Replacement & Compatibility FAQ
Q: Can I use the 330903-00-16-10-02-05/CN with a 3500 monitoring rack?
A: Yes, provided the correct 3300 NSv Proximitor driver is used. The 3500 rack accepts 3300 NSv transducer inputs via compatible I/O modules.
Q: What is the difference between the /CN suffix and the standard model?
A: The /CN suffix denotes the China-manufactured variant. Electrically and mechanically, it meets the same Bently Nevada specifications as the standard model.
Q: Can I replace this probe with an 8 mm probe?
A: Not directly. An 8 mm probe has a different linear range and sensitivity. The driver, gap setting, and mounting hardware must all be updated accordingly.
Q: Do you offer calibration certificates?
A: Yes. Factory calibration data and CoC documents are available upon request for verified original units.
Q: What is the lead time?
A: In-stock items ship within 1–3 business days. For sourced or surplus units, typical lead time is 5–15 business days. Contact us for current availability.
