Distributed Raman optical fiber temperature detector

　　The distributed optical fiber temperature detection system replaces thousands of point-type temperature sensors with a single optical fiber. It uses Raman scattering of quartz optical fiber and fiber laser lidar positioning technology. Temperature measurement does not require electricity. It is intrinsically safe and particularly suitable for large spaces. Operating temperature monitoring of many equipment such as oil and gas pipeline leakage, coal storage bins, grain silos, brewing tanks, chemical reactors, coal conveyor belts, cable joints, cable trays, power distribution cabinets, transformers, batteries, motors, etc. Send an alarm and accurately locate to a specific physical location.

Key technical indicators:

　　Detection distance: 5m～20km; space positioning accuracy: ±1m; minimum temperature sensing length: 3m; temperature accuracy: ±1℃; temperature resolution: 0.1℃; number of channels: 1 (customizable)
