The EC1000 series fiber optic grating monitoring device provides input light source for the fiber optic grating sensor array, and analyzes the optical signal output by the fiber optic grating sensor to calculate the temperature values of all measurement points. The device adopts a standard 19 inch 2U chassis design, with a powerful embedded computer built-in. It is equipped with standard RS232 and 10M Ethernet communication interfaces, with high reliability and strong environmental adaptability. The EC1000 series fiber Bragg grating monitoring device meets the high requirements for dynamic performance in both laboratory and practical engineering applications. It is a high-precision, high-resolution, and multifunctional device. It can be widely used for long-term health monitoring of large structures such as bridges, dams, tunnels, oil tanks, cables, switchgear, and long-distance oil pipelines. It can also be used for spectral analysis and optical device testing related to wavelength and power.
