TZY-F0T distributed fiber optic temperature measurement technology is a new technology used for real-time measurement of spatial temperature field distribution. It can continuously measure the temperature along the fiber optic cable. The TZY-FOT distributed fiber optic temperature measurement system (DTS) can measure distances of tens of kilometers and has a spatial resolution of up to 0.5m. It has the advantages of high accuracy, no charge, resistance to radio frequency and electromagnetic interference, flame resistance, explosion resistance, corrosion resistance, high voltage and strong electromagnetic field resistance, radiation resistance, fast data transmission and reading speed, and good adaptive performance. It can work in various harmful environments and is particularly suitable for applications that require large-scale multi-point measurement.

It can achieve distributed temperature measurement of the entire cable tray and cable trench, timely detect cable hotspots, and prevent them from "burning", which is of great significance for operation.

3.1 By using a single core optical fiber, detection and signal transmission can be completed, and all settings are completed at the terminal, making the system simple and reliable. Traditional temperature sensors can only monitor specific local parts of cables, and the sensors require control circuits for connection, resulting in a complex structure.

3.2 Fiber optic cables have a long lifespan of up to 30 years and a monitoring distance of up to 30 kilometers. Traditional electronic sensors have a short lifespan and require a large number of spare parts, resulting in a heavy workload for maintenance and repair.

3.3 The detection and transmission components of the fiber optic sensing system are passive optical devices, which have no radiation to the outside and are resistant to electromagnetic, radio frequency, lightning strikes, radar and other influences; Simultaneously corrosion-resistant, capable of operating in harsh environments that traditional sensors cannot adapt to.

3.4 High measurement accuracy and resolution, with a temperature measurement accuracy of ± 0.5 ℃; The spatial resolution can reach 0.5 meters, which is equivalent to one sensor every 0.5 meters, enabling real-time monitoring of fire spread through temperature curves.

3.5 It has self diagnostic function, and the optical cable has fault self diagnosis and self positioning functions.
