Fiber Optic Sensing Conveyor Monitoring System

HAWK's Praetorian Conveyor Health Monitoring System (CHMS) is a site-wide single solution that detects 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. The Praetorian Fiber Optic Sensing conveyor monitor system detects abnormalities in conveyor idler performance that other technologies cannot.

Principle of Operation

The Praetorian system Interrogator unit is connected to one end of a fiber optic cable attached to the conveyor belt 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 (backscattered) to the light source, where the interrogator records and analyses it, looking for changes to its physical effects in the application.
