Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Steam & Gas Turbine Vibration Monitoring – The Bently Nevada 21504-12-28-10-02 continuously measures radial shaft vibration to detect unbalance, misalignment, or bearing wear in high-speed turbines, preventing catastrophic blade contact.
  • Axial Thrust Position on Centrifugal Compressors – This probe monitors thrust bearing wear by tracking shaft axial displacement, allowing operators to schedule maintenance before thrust collar contact occurs.
  • Rotor Eccentricity Measurement During Startup – Before a turbine reaches rated speed, the Bently Nevada 21504-12-28-10-02 detects rotor bow (eccentricity) to ensure slow-roll running eliminates thermal bending, thus avoiding start-up vibrations.
  • Pump & Electric Motor Shaft Vibration – For critical pumps and large motors, this probe provides API 670-compliant non-contact vibration data, enabling predictive maintenance and reducing unplanned outages.
  • Probe diameter: 8 mm.
  • Unthreaded length: 1.2 in (30.5 mm).
  • Overall case length: 2.8 in (71.1 mm).
  • Integral cable length: 1.0 m (39 in).
  • Use with a compatible Bently Nevada 7200 Proximitor and extension-cable configuration.
  • Verify the complete transducer-system length before replacement.
  • The complete system supports non-contact shaft vibration and position measurement.
  • Do not substitute 3300 XL components without documented system compatibility.
