FBG Displacement Sensor
The model FBG-DST displacement sensor 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. It is mainly used for long-term monitoring of displacement, cracks or joints for railways, highways,bridges and civil buildings, tunnels, hydropower and hydraulic engineering.
Overview
FBG-DST type fiber Bragg grating displacement sensor can be used for long-term deployment on the surface of concrete, steel structures and other structures to measure the opening and closing of cracks or expansion joints in concrete, rocks and structures. It is also suitable for displacement measurement of various structures. Mainly used for long-term monitoring and automated periodic measurement of railways, highways, bridges, civil buildings, tunnels, hydropower and water conservancy project monitoring. The sensor is installed with a pull rod/rope, and a temperature fiber grating is installed inside the sensor to enable automatic temperature compensation.
Characteristic:
- Built-in temperature compensation;
- Anti-electromagnetic interference;
- Long term zero stability;
- Easy to build a distributed sensor network;
Application scenarios:
- Bridge health monitoring;
- Building health monitoring;
- Steel structure health monitoring;
- Oil pipeline health monitoring;
