MFG PART#:
Embedded 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 performanceTry harsh environmentsApplication
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.Specification
