Technical Field

[0001] This utility model relates to the field of temperature detection equipment, specifically a temperature transmitter. Background Technology

[0002] A temperature transmitter is a sensor that converts temperature signals into a standard signal output, with the temperature probe and explosion-proof housing integrated into a single structure. Existing temperature transmitters are typically used in industrial applications; however, different usage scenarios necessitate custom design of the entire transmitter for each application, such as probe length and the fixed diameter for mounting to external equipment. Consequently, the reusability of existing temperature transmitters is low, increasing industrial production costs. Utility Model Content

[0003] In view of this, the present invention provides a temperature transmitter to solve the problems of low reusability and increased production costs caused by the need for complete redesign of existing temperature transmitters for different application scenarios.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The probe has a hollow structure, with one end fixed to the first end of the mounting base, which is used to fix it to an external device.

[0007] The support rod has a hollow structure. The first end of the support rod is fixed to the second end of the mounting base, and the second end is fixed to the explosion-proof box.

[0008] The transmitter module is housed in an explosion-proof box;

[0009] The cable is installed inside the support rod. One end of the cable extends from one end of the support rod, passes through the mounting base, and connects to the temperature measuring element installed inside the probe. The other end extends from the other end of the support rod and connects to the transmitter module.

[0010] Preferably, the mounting base has external threads on its exterior.

[0011] Preferably, the second end of the mounting base has an internal thread;

[0012] The first end of the support rod has an external thread that mates with the internal thread.

[0013] Preferably, the second end of the mounting base is welded to the first end of the support rod.

[0014] Preferably, the second end of the support rod is threadedly connected to the explosion-proof box.

[0015] Preferably, it also includes: a lock nut;

[0016] The locking nut is located inside the explosion-proof box and is threaded to the second end of the support rod. The locking nut is used to prevent the support rod from coming out of the explosion-proof box.

[0039] It should also be noted that different devices use different thread types. Therefore, the mounting base 6 of this application can also be configured with corresponding external threads according to the thread type of different devices.

[0040] Furthermore, the second end of the mounting base 6 is provided with an internal thread;

[0041] The first end of the support rod 5 has an external thread that mates with the internal thread.

[0042] It should be noted that by providing an internal thread at the second end of the mounting base 6 and an external thread that mates with the internal thread at the first end of the support rod 5, the second end of the mounting base 6 can be threadedly connected to the support rod 5, effectively ensuring the connection strength between the mounting base 6 and the support rod 5 and preventing the mounting base 6 from separating from the support rod 5.

[0043] Specifically, the second end of the mounting base 6 is welded to the first end of the support rod 5.
