Sensor selection - Power Generation industry

Following are the top features required of a quality vibration sensor in the Power Generation (fossil fuel, nuclear, hydro) industry, along with the reasons why:
  • Velocity and/or acceleration: For absolute shaft vibration
  • High temperature, ≥ 120 °C (≥ 250 °F): For steam leaks
  • ±5% sensitivity precision: May be used for API 670 machine trip
  • High EMI/RFI shielding: High voltage environment 

Good - General purpose monitoring:

Better
- Elevated temperatures:

Best - Higher precision:
