Problems to be solved by the invention
The device described in patent document 1 is used for control or monitoring, for example. Therefore, the spot inspection of the temperature sensor must be performed periodically or as needed.
In the conventional spot inspection, first, the temperature sensor is taken out from the apparatus. Then, the temperature in, for example, the room is measured by the taken-out temperature sensor. In addition, a calibrated temperature measuring instrument for spot inspection is prepared in advance. The indoor temperature measured by the temperature sensor taken out of the device is compared with the indoor temperature measured by the spot detection temperature measuring instrument.
Conventionally, the spot inspection of the temperature sensor has not been possible without taking out the temperature sensor from the apparatus. Therefore, there is a problem that the temperature of the fluid cannot be measured by the temperature sensor while the spot inspection of the temperature sensor is performed.

Fig. 1 is a diagram showing an example of a monitoring system including a temperature measuring device 1 according to embodiment 1. The monitoring system includes, for example, a temperature measuring device 1, a control device 2, and a central monitoring board 3. The temperature measuring device 1 and the control device 2 are connected by an electric wire 4. The control device 2 is connected to the central monitoring board 3 via an electric line 5.
The temperature measuring device 1 is a device for measuring the temperature of a fluid flowing through the pipe 6. The fluid may be a gas or a liquid. The temperature measuring device 1 is provided in the pipe 6. The pipe 6 is covered with a heat insulating material 7. A part of the temperature measuring device 1 is covered with a heat insulating material 7. The temperature measuring device 1 and the control device 2 are installed in a machine room of a building, for example. The central monitoring board 3 is installed in a monitoring room of a building, for example.
Fig. 2 is a diagram showing an example of the temperature measuring device 1. The temperature measuring device 1 includes, for example, a main body 11, a protection pipe 12, a cover 13, and a sensor unit 14. The profile of the temperature measuring device 1 is formed by the body 11, the protective tube 12 and the cover 13. The body 11 and the cover 13 are disposed outside the pipe 6. The portion of the protection pipe 12 forming the outline of the temperature measurement device 1 is disposed inside the pipe 6. Further, the main body 11 is covered with the heat insulating material 7. The sensor unit 14 is disposed in a space surrounded by the body 11, the protective tube 12, and the cover 13.
The protection tube 12 is a hollow member having one end closed and the other end opened. The protection tube 12 is connected to the body 11. The inner space of the main body 11 communicates with the inner space of the protective tube 12 via an opening at the other end of the protective tube 12. The cover 13 is provided to the main body 11. The cover 13 is detachable from the main body 11. Fig. 3 is a view of the temperature measuring device 1 viewed from a direction a in fig. 2.

The cover 13 is attached to the body 11 so as to close the opening 11 a.
Fig. 4 is a diagram showing an example of the sensor assembly 14. Fig. 5 is a view showing a B-B section of fig. 3. In fig. 5, only the protective tube 12 and the sensor assembly 14 are shown. Fig. 6 is a view showing a section C-C of fig. 5. Fig. 7 is a view showing a D-D section of fig. 5. The sensor unit 14 includes, for example, a terminal block 21, terminal blocks 22 to 24, a temperature sensor 25, and electric wires 26 to 28.
The terminal plate 21 has a surface 21a and a surface 21 b. The surface 21b is a face facing a direction opposite to the direction faced by the surface 21 a. In the example shown in the present embodiment, the terminal plate 21 is a disk-shaped member made of a phenol resin. The terminal plate 21 is provided to the main body 11 by, for example, a bolt 29. The terminal plate 21 is disposed in the inner space of the main body 11 so that the surface 21a can be seen when the cover 13 is detached from the main body 11. The terminal plate 21 is disposed such that the surface 21b faces the opening at the other end of the protection tube 12. Further, if the opening at the other end of the protective tube 12 is not closed as viewed in the axial direction of the protective tube 12, a member or the like for fixing the protective tube 12 to the body 11 may be disposed between the protective tube 12 and the terminal plate 21.
The terminal block 22, the terminal block 23, and the terminal block 24 are provided on the surface 21a of the terminal plate 21. The terminal block 22, the terminal block 23, and the terminal block 24 protrude from the surface 21 a. For example, the terminal block 23 is disposed in the center of the front surface 21 a. The terminal block 23 is disposed between the terminal block 22 and the terminal block 24. The terminal block 22, the terminal block 23, and the terminal block 24 are made of metal as a whole, for example. In the present embodiment, an example is shown in which the sensor unit 14 includes a terminal block fixed by a bolt. The sensor unit 14 may include a socket-type terminal block. The number of terminal blocks provided in the sensor unit 14 is not limited to the example shown in fig. 3 and the like.
The temperature sensor 25 is disposed in the inner space of the protective tube 12. The temperature sensor 25 is, for example, a sheath temperature measuring resistor. The temperature sensor 25 is disposed at the front end portion of the protective tube 12.
The electric wires 26, 27 and 28 are pulled out from the temperature sensor 25. The electric wire 26 passes through the inner space of the protection tube 12 and penetrates through the through hole 21c formed in the terminal plate 21. The electric wire 26 is connected to the terminal block 22. The temperature sensor 25 and the terminal block 22 are connected by an electric wire 26. The electric wire 27 passes through the inner space of the protection tube 12 and penetrates the through hole 21d formed in the terminal plate 21. The electric wire 27 is connected to the terminal block 23. The temperature sensor 25 and the terminal block 23 are connected by an electric wire 27. The electric wire 28 passes through the inner space of the protection tube 12 and penetrates through the through hole 21e formed in the terminal plate 21. The electric wire 28 is connected to the terminal block 24. The temperature sensor 25 and the terminal block 24 are connected by an electric wire 28.
The electric wire 4 is connected to the terminal block 22, the terminal block 23, and the terminal block 24. The electric wire 4 is disposed along the surface 21a of the terminal plate 21 and is drawn out of the main body 11.
Fig. 8 is a diagram showing an example of the temperature measuring instrument 40 for spot inspection used for spot inspection of the temperature sensor 25. The spot inspection hole 30 is a hole for inserting the corrected spot inspection temperature measuring instrument 40 into the internal space of the protection tube 12 from the surface 21a side of the terminal plate 21. The spot inspection hole 30 is formed at least in the terminal plate 21 in accordance with the position of the protection tube 12, the positions of the electric wires 26 to 28, and the like. In the present embodiment, the spot check holes 30 are formed in a straight line on the terminal block 23 and the terminal plate 21.
The temperature measuring instrument 40 for spot inspection includes, for example, a temperature sensor 41, an electric wire 42, and a mark 43. The temperature sensor 41 is, for example, a sheath temperature measuring resistor. The electric wire 42 is drawn out from the temperature sensor 41 and is arranged linearly with respect to the temperature sensor 41. The mark 43 is a mark for arranging the temperature sensor 41 at an appropriate position inside the protective tube 12. The mark 43 is provided on the electric wire 42.
In the example shown in the present embodiment, the spot check hole 30 is formed to overlap the opening at the other end of the protective tube 12 as viewed in the axial direction of the protective tube 12. In fig. 7, the position of the spot check hole 30 when viewed from the axial direction of the protective tube 12 is indicated by a one-dot chain line.
The electric wires 26 extending from the terminal block 22, the electric wires 27 extending from the terminal block 23, and the electric wires 28 extending from the terminal block 24 are arranged in the internal space of the protective tube 12 in a state where 3 electric wires are twisted, for example. The electric wires 26 to 28 pass through, for example, a central portion of the inner space of the protective tube 12. In order to prevent the temperature sensor 41 inserted from the position of the hole 30 from touching the wires 26 to 28, the hole 30 is preferably not formed at the position of the center axis of the terminal plate 21. In the example shown in the present embodiment, the central axis of the terminal plate 21 and the central axis of the protection pipe 12 are arranged on the same straight line. On the other hand, as shown in fig. 7, the center axis of the spot check hole 30 and the center axis of the protective tube 12 are not arranged on a straight line.
Next, a method of performing spot inspection on the temperature sensor 25 included in the temperature measurement device 1 will be described with reference to fig. 9 to 11. The spot check is performed to determine whether or not the temperature measured by the temperature sensor 25 indicates an accurate value. Fig. 9 is a flowchart illustrating a spot inspection method of the temperature sensor 25 in embodiment 1.
A maintenance worker of the equipment having the pipe 6 first removes the cover 13 from the main body 11 (S101). When the cover 13 is removed from the body 11, the terminal plate 21 and the terminal blocks 22 to 24 are exposed. The maintenance staff prepares the corrected temperature measuring instrument 40 for spot inspection in advance. When the maintenance worker removes the cover 13 from the main body 11, the temperature measuring device for spot inspection 40 is inserted into the spot inspection hole 30 (S102). Further, since the spot inspection hole 30 is a hole into which the temperature measuring instrument 40 for spot inspection is inserted, the diameter of the spot inspection hole 30 is slightly larger than the diameter of the temperature sensor 41 of the temperature measuring instrument 40 for spot inspection. For example, if the diameter of the temperature sensor 41 is 1.0mm, the diameter of the spot inspection hole 30 is preferably about 1.6 mm.
Fig. 10 is a cross-sectional view showing a state in which the temperature measuring instrument 40 for spot inspection is inserted into the spot inspection hole 30. The maintenance worker inserts the temperature sensor 41 of the temperature measuring instrument 40 for spot inspection into the spot inspection hole 30 from the front surface 21a side of the terminal plate 21, and arranges the temperature measuring instrument 40 for spot inspection in the inner space of the protective tube 12 (S103). Specifically, a part of the electric wire 42 and the temperature sensor 41 are disposed in the inner space of the protective tube 12. Fig. 11 is a cross-sectional view showing a state in which temperature measuring device for spot detection 40 is disposed in the internal space of protective tube 12.
In order to properly perform the spot inspection of the temperature sensor 25, it is necessary to properly arrange the temperature measuring instrument 40 for spot inspection so that the temperature sensor 41 is adjacent to the temperature sensor 25. The maintenance person, for example, inserts the spot inspection thermometer 40 into the spot inspection hole 30 until the mark 43 contacts the terminal block 23. That is, the mounting position of the mark 43 is adjusted in advance so as to be in contact with the terminal block 23 when the temperature sensor 41 is arranged at a position adjacent to the temperature sensor 25.
When the spot inspection temperature measuring instrument 40 is arranged as shown in fig. 11, the maintenance worker obtains information of the temperature T1 measured by the temperature sensor 41 (S104). For example, a controller (not shown) is connected to the electric wire 42 of the spot detection temperature measuring instrument 40. Information on the temperature T1 is shown to the controller. Further, the maintenance person obtains information of the temperature T2 measured by the temperature sensor 25 (S105). For example, information of the temperature T2 is displayed on the control device 2. The information of the temperature T2 is preferably obtained in the state shown in fig. 11, that is, when the temperature measuring instrument 40 for point detection is disposed in the internal space of the protective tube 12.
When the steps of S104 and S105 are finished, the maintenance worker compares the temperature T1 measured by the temperature sensor 41 with the temperature T2 measured by the temperature sensor 25 (S106). For example, if the difference between the temperature T1 and the temperature T2 enters the allowable range, the maintenance person determines that the temperature measurement function of the temperature sensor 25 is normal. If the difference between the temperature T1 and the temperature T2 does not fall within the allowable range, the maintenance person determines that the temperature measurement function of the temperature sensor 25 is abnormal. The allowable range is set in advance.
When the information of the temperature T1 is obtained, the maintenance worker removes the temperature measuring instrument 40 for spot inspection from the spot inspection hole 30 (S107), and attaches the cover 13 to the main body 11 (S108).
In the example shown in the present embodiment, the temperature sensor 25 is checked without detaching the sensor unit 14 from the main body 11. The spot inspection of the temperature sensor 25 is performed without detaching the wires 4 from the terminal blocks 22 to 24. Therefore, while the spot inspection of the temperature sensor 25 is performed, the information of the temperature measured by the temperature sensor 25 is also transmitted to the control device 2 and the central monitoring board 3. In the control device 2 and the central monitoring board 3, it is not necessary to stop the control or monitoring using the temperature information.
In the example shown in the present embodiment, it is not necessary to detach the temperature measuring device 1 itself from the pipe 6 when the temperature sensor 25 performs the spot inspection. Therefore, the heat insulating material 7 does not need to be torn when the spot inspection of the temperature sensor 25 is performed, and the time and labor required for the spot inspection can be reduced.
Fig. 12 and 13 are diagrams showing other examples of the temperature measuring device 1. Fig. 12 is a view corresponding to the section C-C in fig. 5. Fig. 13 is a view corresponding to the section B-B in fig. 3. In the example shown in fig. 12 and 13, the sensor unit 14 further includes a guide 31.
The guide 31 is a member for guiding the temperature measuring instrument 40 for spot testing inserted into the spot testing hole 30 to the opening at the other end of the protection tube 12. The guide 31 is provided to the terminal plate 21. The guide 31 protrudes from the surface 21b of the terminal plate 21. Fig. 12 and 13 show an example in which the guide 31 has a cylindrical shape. For example, the guide member 31 is configured such that the hollow portion is aligned with the spot inspection hole 30. In the example shown in fig. 12 and 13, the guide 31 is disposed so as to surround the edge of the spot inspection hole 30.
The electric wires 26 to 28 are twisted in the internal space of the protective tube 12, but are untwisted in the vicinity of the terminal plate 21 as shown in fig. 12 and 13. Fig. 12 shows an example of the loosening of the electric wire 28. In this case, if the sensor assembly 14 is not provided with the guide 31, a part of the electric wire 28 may be arranged on a straight line of the spot check hole 30. On the other hand, in the example shown in fig. 12 and 13, since the guide 31 is provided, the electric wire 28 is arranged so as to avoid the point inspection hole 30 as viewed in the axial direction of the protection pipe 12. The guide 31 prevents a part of the electric wire 28 from being arranged on the straight line of the click hole 30. According to the example shown in fig. 12 and 13, in S102 of fig. 9, the temperature sensor 41 of the temperature measuring instrument 40 for point detection can be easily inserted into the internal space of the protection tube 12.
