[0048] The other end of the cable 8 passes through the upper mounting base 3 and is connected to the transmitter module 2. The upper mounting base 3 is used to fix the cable 8.
[0049] It should be noted that transmitter module 2 is a circuit module that processes and converts the temperature signal measured by temperature sensing element 5. The output mode and various electrical parameters can be adjusted according to customer needs.
[0050] In this embodiment of the utility model, the probe 4 is configured as a hollow structure, and one end of the probe 4 is fixed to the first end of the lower mounting base 7 and fixed to the external equipment through the lower mounting base 7. The cable fixing member 6 for fixing the cable 8 is set at the second end of the lower mounting base 7. The temperature measuring element 5 is set inside the probe 4.

The other end of the cable 8 passes through the upper mounting base 3 and is connected to the transmitter module 2, and the cable 8 is fixed through the upper mounting base 3. With the aforementioned split-type temperature transmitter, since the explosion-proof box 1 and probe 4 are set separately, when facing different usage scenarios, it is only necessary to set the mounting diameter of the lower mounting base 7, the length and diameter of the probe 4 according to the requirements, and then assemble the temperature sensing element 5 inside the probe 4 to obtain the required split-type temperature transmitter. Compared with the existing integrated temperature transmitter, this application can achieve reuse by replacing the corresponding lower mounting base 7 and probe 4 as needed. Therefore, the split-type temperature transmitter of this application can effectively reduce industrial production costs.
[0051] Specifically, the lower mounting base 7 has external threads on its exterior.
[0052] It should be noted that by opening external threads on the outside of the lower mounting base 7, the lower mounting base 7 can be threadedly fixedly connected to the external device through the external threads.
[0053] It should also be noted that different devices use different thread systems. Therefore, the lower mounting base 7 of this application can also be configured with corresponding external threads according to the thread system of different devices.
[0054] Furthermore, the cable fixing component 6 is a top cover, wherein the top cover has a through hole for the cable 8 to pass through;
[0055] One end of the upper cover is engaged with the second end of the lower mounting base 7;
[0056] The other end of the top cover is provided with a first cylindrical body 6161, which is connected to the through hole. The first cylindrical body 6161 is deformed to clamp the cable 8.
[0057] It should be noted that the first cylinder 6161 is a component made of metal material, and the first cylinder 6161 can be deformed by clamping it with pliers to clamp and fix the cable 8. However, the first cylinder 6161 is not limited to being made of metal material.
[0058] Specifically, the upper cover is welded to the second end of the lower mounting base 7.
[0059] It should be noted that welding the upper cover to the second end of the lower mounting base 7 can further increase the connection strength between the upper cover and the lower mounting base 7, and further prevent the cable 8 from coming off.
[0060] Specifically, the first end of the upper mounting base 3 is threadedly connected to the explosion-proof box 1;
[0061] The second end of the upper mounting base 3 is used to clamp and fix the cable 8.
[0062] It should be noted that connecting the first end of the upper mounting base 3 to the explosion-proof box 1 by thread can effectively ensure the connection strength between the upper mounting base 3 and the explosion-proof box 1, while clamping and fixing the cable 8 by the second end of the upper mounting base 3 can effectively prevent the cable 8 from coming out of the explosion-proof box 1.
[0063] Specifically, the second end of the upper mounting base 3 is provided with a second cylinder 31, which is deformed to clamp the cable 8.
[0064] It should be noted that the second cylinder 31 is a component made of metal material, and the second cylinder 31 can be deformed by clamping it with pliers to clamp and fix the cable 8. However, the second cylinder 31 is not limited to being made of metal material.
[0065] Furthermore, the split-type temperature transmitter also includes: a locking nut 10;
[0066] The locking nut 10 is installed inside the explosion-proof box 1. The locking nut 10 cooperates with the first end of the upper mounting base 3. The locking nut 10 is used to prevent the upper mounting base 3 from being dislodged from the explosion-proof box 1.
[0067] It should be noted that by setting a locking nut 10 inside the explosion-proof box 1 and by having the locking nut 10 cooperate with the first end of the upper mounting base 3, the upper mounting base 3 is restricted from coming out of the explosion-proof box 1, thereby further improving the connection strength between the upper mounting base 3 and the explosion-proof box 1 and preventing the upper mounting base 3 and the cable 8 from coming out of the explosion-proof box 1.
[0068] Furthermore, the split-type temperature transmitter also includes a sheath disposed on the outer surface of the cable 8.
[0069] It should be noted that by installing a sheath on the outer surface of cable 8, the cable 8's protective capability in complex environments can be improved.
[0070] Preferably, the sheath is a metal corrugated pipe.
[0071] It should be noted that the sheath can be made of metal corrugated pipe or other flexible materials with corrosion resistance and wear resistance. Those skilled in the art can choose according to their needs.
[0072] Specifically, the transmitter is fixed to the explosion-proof box 1 by bolts.
[0073] It should be noted that the transmitter can be fixed to the explosion-proof box 1 by bolts, or by adhesive, snap-fit, or other means. Those skilled in the art can choose according to their needs.

[0076] The sealing ring 9 is fitted onto the upper mounting base 3 and is located between the annular boss and the explosion-proof box 1.
[0077] It should be noted that by providing an annular boss on the outer surface of the upper mounting base 3 and fitting the sealing ring 9 onto the upper mounting base 3, and placing it between the annular boss and the explosion-proof box 1, external water stains, dust, etc., can be prevented from entering the explosion-proof box 1, ensuring that the explosion-proof box 1 is clean, effectively extending the service life of the transmitter module 2, and thus effectively extending the service life of the split-type temperature transmitter.
