We propose a complete system for the localisation, marking and mapping of underground networks and installations
The 3M markers we have selected are passive aerials with no internal power supply which may discharge. The highly robust polyethylene box resists the minerals, chemicals and extreme temperatures often encountered below the surface. The electronic marking system is composed of long-life passive markers which may be placed above important installations during their construction or used to mark installations during maintenance.
Several minutes is sufficient to learn to use the system and quickly locate the buried markers.
The detector transmits a Radio Frequency signal to the marker which returns this signal to the detector and indicates its exact location on the screen and with an audible signal.
These markers are proposed in the versions EMS (passive) or RFID (passive with individual ID and internal memory capacity) which may be programmed to include customer or network operator specific data.
The 3M range we have selected is suitable for use under trench depth and width conditions varying between 60 cm and 2.40 m in depth.
