Description

  The present invention relates to a thin thermometer that is optimal for measuring a temperature by being sandwiched between objects to be measured.

  A thin thermometer formed in a band shape is used when measuring the temperature at the time of pressurization in a press, the temperature between layers such as plywood, and the temperature of an electric carpet or the like.

  Such a thin thermometer includes a temperature measuring unit that measures temperature, or a temperature sensing unit that includes a temperature measuring unit and that is thinly formed to sense the temperature of the temperature measuring object. Depending on the size, it is required to make the portion other than the temperature measuring portion or the temperature sensing portion thin and to form a belt shape.

  As a thin thermometer having a thickness of 1 mm or less, a thin thermometer has been proposed in which a temperature sensor element such as a thermocouple is bonded from both sides with an insulating tape or an insulating film (for example, Patent Documents). 1 or 2).

  However, although these thin thermometers are thin, they are soft, such as an insulating tape or an insulating film, and have a problem in operability and durability due to a structure in which a temperature sensor element such as a thermocouple is sandwiched.

  In particular, if the length of the band-shaped part is 300 mm or more, even if you try to place the temperature measuring part or the temperature sensing part in the place where you want to measure, holding the part far from the temperature measuring part or the temperature sensing part, The part is too soft, and the temperature measuring part and the temperature sensing part cannot be arranged at the place to be measured. For this reason, there is no choice but to place the temperature measuring part or the temperature sensing part in the place where the measurement is desired, and if the place where the measurement is desired is hot, the danger increases and the arrangement becomes impossible.

  In addition, there is a problem of durability such as damage to a sensor element such as a thermocouple due to the pressure from the temperature measurement object when sandwiched between the temperature measurement objects.

  Therefore, the present invention has been made in view of the above problems, and the problem is that the temperature sensor element can be reinforced and the rigidity can be improved, thereby improving the durability of the temperature sensor element. An object of the present invention is to provide a thin thermometer capable of improving the operability when a temperature measuring unit and a temperature sensing unit are arranged at a measurement site.

  A thin thermometer according to the present invention for solving the above-described problems includes a temperature sensor element, a reinforcing member having rigidity higher than that of the temperature sensor element, and a joining member joined to the reinforcing member. The temperature sensor element is disposed along the length direction of the temperature sensor element, and the temperature sensor element and the reinforcing member are integrated by the joining member to be formed into a band-shaped band-shaped body.

  The reinforcing member here may be formed of a material having a higher strength than the member constituting the temperature sensor element, but the width and the plate thickness are increased even with a material having a lower strength than the member constituting the temperature sensor element. Thus, it may be formed so as to be more rigid than the temperature sensor element.

  For example, when the temperature sensor element is composed of a thermocouple, stainless steel is a member having higher strength than a thermocouple wire (metal material such as alumel or chromel) or a covering member (fluororesin or polyimide resin) of the thermocouple. A metal such as steel is desirable because it can be easily processed, and the rigidity as a reinforcing member is increased.

  The joining member is a member that integrates the temperature sensor element and the reinforcing member, and is formed of stainless steel, heat resistant resin, or the like similar to the reinforcing member, or an adhesive tape.

  In addition, if the maximum thickness of the band-shaped strip formed by the temperature sensor element and the reinforcing member is 1 mm or less, preferably 0.5 mm or less, more preferably 0.3 mm or less, the temperature is further increased. It can be measured accurately. If the thickness is greater than 1 mm, the temperature of the temperature sensing element may not be accurately transmitted to the temperature sensing section of the temperature sensor element, or the temperature of the temperature sensing object may be excessively widened to change the temperature. Occur.

  According to this configuration, the reinforcing member is disposed along the length direction of the temperature sensor element, and the temperature sensor element and the reinforcing member are integrally formed by the joining member to form a band shape, thereby reducing the thickness of the thin thermometer. The rigidity of the thin thermometer can be improved without increasing the thickness. As a result, the temperature sensor element of the thin thermometer can be prevented from being damaged and the durability can be improved, and the operability when placing the temperature measuring part and the temperature sensing part at the measurement site can be improved. it can.

  Moreover, since the temperature sensor element and the reinforcing member are integrated by the joining member, it is possible to prevent the temperature sensor element and the reinforcing member from falling apart during use.

  In the thin thermometer described above, the reinforcing member is arranged side by side in the width direction of the temperature sensor element, and the temperature sensor element is formed to have a thickness equal to or less than the thickness of the reinforcing member. If configured, the temperature sensor element is not directly applied to the temperature sensor element even if the temperature sensor element is sandwiched between the temperature sensor element, preventing damage to the temperature sensor element and improving durability. it can.

  For example, when the temperature sensor element is composed of a thermocouple, each thermocouple wire of the thermocouple is formed to a thickness equal to or less than the thickness of the reinforcing member. When a covering member that covers the thermocouple is provided, the covering member is preferably an insulating member, and the covering member may be formed thicker than the reinforcing member.

  In addition, in the thin thermometer described above, the reinforcing members are disposed on both sides in the width direction of the temperature sensor element, and a pair of front and back connecting members connect the reinforcing members on both sides, and the temperature If the sensor elements are sandwiched and arranged, the reinforcing members are arranged on both sides of the temperature sensor elements, whereby the strength of the thin thermometer can be improved.

  Furthermore, in the thin thermometer described above, a temperature measuring part provided at a tip part of the temperature sensor element is fixed to the joining member arranged at a tip part of the reinforcing member to sense the temperature of the temperature measuring object. If it comprises so that the temperature sensing part to warm may be formed, the temperature measurement part of a temperature sensor element can be reinforced. For example, stainless steel (SUS) is preferable as the bonding member forming the temperature-sensitive portion from the viewpoint of strength and heat uniformity.

  The above-mentioned thin thermometer does not need to improve the strength and durability of the temperature sensor element itself. For example, when the temperature sensor element is constituted by a thermocouple, the thermocouple wire constituting the thermocouple is thinned. Thus, the metal material used for the thermocouple wire can be reduced, and the manufacturing cost can be reduced.

  According to the present invention, the reinforcing member is disposed along the length direction of the temperature sensor element, and the temperature sensor element and the reinforcing member are integrated and formed into a band shape by the joining member, thereby reducing the thickness of the thin thermometer. The rigidity can be improved without increasing the thickness. Thereby, breakage of the temperature sensor element and the like can be prevented, durability can be improved, and operability when the temperature measuring unit and the temperature sensing unit are arranged at the measurement site can be improved.

It is a perspective view which shows the strip | belt-shaped body of the thin-type thermometer of 3rd embodiment which concerns on this invention.

  Hereinafter, a thin-type thermometer according to an embodiment of the present invention will be described with reference to the drawings. In this embodiment, a thin thermometer using a thermocouple as a temperature sensor element will be described as an example. However, the present invention is not limited to this, and can be applied to, for example, a resistance temperature detector. . In addition, as a thermocouple, the type K using chromel for the positive electrode and alumel for the negative electrode will be described as an example. However, the present invention is a type E using chromel for the positive electrode and constantan for the negative electrode, The present invention can be applied to various types of thermocouples such as rhodium alloy (rhodium content 30%) and type B using a platinum rhodium alloy (rhodium content 6%) at the negative electrode.

  In addition, the dimensions of the drawings are changed so that the configuration can be easily understood, and the ratios of the thickness, width, length, etc. of each member and each part do not necessarily match the ratio of what is actually manufactured. . In the drawings, the length direction of the temperature sensor element is the x direction, the width direction is the y direction, and the thickness direction is the z direction.

  A thin thermometer 1 according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1, the thin thermometer 1 includes a band-like body 2 sandwiched between temperature-measuring bodies, a handle 3 held by a measurer, and a signal line 4 connected to a measurement device (not shown). In this embodiment, as shown in FIG. 3, a press machine P is assumed as a temperature-measured body.

  As shown in FIGS. 1 and 2, the band-like body 2 has a dimension in the length direction x (hereinafter referred to as length) L1, a dimension in the width direction y (hereinafter referred to as width) b1, and a thickness direction. It is formed in a thin band shape having a dimension z (hereinafter referred to as thickness) d1, and includes a thermocouple (temperature sensor element) 5, a reinforcing member 6, a first joining member 7, and a second joining member 8. In this embodiment, the length L1 is 500 mm, the width b1 is 11 mm, and the thickness d1 is 0.3 mm.

  The thickness d1 is the maximum thickness of the strip 2 and in this embodiment is the portion where the tip of the strip 2 and the first joining member 7 are located. The dimension of this strip | belt-shaped body 2 is an example to the last, and this invention is not limited to this.

  Since the length L1 of the belt-like body 2 of this embodiment is 300 mm or more, as described above, it is necessary to reinforce without increasing the thickness d1. Therefore, the belt-like body 2 arranges the reinforcing member 6 along the length direction x of the thermocouple 5 and integrates the thermocouple 5 and the reinforcing member 6 with the first joining member 7 and the second joining member 8. ,It is formed.

  Further, in this embodiment, the reinforcing members 6 are arranged on both sides of the thermocouple 5 in the width direction y. The thickness d2 of the thermocouple wires 5a to 5c of the thermocouple 5 is formed to be equal to or less than the thickness d3 of the reinforcing member 6, and the thermocouple 5 is sandwiched between the pair of front and back first joining members 7. Is done.

  The thermocouple 5 includes a thermocouple wire 5a formed in a belt shape with chromel, a thermocouple wire 5b formed in a belt shape with alumel, and a thermocouple wire 5c formed in a belt shape with chromel. In this thermocouple 5, the thermocouple element 5a and the thermocouple element 5b are arranged side by side, the thermocouple element 5c is arranged and joined so as to connect the end parts thereof, and the end of the thermocouple element 5b The thermocouple element 5b and the thermocouple element 5c overlap each other, and a hot junction (temperature measuring unit) 9 is provided.

  The thermocouple 5 is constituted by forming the thermocouple strands 5a to 5c formed in a strip shape as described above, and a portion of the thermocouple strands 5a and 5b is covered with the covering member 10, so that It is formed in a belt shape. The covering member 10 is preferably a highly insulating member, such as a fluororesin or a polyimide resin.

  The thermocouple wires 5a and 5b can be protected by covering a part of the thermocouple wires 5a and 5b with the covering member 10, and the thermocouple wire 5a and the thermocouple wire 5b are connected to the heat contact 9 It is possible to prevent contact with other than the above. The covering member 10 does not cover a portion where the thermal contact 9 is formed, but may cover the portion.

  The thickness d2 of each of the thermocouple strands 5a to 5c of the thermocouple 5 is set to a value equal to or smaller than the thickness d1 of the strip 2 and more preferably equal to or smaller than the thickness d3 of the reinforcing member 6 described later. When the thickness d2 of the thermocouple 5 becomes a value equal to or less than the thickness d3 of the reinforcing member 6, even if the belt-like body 2 is sandwiched between the temperature-measuring bodies, the temperature-measuring body contacts the reinforcement member 6, And the thermocouple 5 are not in direct contact with each other, and it is possible to prevent the thermocouple 5 from being subjected to pressure from the temperature measurement object. In this embodiment, the thickness d2 of each of the thermocouple wires 5a to 5c is 0.05 mm.

  The thickness d4 of the covering member 10 that covers the thermocouple wires 5a to 5c is not particularly limited with respect to the thickness d2 of the thermocouple wires 5a to 5c of the thermocouple 5, and the thermocouple wires 5a It suffices to be thicker than the thickness d2 of ˜5c. For example, if the reinforcing member 6 is formed thicker than the thickness d3, the thermocouple wires 5a to 5c can be more securely protected. In this embodiment, the thickness d4 of the covering member 10 is 0.2 mm.

  The thermocouple 5 may be provided with a thermal contact 9 at the tip of the thermocouple wire 5a using a thermocouple wire 5c formed of alumel. Further, by using thermocouple wires formed of two different metals, either one may be bent and contacted with the other to form a thermal contact, or both may be bent to form a thermal contact.

  In addition, although the thermocouple wires 5a to 5c are formed in a band shape, they can be formed as thin wires, for example, as thin wires or threads. If the thermocouple strands 5a to 5c are formed so thin, or the width b2 of the thermocouple strands 5a and 5b is narrowed, the material used to form the thermocouple strands 5a and 5b can be reduced. Manufacturing costs can be reduced.

The reinforcing member 6 is made of a metal material such as stainless steel (hereinafter referred to as SUS) and is formed in a thin strip shape. The reinforcing members 6 are arranged on both sides of the thermocouple 5 in the width direction y so that the thermocouple 5 is located between the reinforcing members 6. The reinforcing member 6 preferably has sufficient strength and flexibility even if the thickness d3 is reduced, and a metal material such as SUS is desirable.

  The thickness d3 of the reinforcing member 6 is formed to be thicker than the thickness d2 of the thermocouple 5 as described above. In this embodiment, the thickness d3 of the reinforcing member 6 is 0.15 mm. Thus, it is preferable that the reinforcing member 6 has sufficient strength and flexibility even with a thickness of 0.2 mm or less.

  The width b3 of the reinforcing member 6 is preferably at least one third of the width b1 of the strip 2 in consideration of the feeling of use of the strip 2 and is set to 3.2 mm in this embodiment. If the width b3 of the reinforcing member 6 is smaller than one third, the rigidity of the strip 2 may be lowered.

  In this embodiment, the two reinforcing members 6 are arranged on both sides of the thermocouple 5 in the width direction y. However, if the rigidity of the belt-like body 2 is insufficient, the reinforcing member 6 is added and the rigidity is increased. May be improved. For example, the thermocouple element 5a and the thermocouple element 5b of the thermocouple 5 are respectively covered with the covering member 10, and an additional reinforcing member is provided so as to be positioned between the thermocouple element 5a and the thermocouple element 5b. You may arrange. Further, the rigidity may be increased by forming the reinforcing members 6 in layers or by increasing the thickness d3 of the reinforcing members 6.

  Similar to the reinforcing member 6, the first joining member 7 is formed in a thin plate shape with SUS. The first joining member 7 is a place excluding the tip of the reinforcing member 6, and the pair of front and back first joining members 7 sandwich the thermocouple 5 provided between the reinforcing members 6 from both sides in the thickness direction z. And is joined to the reinforcing member 6 by spot welding (resistance welding) or the like.

  The thickness d5 of the first joining member 7 was 0.065 mm. In this way, even if the pair of front and back first joining members 7 are joined to the reinforcing member 6, the thickness d 5 of the first joining member 7 is made larger than that of the reinforcing member 6 so that the maximum thickness d 1 of the strip 2 is obtained. Also make it thinner.

  Similar to the reinforcing member 6, the second joining member 8 is formed in a thin plate shape with SUS. The second joining member 8 is disposed at the tip of the reinforcing member 6 and the thermocouple 5 is fixed. Then, the thermocouple 5 is fixed to the second bonding member 8, so that the temperature sensing part 12 that senses the temperature of the temperature measurement object is obtained. The thermocouple 5 and the second joining member 8 are fixed by spot welding, soldering, adhesive, silver brazing or the like.

  When the thickness d6 of the second bonding member 8 is reduced, the durability of the tip of the strip 2 is reduced. On the other hand, when the thickness is increased, the temperature of the measured object is accurately transmitted to the thermal contact 9 of the thermocouple 5. It will not be done. Therefore, the thickness in consideration of durability and heat conduction is preferable. In this embodiment, the thickness d6 of the second joining member 8 is set to 0.15 mm, similarly to the thickness d3 of the reinforcing member 6.

  The temperature measuring part protection member 11 is a member that protects the thermal contact 9 of the thermocouple 5 and prevents the thermal contact 9 from being detached from the second joining member 8. Like the reinforcing member 6, it is a thin plate like SUS. Formed. The temperature measuring part protection member 11 is formed so as to fill the space between the reinforcing members 6 and is joined to the second joining member 8 by spot welding or the like.

The thickness d7 of the temperature measuring part protection member 11 was set to 0.065 mm, similarly to the thickness d5 of the first joining member 7. Since this portion becomes the temperature sensing portion 12 at the tip of the belt-like body 2, it is preferable that the belt-like body 2 be formed so as to be as uneven as possible so that the belt-like body 2 can be easily inserted into the temperature-measured body. Therefore, in consideration of the thickness d2 of each thermocouple element 5a to 5c of the thermocouple 5, the thickness d2 of each thermocouple element 5a to 5c of the thermocouple 5 and the thickness d7 of the temperature measuring portion protection member 11 are considered. It is preferable that the combined thickness is approximately the same as the thickness d3 of the reinforcing member 6.

  If the thickness d8 of the temperature sensing part 12 formed by sandwiching the thermal contact 9 of the thermocouple 5 is formed as thin as possible with the second joining member 8 and the temperature measuring part protection member 11, an accurate temperature can be measured. it can. If the thickness d8 of the temperature sensitive part 12 is 1 mm or less, preferably 0.5 mm or less, more preferably 0.3 mm or less, the temperature can be measured more accurately. In this embodiment, the thickness d8 of the temperature sensing part 12 is 0.3 mm.

  Next, the manufacturing method of the thin thermometer 1 of 1st embodiment is demonstrated. First, a thin strip-shaped thermocouple element 5a and a thin plate-shaped thermocouple element 5c are formed from chromel, and a thin strip-shaped thermocouple element 5b is formed from alumel. Next, it arranges in the state which provided the space | interval between the thermocouple strand 5a and the thermocouple strand 5b. Next, the thermocouple element 5c is overlapped on the tip of the thermocouple element 5a and the thermocouple element 5b, and is joined to each by spot welding. Next, a part of the thermocouple wires 5a and 5b is covered with the covering member 10 to complete the thin strip-like thermocouple 5.

  Next, a thin strip-shaped reinforcing member 6, a first joining member 7, a second joining member 8, and a temperature measuring part protection member 11 on a thin plate are formed from SUS. Next, the reinforcing members 6 are arranged along the length direction x of the thermocouple 5 on both sides in the width direction y of the thermocouple 5.

Next, the second bonding member 8 is disposed at the distal end portion of the reinforcing member 6, and the thermocouple 5 is connected to the second bonding member 8 so that the thermal contact 9 of the thermocouple 5 is disposed on the second bonding member 8. A portion that is not covered with the covering member 10 is spot-welded. And the temperature sensing part protection member 11 is spot-welded to the 2nd joining member 8, and the temperature sensing part 12 is completed.

  Next, a plurality of front and back pairs of first joining members 7 are arranged so as to sandwich the thermocouple 5 and spot-welded to the reinforcing member 6. Thereby, the thermocouple 5 and the reinforcing member 6 are integrated, and the thin strip-shaped body 2 is completed.

  When manufacturing the strip 2, the maximum thickness d 1 of the strip 2, that is, in this embodiment, the thickness of the portion where the pair of front and back first joining members 7 are joined to the reinforcing member 6 is also sensed. Similarly to the thickness d8 of the warm portion 12, if the thickness is formed to be 1 mm or less, preferably 0.5 mm or less, more preferably 0.3 mm or less, the temperature can be measured more accurately. When the thickness d1 is greater than 1 mm, there is a problem in that the temperature measurement object opens too much and the temperature changes.

  As described above, the thin thermometer 1 easily forms the reinforcing member 6, the first joining member 7, and the second joining member 8 by SUS having high workability, and thereby, the thermocouple 5 and the reinforcing member 6. Can be easily integrated. For this reason, manufacturing cost can be reduced.

  Next, an operation for measuring the temperature of a temperature-measured body such as a press using the thin thermometer 1 will be described with reference to FIG. As shown in FIG. 3A, when measuring the temperature at the back of the press machine P, the handle 2 of the thin thermometer 1 is held and the strip 2 is inserted between the press machines P. And if the handle 3 is pushed as it is, the temperature sensing part 12 can be arrange | positioned in the back of the press machine P. FIG.

  As described above, the reinforcing members 6 are arranged on both sides of the thermocouple 5, and the thermocouple 5 and the reinforcing member 6 are integrally formed by the first joining member 7 and the second joining member 8 to be formed into a belt shape. Since the strength is increased without increasing the thickness d1 of the thermometer 1, the temperature sensing unit 12 can be easily located at a place where measurement is desired.

  On the other hand, since the reinforcing member 6 has appropriate flexibility, it is possible to prevent the belt-like body 2 from being easily broken when the thin thermometer 1 is operated. Moreover, since the reinforcing member 6 is arrange | positioned on both sides of the thermocouple 5, and they are integrated by the 1st joining member 7 and the 2nd joining member 8, it prevents that the thermocouple 5 and the reinforcing member 6 fall apart. Can do.

  As described above, the reinforcing members 6 are arranged on both sides of the thermocouple 5, and the thermocouple 5 and the reinforcing member 6 are integrally formed by the first joining member 7 and the second joining member 8 to be formed into a belt shape. The operability of the thermometer 1 can be improved.

  In addition, the corners of the temperature-sensitive part 12 formed by the reinforcing member 6 and the second joining member 8 are rounded, or the temperature-sensitive part 12 is shaped like a circle, an ellipse, a triangle, etc. If it forms so that it may become narrow, the operativity at the time of arrange | positioning the temperature sensing part 12 to a measurement site | part can be improved.

  In addition, as shown in FIG. 3 (b), when the press P is pressed and the temperature is measured in this state, the thickness d1 of the strip 2 of the thin thermometer 1 is sufficiently thin. Temperature can be measured. In addition, even when pressed from both sides by the press machine P at this time, since the thickness d2 of the thermocouple 5 is less than the thickness d3 of the reinforcing member 6, the pressure of the press machine P is not applied to the thermocouple 5. Further, breakage of the thermocouple 5 can be suppressed.

  As shown in FIGS. 3A and 3B, even if the thin thermometer 1 is used, the reinforcing members 6 are arranged on both sides of the thermocouple 5, and the first joining member 7 and the second joining member 8. Thus, the thermocouple 5 and the reinforcing member 6 are integrated into a band shape, so that the strength can be improved without increasing the thickness d1 of the thin thermometer 1. Thereby, damage to the thermocouple 5 of the thin thermometer 1 can be prevented, and durability can be improved.

  In this embodiment, the reinforcing member 6, the first joining member 7, and the second joining member 8 are made of SUS. However, for example, the second joining member 8 is made of a metal material having high heat uniformity and is reinforced. The member 6 and the first joining member 7 may be formed of a heat resistant resin or the like. Moreover, you may form with the adhesive tape of the 1st joining member 7, etc.

  Next, a thin thermometer according to a second embodiment of the present invention will be described with reference to FIG. The belt-like body 21 of the thin thermometer 20 has the reinforcing members 6 on both sides of the thermocouple 5 in the width direction y, and the first joining members 22 are alternately arranged on the front and back sides. 6 is formed integrally.

  Then, the thermocouple 5 is fixed to the second joining member 8 disposed at the distal end portion of the band-shaped body 21, that is, the distal end portion of the reinforcing member 6, and the temperature sensing portion 23 is formed.

  As described above, even when the first bonding members 22 are alternately arranged on the front and back sides, the thermocouple 5 and the reinforcing member 6 can be integrated to form the band-shaped band 21.

  According to this configuration, since the first joining members 22 are alternately arranged, the thickness d9 of the portion where the first joining members 22 are located is made thinner than the thickness d1 of the first embodiment. Can do.

  Next, a thin thermometer according to a third embodiment of the present invention will be described with reference to FIG. The strip 31 of the thin thermometer 30 has the reinforcing member 6 disposed on one side in the width direction y of the thermocouple 5, and the plate-like first joining member 32 is bent so as to sandwich the thermocouple 5. The thermocouple 5 and the reinforcing member 6 are formed integrally with each other.

  According to this configuration, since the number of members is reduced, the cost can be suppressed. Moreover, a softness | flexibility can be improved more by making the reinforcement member 6 into one side.

  For example, in the first embodiment, the first joining member 22 of the second embodiment can be used instead of the first joining member 7. Moreover, it can also be set as the structure which does not provide the temperature measuring part protection member 11. FIG.

  In addition, the reinforcing member 6 is not arranged side by side in the width direction y of the thermocouple 5 as in the above embodiment, but the thickness of the belt-like body is increased, but the third member is overlapped in the thickness direction z. The thermocouple 5 and the reinforcing member 6 can be integrated to form a belt-like shape by winding the first joining member 32 or the adhesive tape of the embodiment.

  However, when the number of the reinforcing members 6 is one, the durability of the thermocouple 5 becomes low, or when the number of the reinforcing members 6 is two and the thermocouples 5 are integrated with the thermocouple 5 interposed therebetween, the flexibility becomes low. Or Therefore, preferably, the reinforcing member 6 is arranged in the width direction y of the thermocouple 5.

  The thin thermometer of the present invention has a reinforcing member disposed along the length direction of the temperature sensor element, and the temperature sensor element and the reinforcing member are integrally formed by a joining member to form a belt shape. Without increasing the thickness, the strength can be improved, the temperature sensor element can be prevented from being damaged, etc., and the durability can be improved. Since the operability can be improved, it can be used to measure the temperature particularly by being sandwiched between the objects to be measured.
