Evaii Fiber Optic Accelerometers

Non-metallic fiber optic accelerometers for measuring and analyzing stator winding head vibrations for generators.

The sensors are capable of measuring radial and tangential vibration in high voltage and high magnetic fields as in air-cooled or hydrogen-cooled generators.

  • Single or dual axis sensing directions
  • Single optical fiber for each sensor axis
  • Flexible optical cables
  • Dual-axis sensor with low cross-sensitivity for increased accuracy
  • Safe in high voltage and high magnetic fields
  • Maximum continuous operation of EVAII at 200C
  • Low sensitivity to cable vibrations
  • Accelerometer reliability extensively evaluated by accelerated life testing at high temperatures and high vibration levels.
  • Electro-optical controllers are not mounted on the engine or generator frame, ensuring longer life and easier maintenance
  • Optical fiber from sensor to electro-optical conductor to ensure no RF interference
  • Electro-optical conductor test point allows calibration with fine tuning knobs
  • Any EVAII sensor can be combined with any EOD
  • Calibration by side-by-side comparison according to ISO 16063-21
  • Standard 100 mV/g electrical output compatible with any standard vibration monitoring instruments
