Compatible Replacement & Equivalent Models
The following models are commonly evaluated as direct or near-equivalent replacements for the 330904-00-17-05-02-00. Always verify system driver/conditioner compatibility before substitution.
- Bently Nevada 330903-00-17-05-02-00 — Standard NSv probe, same geometry, different sensitivity calibration
- Bently Nevada 330905-00-17-05-02-00 — Extended temperature variant, same series
- Emerson 330104-00-17-05-02-00 — OEM-equivalent under Emerson branding post-acquisition
- EPRO PR6423/010-040 — Third-party eddy-current probe, API 670 compliant, compatible with 3300 drivers
- Metrix ST5484E — Alternative eddy-current proximity probe for turbomachinery
- Wilcoxon Research 786A — Suitable for lower-frequency vibration monitoring applications
Note: Replacement compatibility depends on the paired driver/conditioner (e.g., 3300 XL 8mm, 3300 NSv driver). Contact support@konmask.com for a verified compatibility check.

Replacement & Compatibility FAQ
Q: Can I use a 330903 probe in place of the 330904?
A: The 330903 and 330904 share the same physical form factor but differ in sensitivity calibration. Substitution is possible only if the driver/conditioner is reconfigured accordingly.
Q: Is this probe compatible with the Bently Nevada 3500 rack?
A: Yes, when paired with the correct 3300 NSv driver module installed in the 3500 rack.
Q: Do you supply the extension cable separately?
A: Yes. Please specify the required length when ordering. Standard lengths: 5 m, 9 m, 15 m.
Q: Can you provide a new vs. refurbished option?
A: Both new and tested-surplus units are available. Specify your preference when requesting a quote.
Q: What is the lead time?
A: In-stock units ship within 3–5 business days. Special configurations may require 2–4 weeks.
