The distributed fiber optic temperature monitoring system utilizes both fiber sensing signals and transmission signals, and uses advanced OTDR technology and temperature-sensitive characteristics of Raman scattered light to detect changes in temperature along different positions of the fiber to achieve truly distributed measurements. Ideal for a wide range of long distance temperature measurements and fire alarms. The system uses special temperature-sensitive optical cable as the detector, which itself is not charged, and has the advantages of essential explosion-proof, lightning protection, anti-corrosion and anti-electromagnetic interference. It has been widely used in petroleum, pipeline leakage, tunnel fire detection, dam safety monitoring, power cable monitoring, etc.
