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. HAWK's Praetorian Fiber Optic Sensing detects abnormalities in conveyor idler performance that other technologies cannot.
- Coal mines, hazardous area suitable (no infield electronics)
- Hard rock mines
- Unmanned material handling facilities
- Processing plant conveyors
Principle of Operation
The Praetorian system Interrogator unit is connected to one end of a fiber optic cable which is attached to the conveyor belts static structure. The Interrogator produces rapidly pulsed laser light set at a precise frequency that excites the fiber and causes it to be responsive to physical changes around it. Some of this light is reflected back (backscattered) to the light source where the Interrogator records and analyses looking for changes to its physical effects in the application.
- Proven ROI by predicting breakages and failure BEFORE occuring
- Immune to the effects of a broken or cut fiber
- System is passive, no electricity is required in the field
- Self-diagnostics monitor the unitÍs 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
