Fiber Optic Sensor Offers Better Monitoring

Facebook Twitter LinkedIn Email Comments
NÆRUM, Denmark, Feb. 27, 2014 — A new fiber optic acceleration sensor can be used for the high-frequency measurement of small vibrations, which could lead to better condition monitoring of rotating machines such as turbines, pumps, motors and vehicles.

Developed by Brüel & Kjær (B&K) and licensed to Smart Fibres of Bracknell, England, the sensor — fiber Bragg grating (FBG) technology called SmartAccel-HF — operates on a single axis and can tolerate extreme environments.

The use of fiber optics allows signals to be transmitted over distances of several kilometers. The sensor needs no power to operate and is immune to the effects of electromagnetic interference. It can measure vibrations from DC up to 900 Hz and has a 200-g dynamic range.

“One of the key advantages of FBG technology is the ability to multiplex numerous sensors of different measure and types on a few optical fibers,” said Chris Staveley, CEO of Smart Fibres.

The sensor could also be used as part of an integrated fiber optic system that monitors subsea pumps for the oil and gas industry.
