FBG sensor can be installed before wet concrete is applied, therefore
you can monitor concrete during its setting and presstresing, during
load tests etc

The sensor cable is deployed as an intrusion detection barrier
along a site perimeter
The sensor cable can also be buried covertly in
• Gravel
• Sand
• Sod
• Other factory approved media
Common barriers:
•chain link fences, ornamental fences,
•anti-climb fences, walls, rooftops, walls
•ceilings.
The APU can be located up to 20 Km from sensor cable
19
 Unique fibre optic system for noise detection along the fibre.
 Consist from two elements – optical fibre and the reading unit.
 An acoustic signal is recorded for each metre along the fibre.
 The system can detect the position of an event
 Can distinguish separate events more than two metres apart.
