Fiber Sensing and Fiber Optics Implement more effective testing and provide services that exceeded expectations!

Fiber Bragg Grating Sensing Monitoring System

Traditional sensors are mainly electrical sensors, and electrical signals serve as carriers of external parameter changes. Various technological and application bottlenecks have gradually emerged. Fiber optic grating sensing systems, due to their advantages of resistance to electromagnetic interference, intrinsic safety, small size, light weight, and large-scale reuse, are incomparable to electrical sensors. They are very suitable for long-term monitoring in harsh environments such as flammable and explosive, strong electricity and strong magnetism, and unmanned operation, such as temperature, strain, pressure, etc Displacement, vibration, acceleration, etc.
