Introduction
Surface Mounted Fiber Grating Strain Sensors FBG-S-M-S-01/FBG-S-M-ST-01 can meet the strain measurement needs of various occasions, and can be mounted on different monitoring positions such as concrete surface or steel surface, mainly used to measure the strain of steel structure and concrete surface. The external strain is transmitted to the internal fiber grating through the sensor mount, and the high-precision fiber grating converts the small strain sensed into sensitive light wavelengths, which are analyzed by the fiber grating demodulator.
Features
- High accuracy, resolution and stability
- Built-in temperature compensation (FBG-S-M-ST-01)
- Anti-electromagnetic interference
- Long-term zero stability
- Easy to build distributed sensor networks
- Easy to install and reusable
Applications
- Suitable for strain monitoring of bridges, gas pipelines, etc.
- Large steel structures, such as transmission line pylons, cranes and hoists
- Surface strain monitoring of steel rails
- Surface strain measurement of steel structures and concrete
