Fiber Optic Sensing Systems

HAWK’s Fiber Optic Sensing

HAWK’s Fiber Optic Sensing technology, originally developed in 2006, uses DAS as the major sensing technique and allows for real-time measurements of long assets such as pipelines, conveyors, and fences by monitoring changes that occur in a fiber optic cable affixed to the asset. This revolutionary technology has the ability to protect assets, equipment, and perimeters. HAWK’s Fiber Optic System is modular in design and can monitor up to 80km (50mi) in real-time 24/7. This type of intelligent monitoring is critical to operating efficiently and protecting valuable assets.

Principle of Operation 
The Fiber Optic Sensing System uses a combination of Rayleigh backscatter and time of flight technology to determine the presence, location, intensity and frequency of vibrations along an optical fiber in real time. The Fiber Optic Sensing System can be operated directly or connected to an existing Control System such as a SCADA. The Fiber Optic System can provide alarm notifications (red, amber, and green) depending on the condition of the components. Reporting and alarms can be sent to smart phones, tablets and computers via SMS and email alerts. The report includes the location of an alarm, the alarm classification, its longitude and latitude, the alarm intensity as well as the time and date. 

  • Proven ROI by predicting breakages and failure BEFORE occurring 
  • Immune to the effects of a broken or cut fiber 
  • System is passive, no electricity is required in the field 
  • Self-diagnostics monitor the unit’s condition and maintain optimum performance 
  • No maintenance or calibration require after commissioning 
  • Monitor up at 80km (50mi) at the same time. 
  • 24/7 real-time monitoring
  • Conveyors 
  • Pipelines (above ground or buried) 
  •  Perimeters 
  • Fences 
  • Roads 
  • Railways 
  • Tunnels 
  • Bridges
Praetorian Fiber Optic Sensing Conveyor Health Monitoring System

The Praetorian Conveyor Health Monitoring System (CHMS) is a plant & site wide single solution for detecting when critical parts of the idler are beginning to fail. The early detection warnings allow operators to control down time and avoid catastrophic costly unplanned shutdowns. HAWKÍs Praetorian Fiber Optic Sensing detects abnormalities in conveyor idler performance that other technologies cannot.

Praetorian Fiber Optic Sensing for Pipeline Monitoring and Leak Detection

The Praetorian Fiber Optic Sensing System can be installed on a buried or unburied pipeline and can immediately detect pipeline leakage, ground disturbances, manual and machine excavation, theft, hot tapping and vehicle movement. The Fiber Optic System continually monitors large spans of pipeline, looking for vibration and temperature changes. Once a detection occurs, the system alerts the operator or security personal to the exact location of disturbance in the pipeline. This type of real-time intelligent monitoring is critical to operating efficiently and protecting valuable assets.

Praetorian Fiber Optic Sensing for Perimeter Security and Threat Detection

The Praetorian Fiber Optic Sensing System can be installed along a fence or perimeter and can detect, identify and report any movements. This system has limitless applications and can be installed on anything from explosive storage areas to farms and ranches. The fast processing speed and pulse rate allow the Fiber Optic System to detect minute interferences that may otherwise go unnoticed. Some examples of detectable activates include intruder movement along a perimeter, intruders cutting or climbing a fence, vehicle movement along a perimeter and digging, excavating or trenching. The Fiber Optic Sensing system is crucial for keeping valuable assets secure and protected.
