Introduction
Fiber Optic Grating Earth Pressure Sensor FBG-S-L-C-01 is a new type of fiber optic earth pressure gauge developed by adopting high quality constant elasticity alloy as the pressure transmitter and utilizing the inherent strain sensing characteristics of fiber optic grating.FBG-S-L-C-01 is suitable for the measurement of earth stresses in earth and rock dams, jetties, revetments, quay walls, high-rise buildings, pipeline foundations, bridge abutments, retaining walls, tunnels, subways, airports and other construction foundations, and impermeable wall structures as well as freezing forces in glacial permafrost, Highways, railroads and other building foundations, and impermeable wall structures, as well as glacial permafrost freezing force measurement. FBG-S-L-C-01 has the advantages of good stability, suitable for long-term monitoring, and comes with temperature compensation.
Features
- Anti-electromagnetic interference, intrinsically explosion-proof, lightning strike resistant
- Excellent temperature resistance, corrosion resistance, aging resistance
- Built-in automatic temperature compensation
- High precision and high resolution
- Integrated package, more stable performance
- Easy to use, quick installation, reusable
Applications
- Highway Health Monitoring
