Introduction
Fiber Optic Grating Displacement Sensor FBG-S-D-ST-01 is used for long term measurements of structural beams and large buildings or other concrete, steel structures, building settlements, displacements and landslides. The sensor is mounted with a tie rod/cord for accurate and fast measurement of beam settlement, tunnel structure displacement and deformation, and building contact surfaces. Also, the sensor is internally mounted with a temperature fiber grating for automatic temperature compensation.
Features
- High precision, high reliability, high stability
- Built-in automatic temperature compensation
- All-optical measurement, intrinsically safe
- Long-term zero stability
- Easy to install
Applications
- Measurement of displacements at different depths in bridges, dams, tunnels, and various underground works.
- Measurement of ground settlement deformation and slope slippage deformation
- Long-term displacement monitoring of steel structure foundations under force deformation.
