に押し込む力が容易に得られる。Further, a required number of column-shaped fasteners 7 through which the MI cable 4 and the sheath thermocouple 3 are freely movably penetrated, and at least one fastener 7 is provided on the sheath thermocouple 3 and the fastener 7 is provided.
Since it is configured with the fixing metal fitting 8 for restricting the movement of the guide wire, the required number of the metal fittings 7 function as a flexible guide while slightly shifting the sheath thermocouple 3 with respect to the meandering guide tube. In addition, since the fixing metal fitting 8 is fixed to the sheath thermocouple 3, the sheath thermocouple 3 exists at the axial center of the device, and therefore, when the sensor units 2 and 3 are inserted into the guide tube. , It is easy to get the force to push it straight without bending and clogging like in the case of a thin lead.
また、MIケーブル４の、例えば一本が、案内管の内壁に
引っ掛かっても、案内管に詰まる事無く、そのMIケーブ

一長で良い事も起こり得る。Also, with respect to the meandering guide tube, one MI cable 4 has a large radius of curvature and the other MI cable 4 has a small radius of curvature, which causes a difference in required length. Since it penetrates freely with respect to, the MI cable 4 on the side with a small radius of curvature does not sag, and there is no possibility that it will hinder smooth insertion into the guide tube.
In addition, if there is a portion with a small radius of curvature and a portion with a large radius of curvature in one MI cable 4, they may be canceled out and all MI cables 4 may have the same length.
したがって、センサ本体部は保護管への挿入、抜取りが
容易なものがえられる。Therefore, the sensor main body can be easily inserted into and removed from the protective tube.

起こり得る。Also, with respect to the meandering guide tube, the radius of curvature of one MI cable becomes large and the radius of curvature of the other MI cable becomes small, causing a difference in the required length, but the MI cable moves with respect to the stopper. Since it penetrates freely, there is no risk that the MI cable on the side with a small radius of curvature will sag and hinder smooth insertion into the guide tube. Also, a bottle of
If there is a small radius of curvature and a large radius of curvature in the MI cable, they may be offset, and the mutual MI cables may have the same length.
