Welcome to the OFSCN® Official Technical Inquiry & Product Q&A forum.
The OFSCN® Fiber Bragg Grating (FBG) Vibration Sensor is a specialized passive optical sensor designed for monitoring mechanical vibration, structural resonance, and seismic activity in environments where traditional electronic sensors might fail due to electromagnetic interference (EMI) or high voltage.
Technical Principles & Advantages
Unlike traditional piezoelectric or MEMS accelerometers, the OFSCN® FBG vibration sensor utilizes the shift in the Bragg wavelength of an optical fiber grating to detect acceleration.
- EMI/RFI Immunity: Since the sensing signal is light, it is completely immune to electromagnetic interference, making it ideal for power plants or high-voltage transformer monitoring.
- Long-Distance Transmission: The optical signal can travel several kilometers without loss of accuracy, which is superior to analog electrical signals.
- Passive Operation: No power is required at the sensing point, increasing reliability in remote or hazardous areas.
