【考案の詳細な説明】
本考案は応答の速い測温抵抗体に関するもので
ある。[Detailed Description of the Invention] The present invention relates to a rapid response temperature measuring resistor.
従来測温抵抗体の時間遅れの小さいものはシー
ス型測温抵抗体が用いられているが、これらはシ
ース外径がいづれも3.2m／ｍ〜6.4m／ｍと細径
のため流速や振動、衝撃などの著しいところで用
いた場合には曲つたり、折れたり、破損する欠点
があつた。 Conventional resistance thermometers with a small time delay are sheathed resistance thermometers, but these have small sheath outer diameters of 3.2 m/m to 6.4 m/m, so they are susceptible to flow velocity and vibration. They had the disadvantage of bending, breaking, or breaking when used in places subject to severe impact.
また従来のマイカ捲型の太径（10m／ｍ〜
15m／ｍ）の測温抵抗体では時間遅れが大きく時
定数63.2％で40〜80秒程度となつていた。 In addition, the conventional mica winding type has a large diameter (10 m/m ~
15m/m) had a large time delay of about 40 to 80 seconds with a time constant of 63.2%.
本考案は以上の欠点をなくするため測温抵抗体
で太径で時間遅れの小さい応答の速いものを提供
するものである。 In order to eliminate the above-mentioned drawbacks, the present invention provides a resistance temperature detector with a large diameter, a small time delay, and a fast response.
測温抵抗体の応答を速くするにはイ．抵抗素子
への熱伝導をよくする。ロ．全体の熱容量が小さ
い等が必要であるが、この条件を充足するために
保護パイプの感温部の内面に、できるだけ小さく
した抵抗素子を密着させて、耐振、耐衝撃性の強
いものをえんとするものである。 How to speed up the response of a resistance thermometer a. Improves heat conduction to the resistance element. B. It is necessary that the overall heat capacity be small, but in order to satisfy this condition, a resistor element as small as possible is attached tightly to the inner surface of the temperature-sensing part of the protection pipe, and a material with strong vibration and impact resistance is used. It is something to do.
これらを満足させる測温抵抗体は第１図に示す
ごとくフイン１′付板ばね１に保護パイプ２を溶

い測温抵抗体を提供するものである。なお抵抗素
子３と保護パイプ２の間隙に耐熱セメントを入れ
密着をよりよくすることもできるものである。 As shown in Fig. 1, a resistance temperature detector that satisfies these requirements is obtained by welding a protective pipe 2 to a plate spring 1 with fins 1', and then inserting a built-in resistance element 3 into the protective pipe 2 and attaching it to a metal protective tube 4. The purpose is to provide a quick-response temperature measuring resistor in which the protection pipe 2 is inserted through the metal protection tube 4 and comes into contact with the inner surface of the metal protection tube 4. It is also possible to insert heat-resistant cement into the gap between the resistance element 3 and the protection pipe 2 to improve their adhesion.
以上のようにして太径でも応答の速い測温抵抗
体が得られるものである。 In the manner described above, a resistance temperature detector with a fast response even with a large diameter can be obtained.
