Praetorian Fiber Optic Sensing Conveyor Health Monitoring System

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 downtime 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
  • Quarries
  • Buildings
  • 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 belt's 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.
