Praetorian Fiber Optic Sensing Conveyor Health Monitoring System
Actualizado: 2024-01-02
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.
Praetorian Fiber Optic Sensing for Pipeline Monitoring and Leak Detection
Actualizado: 2024-01-02
The Praetorian emits a laser pulse down a fiber optic cable to measure vibration and temperature as well as the position of that vibration and temperature. Using a combination of Rayleigh backscatter, Brillouin Backscatter*, and time of flight, Praetorian determines the presence, location, intensity, and frequency of vibrations and temperature changes along an optical fiber in real-time. Rayleigh Backscatter responds to physical vibration imparted on the fiber by disturbances to the application. HAWK\'s signal analysis software allows Praetorian to quickly determine the most likely origin of the vibration and report any erroneous signals to maintenance personnel of potential issues with the pipeline. Brillouin Backscatter* responds to shifts in environmental temperatures and is used to detect the temperature drop associated with the reduction in fluid pressure caused by the leak taking advantage of the Joule-Thomson effect.
Praetorian Fiber Optic Sensing for Power Cable Monitoring

Using a combination of Rayleigh backscatter, Brillouin backscatter and time of flight, Praetorian determines the presence, location, intensity and frequency of vibrations and temperature changes along an optical fiber in real time. These fibers can be integral to or laid with high voltage power transmission cables and operate as a comprehensive Power Cable Monitoring System (PCMS).
