Distributed optical fiber temperature measurement system features
Principle of distributed optical fiber temperature measurement system
Continuous distributed temperature measurement, no measurement dead zone
Optical signal transmission, fully electrical insulation, intrinsically safe, anti-electromagnetic interference
Optical fiber is the sensor, easy to install and lay
Long measuring distance, accurate positioning of abnormal temperature points
Long fiber life, maintenance-free for decades
Fast measurement speed, high precision and low false alarm rate
The distributed optical fiber temperature sensing system consists of optical fiber temperature measuring host, temperature sensing fiber, system management software and related accessories. It uses Raman scattering and OTDR technology to realize temperature monitoring and positioning. Distributed optical fiber temperature sensing products use OTDR technology for temperature monitoring and positioning. It is a real-time, online, continuous temperature measurement system. The system can accurately detect the temperature of the temperature measurement point, and has the advantages of real-time online, high temperature measurement accuracy, intrinsic safety and immunity to electromagnetic interference. It can be widely used in electric power, petrochemical, transportation, metallurgical and other industrial places, in the production process. Real-time online monitoring of temperature conditions eliminates faults and accidents in the bud, and truly prevents them from happening.
