FIG. 1 is a side sectional view showing an example of a conventional platinum resistance temperature detector for surface temperature measurement (hereinafter simply referred to as a resistance temperature detector), in which 1 is a resistance element, 2 is a core of the resistance element 1, and 3 is a winding core of the resistance element 1. A resistance wire made of wire material such as platinum, with a wire diameter of
It is made of a wire rod of about 0.025 mm formed to have a predetermined resistance value. 4 is a lead wire that connects the resistance wire 3; 5 is a lead terminal that connects the lead wire 4; 6 is a post conductor connected to the lead terminal 5; 7 is an extension lead portion that covers the post conductor 6; Reference numeral 8 denotes a protection tube made of a metal material, and the opening 8a at one end of the tube is sealed with a plate of good thermal conductivity such as stainless steel, copper, silver, etc., which is brought into contact with the object to be measured (not shown). In addition, the extension lead part 7 is inserted into the opening 8b on the other end side, and is fixed and supported by an adhesive 10. Further, the resistance element 1 is arranged so that the axis of the winding core 2 is perpendicular to the flat surface 9a of the heat-sensitive part 9, and is fixed by filling the space between it and the protection tube 8 with the same adhesive 10 as described above. ing.

感熱部９に伝わつた熱が接着剤１０を径てさらに
抵抗素子１に伝わつて一定温度になるまでかなり
の時間がかかる欠点があつた。 Since the conventional resistance temperature detector is configured as described above, when the heat sensitive part 9 is brought into contact with the object to be measured,
There was a drawback that the heat transmitted to the heat sensitive part 9 was further transmitted to the resistance element 1 through the adhesive 10, and it took a considerable amount of time to reach a constant temperature.

量がさらに多くなる欠点があつた。 In addition, if the length L 1 of the extension lead portion 7 is inserted, that is, the length L 1 of the support portion, is shorter than the length L 0 of the protection tube 8, and the tube is bent or detached at this portion. However, there were drawbacks such as the lead wire 4 being cut. Therefore, by increasing the length L 0 of the protection tube 8, the insertion portion of the extension lead portion 7 can be deepened and the length L 1 of the support portion can be increased. The drawback was that the amount used was even greater.

This idea was made in order to eliminate the above-mentioned drawbacks, and the axis of the winding core of the resistance element is made parallel to and close to the heat-sensing part to speed up the transfer of heat from the heat-sensing part. To provide a temperature measuring resistor which is arranged so as to shorten the temperature measuring time and to enable the extension lead part to be inserted deeply into the protective tube, so that the supporting part is elongated and formed so as to be able to be firmly supported. This idea will be explained below.

As explained above, this idea seals the opening at one end of the protective tube with a heat-sensitive part made of a plate with good thermal conductivity, while forming a resistance element by winding a platinum resistance wire around the winding core. However, since the axis of the winding core of this resistance element is arranged parallel to and close to the heat-sensing part, the heat of the heat-sensing part is quickly transferred to the resistance element, and the time required for measurement can be shortened. In addition, the extension lead connected to the platinum resistance wire can be deeply inserted into the opening at the other end of the protection tube, and since the protection tube is filled with adhesive and sealed and fixed, the extension lead The support part is long and will not bend or come off, so it will not be damaged. Furthermore, it has the advantage that the amount of adhesive used is extremely small compared to conventional methods.
