Description

  The present invention relates to a surface temperature sensor for measuring the surface temperature of an object to be measured.

  In many cases, the surface temperature sensor uses a very large number of surface temperature sensors for one object to be measured in order to measure the temperature distribution of the object to be measured. Moreover, it is necessary to fix the surface temperature sensor on the object to be measured in order to continuously measure the same part of the object to be measured with the same measurement conditions.

  Therefore, conventionally, the surface temperature sensor is fixed to the object to be measured so as to cover the surface temperature sensor with an adhesive tape. Alternatively, an adhesive is applied to the anti-thermocouple surface of any of the insulating sheets, and the surface temperature sensor is fixed by interposing the adhesive between the object to be measured.

  However, in order to fix a number of surface temperature sensors with adhesive tape, the adhesive tape is prepared to be cut to the specified size for the number of surface temperature sensors, and the surface temperature sensor is fixed to the object to be measured with the adhesive tape. After that, since the tape was peeled off from the surface temperature sensor, it took time to fix and peel the surface temperature sensor, and there was a problem that the work efficiency was poor. Also, in the case of an adhesive, the adhesive is applied to the antithermocouple surface of any insulating sheet to fix the surface temperature sensor to the object to be measured, and after peeling, adheres to the insulating sheet and the object to be measured. As the adhesive is removed, it takes time to fix and peel the surface temperature sensor, and there is a problem that the work efficiency is poor.

  In Patent Document 1 below, in order to solve this problem, a thermocouple is held between a pair of insulating tapes through an adhesive layer, and one of the insulating tapes is removed in the vicinity of the junction of the thermocouple. Thus, it has been proposed to partially expose the adhesive layer and fix the thermocouple to the object to be measured at the exposed portion of the adhesive layer.

  However, in Patent Document 1, since the thermocouple junction is exposed from the insulating tape and attached to the object to be measured, noise is introduced into the temperature measurement, and the thermocouple is damaged when peeled off from the object to be measured. There was a bug.

Japanese Patent Laid-Open No. 10-2805

  The present invention has been made in order to solve the above-described problems, and the object of the present invention is to be able to be easily fixed to the object to be measured and even after peeling from the object to be measured. It is to provide a surface temperature sensor that does not cost.

  In order to achieve the above object, a surface temperature sensor according to claim 1 of the present invention is a surface temperature sensor in which a thermocouple is sandwiched between two insulating sheets, and the insulating property of at least one of the insulating sheets. The thermocouple surface of the sheet has adhesive strength, and the antithermocouple surface of any one of the insulating sheets has repeated adhesive strength.

  A surface temperature sensor according to a second aspect of the present invention is the surface temperature sensor according to the first aspect, wherein the insulating sheet is a heat-resistant insulating sheet.

  A surface temperature sensor according to a third aspect of the present invention is the surface temperature sensor according to the first or second aspect, wherein a release paper is provided on the side of the insulating sheet where the antithermocouple surface repeatedly has adhesive force. It is characterized by sticking.

  The present invention has the following effects.

  That is, in the surface temperature sensor having the above-described configuration, since the thermocouple surface of at least one of the insulating sheets has adhesiveness, both surfaces of the insulating sheet are sandwiched between the thermocouples. When a surface temperature sensor is manufactured by bonding together, it is not necessary to apply an adhesive between the insulating sheet and the thermocouple, and the thermocouple can be easily bonded between the insulating sheets.

  In addition, the anti-thermocouple surface of any one of the insulating sheets that make up the surface temperature sensor has repeated adhesive strength, so that it adheres when the surface temperature sensor is fixed to the object to be measured. There is no need to pre-cut the tape, and there is no need to apply an adhesive between the insulating sheet and the object to be measured. The temperature sensor can be easily fixed. In addition, since the anti-thermocouple surface of the insulating sheet bonded to the object to be measured has repeated adhesive force, it is not necessary to wipe off the adhesive surface of the object to be measured after peeling, and to another object to be measured. Since it can be fixed, the efficiency of measurement work can be improved.

  Furthermore, if the insulating sheet is a heat-resistant insulating sheet, a high-temperature object can also be measured.

  Furthermore, since the release paper is stuck on the antithermocouple surface side of the insulating sheet where the antithermocouple surface repeatedly has adhesive force, it is possible to prevent foreign matter from adhering before use.

In the surface temperature sensor according to the present invention, (1) is a front view and (2) is a plan view.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows one embodiment of a surface temperature sensor according to the present invention, wherein (1) is a front view and (2) is a plan view.

  As shown in FIG. 1, the surface temperature sensor 1 according to the present invention includes a thermocouple 10, two insulating sheets 20, and a release paper 30.

  The thermocouple 10 is a K thermocouple that is frequently used as an industrial thermocouple, and measures the temperature by the thermoelectromotive force generated by the temperature difference between the connection point 11 of the two types of metal and the output terminal 12 side. As the two kinds of metals, platinum and platinum rhodium, chromel and alumel, copper and constantan and the like are used.

  The insulating sheet 20 is composed of two sheets (20A, 20B) so as to sandwich the thermocouple 10 therebetween. One insulating sheet 20A is coated with an adhesive 23 so as to have adhesive force on the thermocouple surface 21A. In addition, although the adhesive agent is not apply | coated to the thermocouple surface 21B of the other insulating sheet 20B, the adhesive agent may be apply | coated. On the contrary, the adhesive may not be applied to the thermocouple surface 21A of one insulating sheet A, but the adhesive may be applied to the thermocouple surface 21B of the other insulating sheet 20B.

  Furthermore, an adhesive 24 having repeated adhesive strength is applied to the anti-thermocouple surface 22A of one insulating sheet 20A, and a release paper 30 is adhered so as to cover the adhesive 24 having repeated adhesive strength. ing. Even in this case, the adhesive 24 having repeated adhesive strength is not applied to the antithermocouple surface 22A of one insulating sheet 20A, and the antithermocouple surface 22B of another insulating sheet 20B is repeatedly applied. An adhesive 24 having adhesive strength may be applied, and a release paper 30 may be attached so as to cover the adhesive 24 having repeated adhesive strength.

  As a material of the insulating sheet 20, a polyimide amide resin or the like that has high insulation and good heat resistance is used.

  As a material of the release paper 30, cellophane or the like that is easily peeled off is used.

  In the above description, the adhesive 23 having adhesive force is applied to the thermocouple surface 21A of one insulating sheet 20A, and the adhesive 24 having repeated adhesive force is applied to the counter thermocouple surface 22A. Although it has been described that the release paper 30 is stuck so as to cover the adhesive 24 having repeated adhesive strength, an adhesive sheet that is commercially available as such may be used. For example, (not shown for public order and moral violations) can be used.

  As described above, the surface temperature sensor 1 according to the present application has two insulating sheets (20A, 20B) because the adhesive 23 having adhesive force is applied to the thermocouple surface 21A of one insulating sheet 20A. When manufacturing the surface temperature sensor 1 with the thermocouple 10 sandwiched therebetween, it is not necessary to apply an adhesive between the thermocouple surface 21A of the insulating sheet 20A and the thermocouple 10, and the insulating sheet (20A, 20B) can be easily formed. It becomes possible to stick the thermocouple 10 to.

  Moreover, since the adhesive 24 having repeated adhesive force is applied to the anti-thermocouple surface 22A of one insulating sheet 20A, the surface temperature sensor 1 is fixed by attaching the anti-thermocouple surface 22A to the object to be measured. This makes it possible to improve the efficiency of measurement work.
