It is a high-resistance, quick-response type in which multiple small resistance elements are arranged on the outer circumferential surface of a pipe, each small resistance element is connected in series, and the pipe is inserted and fixed to the outer circumference via heat-resistant cement. It is a resistance temperature sensor.

Next, after applying ceramic cement 4 to the surface of the resistance element 1, the outer pipe 3 is inserted, and the inner pipe 2 and the outer pipe 3 are welded 7. Furthermore, insulator 6 is attached to lead wire 5.
After that, the guide pipe 9 is attached and welded to the outer pipe 3 (7).
「考案の効果」
本考案は、上述のように、パイプの外周面に複
数個の小型抵抗素子を配置し、各小型抵抗素子を
直列に接続し、更にその外周に耐熱セメントを介

This is a high-resistance, quick-response type resistance temperature sensor that is inserted and fixed, and although it has a high resistance, it can be miniaturized and has a high quick response.
また、小型対抗素子の個数を増減することによ
り種々の抵抗値の高抵抗のものが作れる。 Further, by increasing or decreasing the number of small counter elements, high resistance devices with various resistance values can be manufactured.
尚、抵抗素子は内側パイプの先端が中空となつ
ておるので熱容量を小さくすることができ更に外
側パイプの内周に耐熱セメントを介して設置され
ているため応答性がよい、内外共薄肉パイプで保
護されているので振動や衝撃に強い構造である。 The resistance element has a hollow tip on the inner pipe, which reduces heat capacity, and it is installed on the inner periphery of the outer pipe with heat-resistant cement, providing good response. Because it is protected, it has a structure that is resistant to vibrations and shocks.
またガイドパイプは長さは自由で内部にMgO
等絶縁物を充鎮し耐振性を更に強くすることが可
能である。 In addition, the guide pipe can be of any length and has MgO inside.
It is possible to further strengthen the vibration resistance by filling with an equivalent insulator.
