Weldable FBG Strain Gauge Sensor

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

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.
