Weldable FBG Strain Gauge Sensor
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.
Key Features
-
Excellent repeatability and reliability
-
Excellent waterproof performance
-
Try harsh environments
Application
-
The strain sensors used in civil engineering construc-tion monitoring and long-term health monitoring, such as: bridges, interchanges, high-rise buildings, large steel construction.
