Weldable FBG Strain Gauge Sensor

Model#:FM-FBG-W
MFG PART#:

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.
