この考案は、容器あるいは流路の温度を計測す
る温度計測装置に関するものである。[Detailed Description of the Invention] This invention relates to a temperature measuring device that measures the temperature of a container or a flow path.
従来用いられているこの種温度計測装置として

４の温度を熱電対温度計１５で計測し、炉内ガス
温度としている。 An example of a conventionally used temperature measuring device of this type is shown in FIG. That is, the detection tube 12 having a hollow cylindrical shape is inserted up to the center 11 in the furnace, and after the tip portion 13 of the detection tube 12 is made to match the gas temperature in the furnace, the inner tip 1 of the detection tube 12 is inserted.
The temperature of No. 4 was measured with a thermocouple thermometer 15, and was taken as the furnace gas temperature.

る。 The detection tube 12 is inserted into a hole formed in the furnace wall 17 and the heat insulating material 16. That is, a flange 18 for attaching a thermocouple thermometer 15 is projected from the furnace wall 17, and the thermocouple thermometer 15 is fitted from the rear end of the detection tube 12.
しかるに、この従来の温度計測装置における検

化がはげしく耐久性に欠ける。一方、白金は高価
で実用向きでない。 However, the detection tube 12 in this conventional temperature measuring device is made of metal with excellent heat resistance and pressure resistance because it is necessary to perform measurements in a high temperature and high pressure atmosphere. That is, in order to withstand high temperatures of 1000°C or higher, it is necessary to use Inconel, tantalum, platinum, etc. as the metal material. However, these materials, except for platinum, oxidize very strongly in an oxidizing atmosphere and lack durability. On the other hand, platinum is expensive and not suitable for practical use.
また、検出筒１２の肉厚が厚くなり、温度計１
５の熱応答性が悪くなる。などの欠点がある。 In addition, the thickness of the detection tube 12 becomes thicker, and the thermometer 1
The thermal response of No. 5 becomes worse. There are drawbacks such as.

温度計測装置を提供することにある。 This idea was made to solve these conventional problems, and consists of a hollow ceramic detection tube that penetrates the wall that constitutes the container or flow path, and has a closed end that projects inside the wall. , a thermometer that closes the protruding end on the outside of the wall of the detection cylinder and measures the temperature of the protrusion on the inside of the wall of the detection cylinder, and a gas supply that supplies gas having a pressure higher than the pressure inside the wall into the detection cylinder. An object of the present invention is to provide a temperature measuring device characterized by having a device.
以下、図面を参照してこの考案の実施例につい
て詳細に説明する。 Hereinafter, embodiments of this invention will be described in detail with reference to the drawings.
第２図において、炉外に温度計２５を取り付け

熱材２６に夫々検出筒挿入孔をあけ、該挿入孔に
は、中空円筒状のセラミツク製の検出筒２２をそ
の閉じた先端が炉の内部に位置するように挿入す
る。 In FIG. 2, a detection tube insertion hole is formed in the furnace wall 27 and the heat insulating material 26 from which a flange 28 for attaching a thermometer 25 is projected outside the furnace. The tube 22 is inserted so that its closed end is located inside the furnace.
温度計２５は、熱電対を利用したもので、その
温接点は検出筒２２の閉じた先端部分に固定さ
れ、また、そのリード線は、フランジ２８を通つ
て外部へ導出されている。 The thermometer 25 utilizes a thermocouple, and its hot junction is fixed to the closed end portion of the detection tube 22, and its lead wire is led out through a flange 28.
３０は、上記フランジ２８に固定された蓋で、
該蓋３０は検出筒２２を開口端部を閉じると共
に、熱電対温度計２５のリード線の取り出し部分
を密封するもので、耐熱絶縁体３０′を有してい
る。 30 is a lid fixed to the flange 28;
The lid 30 closes the open end of the detection tube 22 and seals the lead wire of the thermocouple thermometer 25, and has a heat-resistant insulator 30'.
２９は、気体供給管で、蓋３０を貫通し検出筒
２２の内部と連通している。 Reference numeral 29 denotes a gas supply pipe that passes through the lid 30 and communicates with the inside of the detection tube 22 .
さて、セラミツク製の検出筒２２の内面に取り
付けた温度計２５は、検出筒２２が高温ガスによ
つて熱つせられ、それにより温度計２５の熱電対
温接点に熱が伝達され熱起電力が発生する。この
熱起電力をリード線を介して図示しない計器に導
き、温度を計測する。 Now, the thermometer 25 attached to the inner surface of the detection tube 22 made of ceramic is heated by high-temperature gas, which causes heat to be transferred to the hot junction of the thermocouple of the thermometer 25, causing a thermoelectromotive force. occurs. This thermoelectromotive force is guided to a meter (not shown) via a lead wire, and the temperature is measured.
一方、気体供給管２９から供給される窒素ガス
などにより炉内の圧力よりも若干高い（0.5〜１
Kg／cm2）圧力に検出筒２２内部を維持する。この
ため、検出筒２２に圧力歪が生じることは少な
い。従つて、検出筒２２がセラミツク製のもので
あつたとしても、その寿命は格段に長くなる。 On the other hand, due to nitrogen gas supplied from the gas supply pipe 29, the pressure is slightly higher than the pressure inside the furnace (0.5~1
Kg/cm 2 ) pressure is maintained inside the detection tube 22. Therefore, pressure strain is less likely to occur in the detection tube 22. Therefore, even if the detection tube 22 is made of ceramic, its lifespan will be significantly longer.
万一、セラミツク製の検出筒２２が破損するよ
うな場合が生じたとしても、フランジ２８に固定
した蓋３０によつて検出筒２２の壁２７突出側は
閉じられているので、炉内の高温・高圧の燃焼ガ
スが、外部に噴き出すことはない。 Even if the ceramic detection tube 22 were to be damaged, the protruding side of the wall 27 of the detection tube 22 is closed by the lid 30 fixed to the flange 28, so the high temperature inside the furnace can be avoided.・High-pressure combustion gas does not blow out to the outside.
