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
20
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.
21
maximum fibre length 50 km maximum spatial resolution ( 15 km ) 1 m maximum spatial resolution ( 50 km ) 5 m minimum separation of two events +/-2 m maximum signal bandwidth 10 kHz
detection distance from footsteps 15 mdetection distance from vehicle 40 m
APPLICATION cable theft rock falls instrusion detection system other security applications speed, direction and position of trains
22
Completely passive sensor, no electrical parts Absolute EMI/RFI immunity Exceptionally low noise density Frequency up to 330 Hz Standard analog output Small, lightweight design High reliability and environmental stability Plug-and-play system
Single or dual axis fiber optic accelerometers for remote monitoring of vibration in one or two orthogonal directions
APPLICATIONS End-winding vibration monitoring HV and power application RF areas Nuclear facilities
