Features:
- 8 mm standard-mount proximity probe for a 7200 transducer system.
- 3/8-24 threaded case with 1.2-inch unthreaded length and 2.8-inch case length.
- 1.0 m integral cable with miniature male coaxial connector.
Bently Nevada 21504-12-28-10-02 is selected as part of a compatible 7200 proximity transducer system for non-contact shaft vibration and position measurement.
The probe dimensions, cable length, connector, matching extension cable, and Proximitor configuration must be verified together.
Current OEM lifecycle classification is not stated in the available Bently Nevada documentation. Availability is confirmed during quotation.

- 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.
