が害されないという認識から出発している。The present invention is particularly applicable to patent No. 111 insofar as it creates a space-saving device and provides a rapid indication of temperature changes.
No. 3178 Hakama Kosho 57 General No. 95 (Nuka application 1977-14
4191) is another form of the pan-q temperature device. In this case, the present invention provides that instead of interconnecting the legs of the thermocouple directly to the measurement point, an electrical resistance suitable for measuring the noise voltage can be incorporated into the thermocouple without impairing the temperature measurement accuracy of the thermocouple. We start from this recognition.
それ故本発明の榎Ｕ溢装置では、電気抵抗が、熱電対の

有利であろう。Both legs forming a thermocouple therefore simultaneously serve as signal conductors for the noise voltage measurement, which is determined by electrical resistance. If it is not necessary to insulate the measuring point, the measuring device according to the invention can be constructed in such a way that one of the two legs of the thermocouple is formed in the form of a cord and the other leg is formed in the form of a tube, in which case the two legs of the thermocouple are It may be advantageous for the thermocouple to be arranged in such a way as to form a protective tube for the electrical resistance and the other leg led into the insulation of the thermocouple.

実証されている。In this embodiment, one of the legs of the thermocouple, which is simultaneously used as a signal conductor for the noise voltage, performs the function of a protective tube with a blocking effect. Owing to the space-saving design of the measuring device according to the invention, this device has a very wide range of applications. If the noise voltage is to be transmitted over a relatively large distance, i.e. when there is a relatively large distance between the measuring point and the amplifier, the legs of the thermocouple, which are formed as core wires, are connected to the thermoelectromotive force or the noise voltage. Embodiments of the side-warming device have proven to be very advantageous, in which each two electrical conductors are provided for connection to the display device.

明による渡り温装置の若干の実施例が記載されており、
以下において詳細に説明される。It is also possible to eliminate the ohmic resistance by means of three signal conductors if the conductors have very low ohms, as is the case when both legs are of tubular design. It is also advantageous when the electrical conductor connected to the leg formed in the core of the thermocouple forms the leg of the thermocouple, the measurement point being the connection point of the leg of the thermocouple connected to the electrical resistance. It is. The drawings show some embodiments of the thermal temperature device according to the invention,
It will be explained in detail below.
第１図では保護管１に充填された絶縁体２内に１個の熱
電対を形成する双方の脚３，４が導かれる。In FIG. 1, the two legs 3, 4 forming a thermocouple are guided into an insulator 2 filled in a protective tube 1.

遮蔽物として使用すべきときに特に有利な実施形態は第
２図に示す通りである。The protective tube 1 is sealed at the other end with a suitable compound 7, in which case the legs of the thermocouple are formed in the form of a cord, as in the embodiment described in FIG. When it is connected, it is inserted through the sealing part and connected to a device that displays thermoelectromotive force or noise voltage, which is not shown in the drawings. In the thermostat according to the invention, the legs 3 and 4 of the thermocouple are therefore simultaneously used as signal conductors for the noise voltage. A switch is provided for selectively switching the device to display thermoelectromotive force or noise voltage, but this is not shown in the drawing. Alternatively, it is also possible to capacitively neutralize the noise voltage so that both voltages are measured one after the other. A particularly advantageous embodiment is shown in FIG. 2 when there is no need to insulate the measuring point and when the protective tube 1 is to be used at the same time as a shield.

時に保護管１の機能を果す様に配置されている。第２図
の場合、保護管を兼ねた脚４の末端部５は脚３，４の間

る。In this case, the thermocouple chest 4 is of tubular design and is arranged in such a way that it at the same time fulfills the function of the protective tube 1. In the case of FIG. 2, the end portion 5 of the leg 4, which also serves as a protection tube, is set at a position where the potential difference or noise voltage between the legs 3 and 4 can be measured.
第３図に記載された実施例においては、熱電対の双方の
脚３及び４が各２本の導線８を介して表示装置に援続さ
れている。In the embodiment shown in FIG. 3, both legs 3 and 4 of the thermocouple are connected to the display device via two conductors 8 each.

されている様に、導線８を保護管１のそれ自体管状物９
内に導入することも効果的であろう。１０は導線８の接
続箇所である。This arrangement makes it possible to eliminate the ohmic resistance of the signal conductors through cross-correlation. In this case, as shown in FIG.
It would also be effective to introduce it internally. Reference numeral 10 indicates a connection point of the conducting wire 8.
第５図においては、熱電対の一方の脚が管状に形成され
、他方の脚は双方の導線８を介して指示装置に接続され
た今一つの実施例が示してある。In FIG. 5, another embodiment is shown in which one leg of the thermocouple is of tubular design and the other leg is connected via both conductors 8 to an indicating device.
この場合にも熱電対の管状に形成された脚４の電気抵抗

された脚３の双方の接続導線が、熱電対の保護管として
形成された脚４の特別な管状接続箇所９に導かれており
、これは必要な場合に極めて効果的である。In this case as well, because the electrical resistance of the tubular leg 4 of the thermocouple is low, it is possible to eliminate the resistance of the signal conductor in a simple manner. In the embodiment according to FIG. 6, the two connecting conductors of the thermocouple core-shaped legs 3 are led into a special tubular connection point 9 of the thermocouple leg 4, which is designed as a protective tube for the thermocouple. This is extremely effective when necessary.
第５図、第６図の場合も、末端部５は、第２図の場合と
同様に設定される。In the case of FIGS. 5 and 6, the distal end 5 is set in the same manner as in FIG. 2.
（発明の効果）
原発明では熱電対の外部に別の雑音抵抗を含む回路を接
続するのに対し、本発明は雑音抵抗６を脚３，４の末端
部５，５の間に挿入したので、省スペースの簡単な回路
が形成できる。(Effect of the invention) In the original invention, a circuit including another noise resistor is connected to the outside of the thermocouple, whereas in the present invention, the noise resistor 6 is inserted between the terminal parts 5 and 5 of the legs 3 and 4. , a simple space-saving circuit can be formed.
またこのように末端部５，５の間に雑音抵抗６を挿入し
たとしても原発明の場合に比べ温度測定精度が害される
ことはない。Further, even if the noise resistor 6 is inserted between the end portions 5, 5 in this way, the temperature measurement accuracy will not be impaired compared to the case of the original invention.
なぜならば原発明では異種金属の熱起電力の差異ｘ−ｙ

発明では異種金属の熱起電力（ｘ，ｙとする）は末端部
５，５でそれぞれ測定される。This is because in the original invention, the difference in thermoelectromotive force between different metals
Measurement point 2 (the reference numerals in the drawing of the original invention are used, the same applies hereinafter)
A separate noise resistor 1 is added to this. In contrast, in the present invention, the thermoelectromotive force (x, y) of different metals is measured at the end portions 5, 5, respectively.
そしてこの熱起電力ｘ，ｙの間に雑音抵抗６を挿入する
と正確な異種金属の熱起電力の差異ｘ−ｙは測定できな
いように思える。しかし、実際には原発明においても測
定箇所２に発生する熱起電力の差異ｘ‐ｙは別回路の雑
音抵抗によっても同様に変動を受けるから結局本発明の
簡易化した回路でも測定精度は大同小異である。そして
、従来は雑音抵抗は熱電対と別の回路に接続するという
固定観念を本発明は打ち破ったものと云える。If a noise resistor 6 is inserted between the thermoelectromotive forces x and y, it seems impossible to accurately measure the difference xy between the thermoelectromotive forces of different metals. However, in reality, even in the original invention, the difference x-y in the thermoelectromotive force generated at measurement point 2 is similarly affected by the noise resistance of another circuit. It is. Moreover, it can be said that the present invention breaks down the conventional idea that the noise resistor is connected to a circuit separate from the thermocouple.
