The strain sensors make use of the sensitivity of fiber grating to measure the strain. The FBG is fixed inside a stainless steel housing between two anchoring points. The housing consists of a sliding mechanism that allows both ends to move freely relative to each other.
Features:
Excellent repeatability and reliability
Excellent waterproof performance
Try harsh environments
Applications:
The strain sensors used in civil engineering construction monitoring and long-term health monitoring, such as: bridges, interchanges, high-rise buildings, large steel construction.
