Description
【発明の詳細な説明】 本発明は複数箇所の温度を測定する方法に関する。[Detailed description of the invention] The present invention relates to a method of measuring temperatures at multiple locations.
従来複数箇所の温度を測定するには熱電対をそれぞれの
箇所に移動して回るか、もしくは複数の熱電対をそれぞ
れの箇所に布設しておくことが考えられていた。Conventionally, in order to measure the temperature at multiple locations, it has been considered to move thermocouples to each location or to install multiple thermocouples at each location.
もちろん熱電対の端末には検知器などが取り付けられて
おり、場所によっては熱電対を移動することが困難な場
合がある。Of course, a detector is attached to the terminal of the thermocouple, and depending on the location, it may be difficult to move the thermocouple.
また、測定したい箇所ごとに熱電対を布設するという方
法は測定箇所がかなり多くなると不経済であり必ずしも
便利ではない。Furthermore, the method of installing thermocouples at each location to be measured is uneconomical and not necessarily convenient if the number of measurement locations increases considerably.
そこで、熱電対そのものを移動することなく。Therefore, without moving the thermocouple itself.
１対もしくは少ない対数の熱電対によって多数箇所の温
度を測定することができれば甚だ便利である。It would be extremely convenient to be able to measure temperatures at multiple locations using one pair or a small number of thermocouples.
第１図は本発明の基礎となった原理を示す説明図であり
、２種の異なる導線１，２を互いに直接接触することな
く並行させて布設し、一端には温度検知器すなわち電流
計４が設けである。FIG. 1 is an explanatory diagram showing the principle on which the present invention is based, in which two different types of conductors 1 and 2 are laid in parallel without being in direct contact with each other, and a temperature sensor, that is, an ammeter 4 is installed at one end. is the provision.
３は接触子であり、導線１，２を電気的に短絡している
。3 is a contact, which electrically short-circuits the conducting wires 1 and 2.
すなわちこの装置によれば接触子３付近の温度が測定で
きるわけであるから、この接触子３を移動することによ
って導線１，２の長手方向に沿って多数の位置の温度が
測定できるものである。In other words, since this device can measure the temperature near the contact 3, by moving the contact 3, it is possible to measure the temperature at many positions along the length of the conductors 1 and 2. .
ところが、このような方法で最も問題となるのは、如何
にしてこの接触子３を的確に所定の位置に移動するかで
ある。However, the biggest problem with this method is how to accurately move the contact 3 to a predetermined position.
特に熱電対を移動することが困難な場所においては、接
触子３を移動することもまた困難である場合が多く、密
封された長尺管の内部温度の測定などの場合は、まさに
不可能にも等しい。It is often also difficult to move the contact 3, especially in locations where it is difficult to move the thermocouple, and in some cases, such as measuring the internal temperature of a sealed long tube, it may even be impossible. are also equal.
本発明は斯かる状況に鑑み、一対もしくは少数の熱電対
を用いて、これを特に移動することなく複数の位置にお
ける温度を測定することができる温度測定方法を提供す
ることを目的とする。In view of this situation, an object of the present invention is to provide a temperature measuring method that can measure temperatures at a plurality of positions using a pair or a small number of thermocouples without having to move them.
本発明の構成を、一実施例を示す第２図を参照して具体
的に説明する。The configuration of the present invention will be specifically explained with reference to FIG. 2 showing one embodiment.
熱電対を構成するための少くとも２種の導線１゜２を互
いに直接接触することなく並行させて布設し、この導線
１，２にはその長手方向の複数箇所にこれを短絡するこ
との可能なスイッチ３０を設ける。It is possible to lay at least two types of conducting wires 1 and 2 in parallel without making direct contact with each other to constitute a thermocouple, and to short-circuit these conducting wires 1 and 2 at multiple points in the longitudinal direction. A switch 30 is provided.
このスイッチ３０はそれ自体磁性体で造られていてもよ
く、また銅片と鉄片の複合体のようなものでもよいが、
磁石５を近づけると閉じ、遠ざけると開くように構成す
る。This switch 30 itself may be made of a magnetic material, or may be a composite of a piece of copper and a piece of iron.
It is constructed so that it closes when the magnet 5 approaches and opens when it moves away.
このように構成したスイッチつき熱電対の長手方向に磁
石５を移動することにより、スイッチ３０の開閉箇所を
次々移動させ、複数位置における温度を測定する。By moving the magnet 5 in the longitudinal direction of the switch-equipped thermocouple constructed in this way, the opening/closing positions of the switch 30 are moved one after another, and temperatures at a plurality of positions are measured.
以上説明したような方法であれば１例えば密封長尺管の
内部の温度などであっても、外部から磁石を移動するこ
とによって測定可能であり、一般に熱電対の移動が難し
い場合にも、一対もしくは少数の導線によって多数の位
置における温度が測定できるものである。With the method explained above, it is possible to measure, for example, the temperature inside a long sealed tube by moving a magnet from the outside, and even when it is generally difficult to move a thermocouple, it can be measured by Alternatively, temperatures can be measured at multiple locations using a small number of conducting wires.
