Selection Guide
Use the following criteria to confirm the 330910-06-25-05-11-00 is the right probe for your application:
- Cable length required: 6 m integral — if longer runs are needed, add extension cable (330130-xx-xx)
- Tip diameter: 25 mm — suitable for shaft diameters ≥ 50 mm per API 670 guidelines
- Target material: Optimized for AISI 4140; for stainless or titanium shafts, request a material-specific calibration
- Driver pairing: Must be used with a Bently Nevada 3300 NSv driver for factory-spec performance
- Environment: Confirm ATEX zone classification if installing in hazardous areas
- Measurement type: Radial vibration or axial position — both supported within the 0.25–2.54 mm linear range

Replacement & Compatibility FAQ
Q: Can I use a 330905 series probe as a direct replacement?
A: The 330905 (8 mm tip) has a different linear range and sensitivity curve. It is not a drop-in replacement without driver reconfiguration and gap re-setting.
Q: Is the 330910-06-25-05-11-00 compatible with the Bently Nevada 3500 system?
A: Yes, when paired with the appropriate 3300 NSv driver module within the 3500 rack. Confirm the driver card part number before ordering.
Q: Can Epro PR6423 probes replace this unit?
A: Functionally similar, but the Epro probe requires its own CON021/CON041 driver. Mixing probe and driver brands without recalibration will produce inaccurate readings.
Q: What is the shelf life of an unused probe?
A: Bently Nevada recommends storage in original packaging at 15–35 °C, away from moisture and magnetic fields. Properly stored units remain serviceable for 5+ years.
Q: Do you provide calibration certificates?
A: Yes. OEM calibration documentation is available for new units. For surplus stock, third-party calibration reports can be arranged upon request.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical lead time is 2–6 weeks depending on sourcing channel. Contact us for current availability.
