Embedded FBG Strain Gauge Sensor
Embedded FBG Strain Gauge Sensor with Temperature Compensation
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.
