  • FGB Strain Gauges

Type FBG-SG-SM surface fiber grating strain gauge can meet the needs of surface strain measurement in various occasions. It can be installed on the surface of concrete or steel structure, mainly used to measure the surface strain of concrete and steel structure. The external strain transmits the strain to the internal fiber grating through the sensor mount, and the reflection center wavelength of the grating will change, and then the fiber grating demodulator performs demodulation analysis and calculates the strain value.

Overview


The sensor can be used for short-term or long-term monitoring of structural stress changes, state analysis, and realization of structural health status diagnosis and early warning purposes. The sensor is small and easy to install. Strain gauges are connected in series or in parallel, which is easy to form a quasi-distributed sensor network. It can be widely used in stress-strain testing and long-term monitoring of structures such as bridges, buildings, hydraulic engineering, and steel structures.
