l  PRODUCT DESCRIPTION

ED2000 Underground Electronic Marker have two models(ID or Non 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 ED2000  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.

 

l  APPLICATIONS

ED2000  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 instralling density can vary from several meters to tens of meters, usually 10-20 meters.

l  Installing the Marker

· Place the marker on nonmetal cable

· Place a minimum of 4 inches (10 cm) of fill dirt over the cable with metal (including shielded cable, Coaxial cable etc.).

· Sand should be used to cover the marker before covering soil. It can give better protection to marker
