FBG Strain Gauges (Surface Type)

FBG Strain Gauges (Surface Type)

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.

FBG Liquid Level Sensor

FBG Liquid Level Sensor

The MAS- FBG-HLS static level is composed of a series of high-precision FBG liquid level sensors and liquid storage tanks, and the liquid storage tanks are connected by connecting pipes. The reference tank is placed at a stable horizontal base point, and other liquid storage tanks are placed at different positions with approximately the same elevation. When other liquid storage tanks rise and fall relative to the reference tank, it will cause the liquid level in the tank to rise or fall. By measuring the change of the liquid level and understanding the lifting and deformation of the measured point relative to the horizontal base point, the settlement of 0.05mm can be monitored. Mainly applicable to dams, bridges, tunnels, subways, railways, roadbeds, cutting, and bridge transition sections, such as the need to monitor deflection, settlement and vertical deformation of the occasion.
