The excess wiring 8 is stored in a space between the wiring storage unit 35 and the back surface of the thermometer body 3. Further, the thermometer body 3 is fixed to the pedestal 6 by inserting screws 40 into the screw holes 15 of the thermometer body 3 and embedding the screws 40 in the pedestal 6. Thus, the temperature measuring body 10 is disposed on the inner curved surface side of the covering member 5, and the thermometer main body 3 is disposed on the outer curved surface side of the covering member 5. As described above, the thermometer main body 3, the wiring 8, and the temperature measuring body 10 can be easily attached. The extra length of wiring 8 can be stored compactly in the wiring storage section 35 and does not get in the way.

  Next, a method for attaching the above-described piping thermometer 1 will be described. The inside of the coverings 21 and 22 is opened, and as shown in FIG. 1, coverings 21 and 22 are arranged around a circular pipe 2 arranged in a substantially vertical direction, and the pipe 2 is covered with the coverings 21 and 22. The inside of the coverings 21 and 22 is closed so as to be sandwiched between the inner curved surfaces. As a result, the outer peripheral surface of the pipe 2 is covered with the covering member 5. As shown in FIGS. 20 and 21, a slight gap is formed between the outer peripheral surface of the pipe 2 and the inner curved surface of the covering member 5. The temperature measuring body 10 is sandwiched between the groove 38 and the outer peripheral surface of the pipe 2 and is in close contact with the outer surface of the pipe 2. And the surplus part 31 is affixed on the to-be-adhered surface 32, and the coverings 21 and 22 are mutually joined. Thereby, the thermometer 1 for piping is reliably attached to piping, and the thermometer 10 is firmly attached and fixed to the outer peripheral surface of the piping 2. Since the covering body 22 is formed of an elastic material, the groove 38 is pushed by the temperature measuring body 10 and is recessed to the back, and the repulsive force is pushed in the direction of pushing the pipe 2 from the groove 38 to the temperature measuring body 10. Is given. Therefore, the state in which the temperature measuring body 10 is in close contact with the outer surface of the pipe 2 is reliably maintained. As described above, the temperature measuring body 10 can be easily and reliably attached to a desired position where the temperature is measured only by closing the inside of the coverings 21 and 22 and attaching the surplus portion 31 to the adherend surface 32. . Since the thermometer body 3 is integrally provided in advance on the pedestal 6, it is not necessary to fix the thermometer body 3 separately when the pipe thermometer 1 is attached to the pipe 2, and the workability is good. Further, the portion where the surplus portion 31 is pasted is not conspicuous and does not feel complicated in appearance.

  Next, as shown in FIG. 22, heat insulating materials 46 and 47 are wound around the upper and lower portions of the thermometer 1 for piping, respectively. The heat insulating materials 46 and 47 are wound to the vicinity of the covering member 5 so that the pipe 2 is continuously covered by the heat insulating material 46, the covering member 5 and the heat insulating material 47. Then, tapes 50 and 51 are wound around the boundary portion between the heat insulating material 46 and the covering member 5 and the boundary portion between the heat insulating material 47 and the covering member 5, respectively, so that the heat insulating material 46 and the covering member 5, the heat insulating material 47 and the covering member 5. And fix them together.

  When the solar cell unit 13 is irradiated with a light beam having a predetermined illuminance or higher, electric power is generated in the solar cell unit 13, and the pipe thermometer 1 is operated by this electric power. The resistance value of the temperature measuring element 10 changes according to the temperature of the outer peripheral surface of the pipe 2, and the resistance value is sent to the processing circuit (not shown) of the thermometer main body 3 through the wiring 8. A processing circuit (not shown) converts the resistance value of the temperature sensing element 10 into a temperature, and displays the temperature on the display unit 12 as a digital value. Thus, since the thermometer 1 for piping is operated with the electric power from the solar cell part 13, it is not necessary to connect the wiring for electric power supply from the outside, and the thermometer 1 for piping can be attached compactly. Also, it does not feel complicated in appearance.

  Moreover, since the outer peripheral surface of the pipe 2 is covered with the highly heat-insulating covering member 5, it is possible to prevent heat radiation from the place where the temperature measuring element 10 is disposed, and the temperature of the outer surface of the pipe 2, that is, A temperature close to the temperature of the fluid in the pipe 2 can be accurately measured. Therefore, the temperature change of the fluid in the pipe 2 can be monitored with high accuracy. Since the thermometer main body 3 is attached so that the numbers and symbols indicating the temperature of the display unit 12 are written horizontally in a substantially horizontal direction, it is easy to read the displayed temperature.

  When removing the pipe thermometer 1 from the pipe 2, first, the tapes 50 and 51 are peeled off, and then the surplus portion 31 is peeled off from the adherend surface 32 and the inside of the coverings 21 and 22 is opened. Thus, the pipe thermometer 1 can be easily detached from the pipe 2.

  According to the pipe thermometer 1, the temperature measuring body 10 can be reliably attached to the outer peripheral surface of the pipe 2. Without being limited by the material of the pipe 2, the pipe thermometer 1 can be securely attached. In addition, the pipe thermometer 1 can be easily attached to and detached from the pipe 2. When the pipe thermometer 1 is attached to the pipe 2, it is not necessary to fix the thermometer body 3 separately, and the workability is good. Furthermore, since it is operated by the solar cell section 13, no power supply wiring or the like is required, and the extra length of wiring 8 can be stored in the wiring storage section 35, so that the entire pipe thermometer 1 is compactly attached. be able to. It is possible to provide an excellent design that gives a simple and functional beauty without giving a complicated appearance.

That is, the numbers displayed on the display unit 12 are horizontally written in the same direction as the central axis of the inner curved surface of the covering member 5. As shown in FIG. 23, when the pipe thermometer 51 is attached to the pipe 52 arranged substantially in the horizontal direction, the numbers and symbols indicating the temperature of the display unit 12 are attached so as to be written horizontally in the substantially horizontal direction. It is done. Therefore, it is easy to read the displayed temperature.
