EVAII End-Winding Vibration Sensor Kit for Hydrogen-Cooled Machine
Brand: IRIS PowerEnd-winding accelerometers for hydrogen- cooled generators based on fibre optic technology that can be used with the Iris Power EVTracII, the GuardII monitoring systems.
Features- Single or dual axis sensing directions
- Single optical fiber for each sensing axis
- Flexible optical cables
- Dual axis sensor has low cross sensitivity increasing accuracy
- Safe in high voltage and high magnetic fields
- EVAII maximum continuous operation to 200°C
- Low sensitivity to cable vibration
- Accelerometer reliability extensively evaluated using accelerated life testing at high temperature and high vibration levels
- Electro-Optical Drivers (EOD) are not part of the feedthrough and are not mounted on the generator frame, ensuring a longer life and easier maintenance
- Optical Fiber from sensor to Electro- Optical Driver ensuring no RF interference
- Electro-Optical Driver test point enables calibration with fine adjust buttons
- Any EVAII sensor can be paired with any EOD
- Calibrated using Back-to-Back comparison per ISO 16063-21
- Standard 100 mV/g electrical output compatible with any standard vibration monitoring instrument
- Multichannel feedthrough consists of 8 or 14 fiber connectors on each side of the penetration
- Embedded in a cured resin providing a unique self reinforcing seal
- Frame hole diameter required is 25.4 mm (1”)
- Hydrostatic pressure tested to 400 psi (2800 kPa)
