Replacement & Compatibility FAQ
Q: Can I use a standard (Stdv) 3300 XL probe instead of the NSv version?
A: No. NSv and Stdv probes use different driver electronics and are not interchangeable without re-characterizing the system. Always match probe and driver series.
Q: What is the difference between 330905 and 330103?
A: The 330103 is a 5 mm probe; the 330905 is an 8 mm probe. They have different linear ranges and sensitivity values and are not directly interchangeable.
Q: Can Epro PR6423 replace the 330905-08-13-10-02-05?
A: Functionally similar, but requires an Epro driver system. It cannot be used with Bently Nevada NSv drivers without system modification.
Q: Do you offer exchange or repair services?
A: Yes. Contact us for repair assessment and exchange program availability.
Q: Is this probe suitable for hazardous areas?
A: Yes, subject to ATEX/IECEx zone ratings. Confirm the specific approval code on the probe label matches your installation zone requirements.
