す。The sheath type thermocouple device having such a configuration is widely used to electrically measure various temperatures by being connected to its control and measurement circuit, and its operating principle and method are well known. In the conventional sheath type thermocouple device name, especially the sheath 1
In order to achieve sufficient thermal contact between the closed end 15 of thermocouple element 1 and the junction point 14 of thermocouple element 10 and to ensure the flexible retention of thermocouple element 1 within sheath 11, the sheath The inner space of 11 was filled with a filler 17 made of ceramic such as alumina so as to embed the thermocouple element 1o. In FIG. 3, reference numeral 18 indicates a tube material connected to the sheath 11 for guiding the wire 12.13, and the tube material 18 is filled with epoxy resin or the like so as to embed the wire 12.13. The filling material 19 is filled. code 2

される。To manufacture such a sheath type thermocouple device, a long and thin tube is generally required as the sheath 11, and it is difficult to insert the thermocouple element 1o and filler 17 into this long and thin sheath 11, so wire drawing is difficult. Adopted. That is, initially, a relatively thick tubular sheath 1 closed at one end is used.
1, the thermocouple element 10 and the filler 17 are charged, and the sheath 11, together with the thermocouple element 10 and the filler 17 therein, is then drawn to a predetermined small diameter.

場合には、従来方式のシース型熱電対装置は採用できな
い。(Problems to be Solved by the Invention) During the wire drawing process for producing the above-mentioned thin sheath type thermocouple device, the wires 12 and 13 of one thermocouple element 10 are also stretched, so that one of the wires If the tensile strength of the wires 12 and 13 is so low that there is a risk that the wires will break during stretching, the conventional sheath type thermocouple device cannot be used.

どのおそれが生じる。For example, gold-iron (Au + 0.07 at-Fe) vs. chromel thermocouple elements, which can be used for temperature measurement from room temperature to extremely low temperatures, cannot be used with conventional sheaths because the gold-iron wire has low tensile strength. It cannot be used in type thermocouple devices. Therefore, gold-iron to chromel thermocouple elements have been used as bare wires (completely bare wires or wires with repeats attached) without being encased in a sheath. If you try to use the bare wire as it is, there will naturally be a risk of short circuits due to disconnection or peeling of the coating.

4 thermocouples in the sheath! ! Since the element is contained within the plastic tube except near its joint points and therefore does not need to be embedded in the filler as a whole, no wire-drawing is necessary for its fabrication, and therefore the element has a low tensile strength. It has the effect that lines can also be used. Furthermore, the junction point of the strands and its vicinity that are not protected by the plastic tube are sufficiently held by the sheath through the filler filled around this area, and are sufficiently thermally protected from the closed end of the sheath. come into contact with.

Furthermore, the space between the plastic tube that surrounds the sheath and the sheath is a hollow space with no filler material, except for the area near the joint, so when the wire is heat-shrinked and the sheath is bent and used, There is no risk of the strands breaking due to excessive force. Moreover, the filling material is filled in the sheath near the closed end so as to embed the junction point of the external couple element and both of the wires near it, so the junction point of the wire that is not preserved in the plastic tube and the The surrounding area is filled with filler material,
fully held by the sheath and the sheath closed; the shore fully contacts (J'3'tζ).

According to the present invention, thermocouple sleeve materials such as gold-iron vs. chromel that have been used in wires can be used without fear of disconnection or short-circuiting because they are protected by a sheath and a plastic tube. Furthermore, by protecting such a thermocouple element with a sheath and a plastic tube, a hot air couple device that is resistant to high frequency noise can be obtained.
