After years of engineering and field needs, KJIT has developed an industrial wireless network system based on LORA, NB-IoT and other communications, building an information bridge between the field and the control room, allowing you to communicate in vast areas and Comprehensive monitoring of areas inaccessible to personnel。

○ KJT-WN series wireless proximity switches bring you more convenience

● There is no need to dig trenches and wire cables, which greatly reduces cable and labor costs and the project cycle.

● Simplify engineering design and reduce the workload of designers (especially cable routing).

● Affected by natural terrain such as bridges, rivers, and mountains, cables cannot be laid arbitrarily.

● According to the increase of detection points, a private data collection network can be quickly established, and the expansion is flexible and convenient.

● When a fault occurs, the detection points are concentrated, eliminating the cumbersome tasks encountered in the past when inspecting along the line.
