FiberStrike FBG Accelerometer
A fiber optic accelerometer for vibration measurement that can be distributed on a multi-sensor fiber network alongside other FiberStrike sensors. Offered as a drop-in alternative to conventional electrical accelerometers.
Technical overview
The sensor is an FBG device, so it inherits EMI immunity and lightning and corrosion resistance and needs no power at the measurement point. CEL states it measures vibration with frequency ranges up to 350 Hz. It is packaged for challenging environments and is intended for monitoring wind- and traffic-induced acceleration, instantaneous loads, vibrational modes and the effects of seismic or nearby construction activity. CEL publishes no accelerometer sensitivity, g-range, axis count or noise floor figures on its site or in any downloadable datasheet.
Features
- Monitoring of wind- and traffic-induced acceleration and instantaneous loads
- Monitoring of vibrational modes, effects of seismic activity or nearby construction activities
- EMI immunity, robust packaging, and lightning/corrosion resistance
- Can be used as a replacement for conventional accelerometers
- Supports multi-sensor distributed systems with other sensors
