は、輻
