Fiber Bragg Grating Sensor / HGG05 Fiber Bragg Grating Vertical Angle Meter
Product Categories Fiber Bragg Grating Sensors
It is mainly used for monitoring the lateral deformation of concrete dams; determining the position and deformation direction of the sliding surface of slopes and artificial slopes; monitoring the stability of foundation pit excavation, large cavern side walls, shafts, tunnels, pits and surrounding areas of underground projects; monitoring the deep displacement of landslides; monitoring the slope of docks, bridge foundations, abutments, retaining walls, etc. The product adopts CAVONO industrial-grade design, and the temperature sensitivity coefficient is reduced in the strain structure design. The fiber Bragg grating strain sensor chip with temperature compensation function is designed inside the sensor, which has accurate temperature compensation function and the measurement accuracy is not affected by the ambient temperature.
