Temperature and Humidity Type Weak-Reflection Fiber Bragg Grating Sensing Cable

The temperature and humidity type weak-reflection fiber Bragg grating (FBG) sensing cable is a special fiber-optic sensing product integrating simultaneous temperature and humidity monitoring. The product adopts weak-reflection FBG array technology, combined with humidity-sensitive coating and sensitization packaging processes, to achieve quasi-distributed, passive, long-distance temperature and humidity monitoring. The cable uses a stainless steel armored tube, aramid, and stainless steel wire reinforcement structure, providing good tensile and compressive performance and environmental adaptability. It can be widely used for long-term temperature and humidity monitoring in infrastructure, underground engineering, and industrial environments.
