本発明は電気的計測用ワイヤーをセラミックなどの絶縁
体中に埋設してなる計測用ワイヤーに係わるものである
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a measuring wire formed by embedding an electrical measuring wire in an insulator such as ceramic.
従来電気的計測用ワイヤーを芯部に内設して、その周縁
をマグネシア等の絶縁粉体で充満させてなるものとして
、熱電対としてのセンサーなどが一例である。An example of a conventional sensor such as a thermocouple is one in which an electrical measuring wire is installed inside a core and the periphery is filled with insulating powder such as magnesia.
之等の従来の製品は、芯部に設置する電気的計測用金属
線として、クロメル、アルメロ、コンスタンタン、口金
線等が使用され、それ等の金属線の1ミリ以上の外径の

殻金属体ごと圧延、引抜き等の塑性加工を施して芯部に
設置されたる金属線をも減径加工して、所望の外径の熱
電対を製作して来たものである。In conventional products such as these, chromel, armello, constantan, cap wire, etc. are used as the metal wire for electrical measurement installed in the core, and those with an outer diameter of 1 mm or more are used. An insulator such as magnesia is inserted through a hole with a certain diameter, and the outer shell is coated with a metal such as stainless steel, and the outer metal body is rolled with rollers, dies, etc. A thermocouple with a desired outer diameter is manufactured by reducing the diameter of the metal wire installed in the core by performing plastic processing such as drawing.
この従来の方法では、塑性加工を繰返しそのたびに焼鈍
工程をも必要とする、などの煩雑な工程を要するもので
あり、かつそれ等の工程も相当の熟練を必要とし、製造
設備も多大なる投資が必要である。またこれ等の従来の
方法の致命的欠陥は、絶縁体中における金属線の減径と
いう困難な工程を径でいるために金属線の断線の事故が
発生することである。また完成品として市場に提供され
ているものも、之等の従来の方法で製作されているもの
は、金属線の表面が相当損傷を受けているものであるが
故に既に劣化しているものと推察されるものである。This conventional method requires complicated processes such as repeated plastic working and an annealing process each time, and these processes also require considerable skill and require a large amount of manufacturing equipment. Investment is required. Furthermore, a fatal flaw in these conventional methods is that the difficult process of reducing the diameter of the metal wire in the insulator causes accidents such as breakage of the metal wire. In addition, the finished products that are manufactured using conventional methods such as those offered on the market are considered to have already deteriorated because the surface of the metal wire has been considerably damaged. It can be inferred.
蕊に本発明のものを提供する根拠が存するものである。There is a basis for providing the present invention to stamens.
即ち本発明の方法は従来のものと異なり、絶縁体中で金
属線を減径するという工程を径ないで所望の外径のセン
サーを製作し得るものである。That is, the method of the present invention is different from conventional methods in that it is possible to manufacture a sensor with a desired outer diameter without the step of reducing the diameter of the metal wire in an insulator.

覆されている21の絶縁粒体を収縮させる効果がある。The present invention will be described in detail. FIG. 1 is a shape diagram of an embodiment according to the present invention. 1 is a metal wire that generates an electromotive force, such as Armello or Constantan. 2 is an insulator such as soft mud-like magnesia or alumina. Fig. 2 is an enlarged view of the soft mud state of No. 2. 21 is fired fine particles such as magnesia or alumina, and 22 is a binder such as silicone oil or paraffin. This 22 binder is 50
It is evaporated by heating at 0° C. to 500° C., and has the effect of shrinking the 21 insulating particles covered by it.
このようにして、軟泥状のものをバインダーを蒸散させ
る程度で加熱し、芯部の1の金属線の融点は1000℃
を越えるものであるから全く影響を受けない筈である。In this way, the soft mud-like material was heated to the extent that the binder evaporated, and the melting point of the metal wire 1 in the core was 1000°C.
It should not be affected at all since it exceeds the above.
このようにして加熱したのちに2の外表面に接水性樹脂
でコーテングする、または金属粉末を溶射して被覆する
。After heating in this manner, the outer surface of 2 is coated with a water-wetting resin or coated with metal powder by thermal spraying.
第3図の5外表面をコーテングした状態のものである。This is the state in which the outer surface of 5 in FIG. 3 is coated.
本発明のセンサーはセラミックにより芯線である金属線
を埋設し得ることを極めて容易になし得るものであるが
故に従来のような致命的事故となる断線など製作中に起
り得ないという顕著なる利点を有するものである。The sensor of the present invention has the remarkable advantage that the metal wire, which is the core wire, can be buried very easily in the ceramic material, and therefore, there is no possibility of wire breakage, which can be a fatal accident, during production, as in the case of the conventional sensor. It is something that you have.
