Sensor selection - Oil and Gas, Refining, Petrochemicals industries

Following are the top features required of a quality vibration sensor in the Oil and Gas, Refining, and Petrochemicals industries, along with the reasons why:
  • ATEX/NEC certifications: Hazardous area
  • Minimum 10 Hz to 10 kHz frequency response: For turbines, blades and gears
  • ±5% sensitivity precision: May be used for API 670 machine trip
  • High EMI/RFI shielding: May be used for API 670 machine trip

Good - Monitoring in Class I, Division 2 areas:

- Monitoring in Intrinsically Safe areas:

Best - High precision and long experience:
  • CMSS 793-EE (-FM, -CA) (fig 9)
  • CMSS 797-EE (-FM, -CA) (fig 10)
  • CMSS 793V-EE (-FM, -CA) (fig 11)
