Replacement & Compatibility FAQ
Q: Can I use 330908-00-15-70-02-05 to replace a 330905 series probe?
A: The 330905 uses a 5 mm tip vs. the 330908’s 8 mm tip. They are not directly interchangeable without modifying the probe holder and recalibrating the gap voltage. Contact us for guidance.
Q: Is this probe compatible with the Bently Nevada 3500/42M monitor?
A: Yes. The 330908-00-15-70-02-05 is fully compatible with the 3500/42M Proximitor Monitor when paired with the correct 330180 driver and within the 9 m total cable length limit.
Q: Can a third-party probe (e.g., Epro PR6423) replace this unit?
A: Third-party probes may be electrically compatible but require system reconfiguration and validation. We recommend OEM parts for API 670 certified installations. We can supply both options.
Q: What is the gap voltage for this probe?
A: The nominal gap voltage is −10 VDC at the midpoint of the linear range (approximately 1.27 mm / 50 mil gap). Refer to the Bently Nevada 3300 XL 8 mm system datasheet for full calibration curves.
Q: Do you provide calibration certificates?
A: Yes. Calibration certificates and certificates of conformance are available upon request for all new OEM units.
