Displacement sensors

Fiber grating displacement sensors are used to measure concrete cracks, structural joints, deformation displacements, etc. The sensors are usually installed on the surface of the structure to measure the distance between the two anchor points. It can be used in conjunction with other structures and sensors to determine soil displacement. It can be used to monitor expansion displacement and compression displacement. Optical fiber displacement sensor is widely used in gap measurement of bridges, buildings, roads, dams and other buildings. Compared with traditional sensors, fiber optic Bragg displacement sensors are more durable an they can provide long-term safety.

Product features:

• Excellent performance and anti-mechanical fatigue in harsh environment;

• Intrinsically safe, not subject to electromagnetic interference, anti-corrosion, anti-pollution, anti-lightning ability;

• The internal optical fiber strain element adopts metallized package, long-term zero is stable, temperature drift is small, welding operation is simple, dynamic characteristic is good;

• The arrangement is simple and can be mixed with other FBG sensors.
