  By the way, in a sensor and a communication device as described above, the sensor and the communication device may be connected by a wave-shaped flexible tube, and a signal line from the sensor may be passed through the flexible tube and connected to the communication device. By doing so, the position and orientation of the communication device can be arbitrarily adjusted. However, in this case, there is a possibility that the end of the flexible tube, that is, the connection portion between the sensor and the communication device in the flexible tube may be damaged. In other words, since the strength of the flexible tube is relatively low, there is a possibility that the flexible tube may be damaged due to the vibration of the measurement object to which the sensor is fixed.

  The technology disclosed in the present application has been made in view of such circumstances, and the purpose thereof is to connect the sensor device in which the sensor body and the communication device are connected while the position and orientation of the communication device can be adjusted. It is in building the connection structure of the communication apparatus and sensor main body which can suppress damage to a part.

  The sensor device of the present application includes a sensor body, a communication device, and a connection member. The sensor body is fixed to a measurement object and detects at least one of temperature and vibration of the measurement object. The communication device transmits a detection signal of the sensor body to an external device. The connection member connects the sensor body and the communication device, and includes two bent pipes and a union joint that connects the two bent pipes.

  According to the sensor device of the present application, the connection member that connects the sensor main body and the communication device has two bent pipes and a union joint that connects the two bent pipes. That is, the connecting member has two bending pipes connected to each other by a union joint. Therefore, at least one of the two bending pipes can be rotated around the axis of the union joint and can be connected in an arbitrary direction. Thereby, even if it does not use a flexible tube as a connection member like before, the position and direction of a communication apparatus can be adjusted arbitrarily. Therefore, it is possible to construct a connection configuration of the communication device and the sensor main body that can suppress damage to the connection portion while allowing the position and orientation of the communication device to be adjusted.

FIG. 1 is a front view illustrating a schematic configuration of the sensor device according to the embodiment. FIG. 2 is a front view illustrating a schematic configuration of the sensor device according to the embodiment.

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

  As shown in FIG. 1, the sensor device 1 of the present embodiment includes a sensor main body 2, a communication device 3, and a connection member 4.

  In the sensor device 1, the sensor main body 2 is connected to a fixture (not shown) and fixed to a measurement object (for example, a steam trap). The sensor body 2 is a so-called fixed type sensor that detects two vibrations and temperature of the measurement object. The communication device 3 is a wireless communication device having an antenna 3a. Although not shown, the communication device 3 includes a signal processing circuit and a transmitter. The connection member 4 connects the sensor body 2 and the communication device 3. For example, the sensor device 1 is fixed to the measurement object in a state of extending in a generally vertical direction.

  As shown in FIG. 1, the connection member 4 according to the present embodiment includes three pipes 41, 42, 43 and four union joints 44, 45, 46, 47.

  The three tubes 41, 42, and 43 are all bent tubes. Specifically, the 1st pipe | tube 41 is a bending part which has a linear part and the both ends 41a and 41b bent. Both ends 41a and 41b of the first tube 41 are bent at 45 ° in the same direction (side). The second tube 42 and the third tube 43 are both elbow tubes bent by 45 °. The second pipe 42 has one end (upper end) connected to the communication device 3 by a first union joint 44 and the other end (lower end) connected to one end (upper end) of the first pipe 41 by a second union joint 45. . One end (upper end) of the third pipe 43 is connected to the other end (lower end) of the first pipe 41 by a third union joint 46, and the other end (lower end) is connected to the sensor body 2 by a fourth union joint 47. Yes.

  As described above, the connecting member 4 of the present embodiment includes the two bent pipes (the first pipe 41 and the second pipe 42) connected to each other by the second union joint 45 and the third union joint 46. It has two connected bending pipes (first pipe 41 and third pipe 43).

  In the connection member 4 configured as described above, each of the three pipes 41, 42, 43 can be connected in any direction by the union joints 44, 45, 46, 47. Specifically, the second pipe 42 is connected in an arbitrary direction by rotating (turning) around the central axis X1 of the first union joint 44 or the central axis X2 of the second union joint 45. The first pipe 41 is connected in an arbitrary direction by rotating (turning) around the central axis X2 of the second union joint 45 or the central axis X3 of the third union joint 46. The third pipe 43 is connected in an arbitrary direction by rotating (turning) around the central axis X3 of the third union joint 46 or the central axis X4 of the fourth union joint 47.

  Thus, by connecting each of the three pipes 41, 42, 43 in an arbitrary direction, the connecting member 4 can be configured as shown in FIG. 2, for example. Thereby, it is possible to connect the sensor main body 2 and the communication device 3 while preventing interference with other devices and the pipe 5, and to adjust the position and orientation of the communication device 3. Further, in the connection member 4 of the present embodiment, the orientation of the communication device 3 itself can be adjusted by rotating (turning) the communication device 3 around the central axis X1 of the first union joint 44.

Can be connected in any orientation. Accordingly, the position and orientation of the communication device 3 can be arbitrarily adjusted without using a flexible pipe as a connection member as in the conventional case. Therefore, it is possible to construct a connection configuration of the sensor main body 2 and the communication device 3 that can suppress the damage of the connection member 4 while allowing the position and orientation of the communication device 3 to be adjusted.

  In the sensor device 1 of the above embodiment, since the communication device 3 is connected to the first pipe 41 by the first union joint 44, the communication device 3 itself is also rotated (turned) in an arbitrary direction and connected. be able to.
