[0020] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0021] Example 1

[0022] This embodiment provides a networked embedded industrial liquid temperature and humidity transmitter, such as Figure 1-3 As shown, the transmitter includes a housing 1 and a processor body 2 fixedly installed in the housing 1:

[0023] The processor body 2 is integrated with two power connection terminals 21 arranged side by side, four signal input terminals 22 and two signal output terminals 23;

[0024] The housing 1 includes a base shell 11 and a surface shell 12 fixedly mounted on the base shell 11. The base shell 11 and the surface shell 12 are separated. The processor body 2 is fixedly mounted on the base shell 11. The base shell 11 is provided with a fixing slot 18 for fixing the power terminal 21, four signal input terminals 22 and two signal output terminals 23. Two symmetrically arranged fixing ears 13 are fixedly mounted on the outer wall of the surface shell 12, and both fixing ears 13 are provided with a mounting hole 14.

[0025] When in use, insert the power cord into the power terminal 21, connect the signal input terminal 22 to the integrated external sensor probe 24, and connect the signal output terminal 23 to the network communication equipment for real-time monitoring and warning. The bottom shell 11 and the surface shell 12 are split into a design that is convenient for disassembly and assembly. The entire device is installed on a plane or embedded in the device to be measured through the fixing ear 13, and fixed through the mounting hole 14. It is convenient for wiring, installation, and adjustability.

[0026] Specifically, signal input terminal 22 is electrically connected to an integrated external sensor probe 24, which comprises one or more temperature and humidity sensors. During operation, the temperature and humidity sensors are connected to signal input terminal 22 via wiring and placed inside the transformer chamber to receive the desired detection information.

[0027] More specifically, the front cover 12 is fixedly mounted with a liquid crystal display panel 3 electrically connected to the processor body 2. The liquid crystal display panel 3 is embedded within the front cover 12. When in use, the liquid crystal display panel 3 intuitively displays information processed by the processor body 2, making operation easier. The embedded liquid crystal display panel 3 is also safer and does not protrude from the front cover 12, reducing the impact of external shocks on it.

[0028] Furthermore, the housing 12 is provided with a plurality of mounting cavities 16, in which a control button 25 electrically connected to the processor body 2 is slidably mounted. When in use, the function can be adjusted by the control button 25, which is convenient and quick.

[0029] Furthermore, two symmetrically arranged clamping blocks 15 are fixedly mounted on the bottom shell 11, and the ends of the clamping blocks 15 away from the bottom shell 11 are clamped to the outer wall of the top shell 12. During use, after the bottom shell 11 and the top shell 12 are fixed by bolts, the clamping blocks 15 will be clamped to the top shell 12, thereby making the connection between the bottom shell 11 and the top shell 12 tighter and more stable.

[0030] Among them, a plurality of evenly distributed heat dissipation holes 17 are opened at the edge of the outer wall of the bottom shell 11. When in use, the heat generated by the processor body 2 during operation can be discharged through the heat dissipation holes 17, reducing the operating load of the device and increasing the service life of the device.

[0031] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
