The high-precision static level with fiber Bragg grating is used to monitor the relative settlement of multiple points, that is, the change in the vertical displacement of each measurement point relative to the reference point, thereby accurately calculating the relative settlement of each measurement point.
Application field
This sensor is mainly used for high-precision real-time monitoring of settlement in railways, subways, roadbeds, tunnels, DAMS and various structures. It can also be used for monitoring the deflection of Bridges and vertical deformation of other structures.
Product features
Good seismic resistance, lightweight float, and less affected by earthquakes; Intrinsically safe, it is not affected by electromagnetic interference, and has strong resistance to corrosion, pollution and lightning strikes.
