This topic provides a technical overview of the OFSCN® Fiber Bragg Grating Vibration Sensor (also known as an FBG Vibration Detector).
Fiber Bragg Grating (FBG) vibration sensors are designed to detect mechanical oscillations and dynamic structural changes by monitoring the shift in the reflected Bragg wavelength. Unlike traditional electronic accelerometers, these sensors are passive, immune to electromagnetic interference (EMI), and suitable for long-distance signal transmission in harsh environments.
Core Technical Principles
The vibration sensor works by converting mechanical vibration into periodic strain on the FBG element. As the sensor vibrates, the grating period changes, causing a corresponding wavelength shift that can be captured at high frequencies by an FBG interrogator.
Typical Application Scenarios
- Rotating Machinery: Real-time monitoring of bearings, motors, and turbines.
- Civil Infrastructure: Vibration analysis of bridges, tunnels, and high-rise buildings.
- Power Grids: Monitoring transformer hum or cable vibrations in high-voltage environments.
- Geotechnical Engineering: Micro-seismic detection and slope stability monitoring.
