FBG Displacement Sensor

Fiber displacement sensor DST-01 is used for long-term measurement of structural beams and large buildings or other concrete, steel structures, building settlements, displacements and landslides. The sensor is installed by pulling rope, which can accurately and quickly measure the beam settlement, the displacement and deformation of the tunnel structure and the contact surface of the building. At the same time, a temperature FBG is installed inside the sensor, which can perform automatic temperature compensation.
