ばねを示す。The sheath type thermocouple device having such a structure is widely used for electrically measuring various temperatures by being connected to the control measuring circuit, and its operating principle and operating method are also well known. In the conventional sheath type thermocouple device, the sheath 11
The interior of the sheath 11 to ensure sufficient thermal contact between the closed end 15 and the junction 14 of the thermocouple element 10 and to ensure mechanical retention of the thermocouple element 10 within the sheath 11. A space, a filling material 17 made of a ceramic such as alumina was filled so as to embed the thermocouple element 10. In FIG. 3, reference numeral 18 denotes a pipe member connected to the sheath 11 for guiding the wires 12, 13, and the wires 12, 13 are embedded in the pipe member 18 such as epoxy resin. Filling material 19 is filled. Reference numeral 20 indicates a coil spring for protecting the wires 12 and 13.

に、所定の小さな直径まで線引き加工される。In order to manufacture such a sheath type thermocouple device, an elongated tube is generally required as the sheath 11, and this elongated sheath is used.
Since it is difficult to put the thermocouple element 10 and the filler 17 in 11, wire drawing is adopted. That is, first, the thermocouple element 10 and the filling material 17 are charged into the relatively thick tubular sheath 11 closed at one end, and then,
The sheath 11 is drawn to a predetermined small diameter with the thermocouple element 10 and the filler material 17 therein.

When the tensile strength of the wires 12 and 13 is weak and there is a risk of the strands being cut during stretching, the conventional sheath type thermocouple device cannot be adopted.

じる。For example, the gold-iron (Au + 0.07at% Fe) vs. chromel thermocouple element that can be used for temperature measurement from room temperature to extremely low temperature, the tensile strength of the gold-iron wire is weak, so the conventional sheath type thermocouple Cannot be used in equipment. As such, gold-iron vs. chromel thermocouple elements have been used bare wire (completely bare wire or wire with a coating attached) without being housed in a sheath. If the bare wire is used as it is, naturally, there is a possibility that the wire will break or a short circuit will occur due to peeling of the coating.

る。(Means for Solving the Problems) In order to solve the above-mentioned problems, according to the present invention, a thermocouple element composed of two wires is inserted into a sheath having a closed end and an open end, Join one end of both strands together near the closed end of the sheath to form a joint, and extend the other end of the strands outward through the open end of the sheath to create a joint near the closed end of the sheath. And a sheath type thermocouple device which is filled with a filling material that fills only both strands in the vicinity thereof, and the sheath is made of a sheath with a small tube diameter that does not require wire drawing, and is joined in the sheath with a small tube diameter. It is characterized in that each strand, which is difficult to draw, is contained in a plastic pipe in a slightly loose state except for the area near the point.

Since it does not have to be housed and thus embedded in the filler as a whole, it has the effect that no wire-drawing process is required for its manufacture, and thus strands of low tensile strength can also be used. By accommodating the individual wires, which are difficult to be drawn, in the plastic tube in a slightly loose state, it becomes possible to prevent the individual wires from being broken due to bending of the thermocouple. Moreover, the joining point of the strands not protected by the plastic tube and the portion in the vicinity thereof are sufficiently held by the sheath via the filling material filled around this portion,
And sufficiently thermally contact the closed end of the sheath.

特徴とするシース型熱電対装置。A thermocouple element consisting of two wires is inserted into a sheath having a closed end and an open end, and one ends of both wires are joined together near the closed end of the sheath. A sheath formed by extending the other ends of both strands to the outside through the open end of the sheath, and filling only the joining point near the closed end of the sheath and the strands near that junction. In the thermocouple device, the sheath consists of a sheath with a thin tube diameter that does not require wire drawing, and in the sheath with a thin tube diameter, except for the area near the joint, A sheath type thermocouple device, which is housed in a slightly loose state.
