The MARKER 2500 is an electrically passive marker and serves for marking of significant points in underground systems. The markers are buried over the line during the laying of the line or during a repair (e.g. cable joint) and can be reliably pinpoint located even aftermany years.
This mode of marking is mainly applied for nonmetallic lines, e.g. fiber optic cables or plastic gas or water pipes which cannot be traced with conventional methods. Even over cable sections, the burying of markers (e.g. for marking of joints, coil boxes or conduits) has proved successful. |
