Fail detection of abnormal temperature change of tunnels, cables and pipelines can always cause problems such as fire and economic loss, and the current temperature detection technology is facing problems of long acquisition time and low event locating accuracy. The early warning to the abnormal temperature change is recommended for preventing furthermore damage and the continuous real-time monitoring can provide more efficient property management and maintenance.

 
Benefits   Key Features   Applications
         

AgilFence-T is a distributed temperature sensing system to record real-time temperature along the entire length of the area covered by the optic fibre cable continuously without any blind points and interference. It can monitor every point of the length of the area and locate the abnormal temperature change accurately either caused by system faults or third party intrusion. After analysing the temperature received from the optical fibre, an alarm will be triggered if the event is a threat to the property.

 
   
No blind zones along the entire length of the area covered by the optic fibre cable
Continuous interference-free monitoring
Early warning to the threat
No maintenance required
Easy deployment

 

 
   
Oil and gas pipeline leakage detection
Fire detection in the tunnel
Power cable and transmission line monitoring
In-Building Electrical in cold environment
Water pipeline monitoring System Fault

 

 

How it works

 

The AgilFence-T uses Raman-effect and Optical Time Domain Reflectometer (OTDR) technology for distributed temperature sensing along an optical fibre. When a light pulse is launched into the fibre and falls on the thermally excited molecular lattice, the light scatters called Raman Scattering will occur, being received and analysed by the interrogation unit and processing unit. The amplitude of the scattered light is directly related to the intensity of thermal excitation. If the amplitude is higher than the threshold set, the alarm will be triggered. Furthermore, because of the constant speed of light in the fibre, the travel distance of the light can be easily calculated from the time of travelling, therefore, the event can be located accurately.
