YZ2400 Disk(full Range)underground Electronic Marker


YZ2400 Underground Electronic Marker has two models (ID or No ID). It consists of a sealed shell containing a passive antenna - a low-frequency resonance circuit tuned to a certain frequency. The ID version integrates an ID chip.
Depending on the resonant frequency and the color, the YZ2400 are used to mark a wide range of underground facilities, such as telecommunication lines, power supply networks, cable television networks, water supply pipelines, wastewater networks, oil and gas pipelines, and so on.


YZ2400 can be installed at a certain interval, or at the turning of changing trend and at some event points, such as connection points, valves, well covers, T-shaped branches, etc. According to the project importance and project budget, the installing density can vary from several meters to tens of meters, usually 10-20 meters.
