Replacement & Compatibility FAQ
Q: Can I use a 330903 probe instead of the 330904?
A: Yes — the 330903 and 330904 share the same electrical specifications. The primary difference is the cable jacket material. Confirm your environmental requirements before substituting.
Q: Is the /CN suffix version electrically identical to the standard version?
A: Yes. The /CN suffix denotes China-market regulatory compliance (CCC/CE labeling). Electrical and mechanical specifications are identical.
Q: What driver do I need for this probe?
A: The 330904 probe requires a Bently Nevada 3300 series driver/oscillator-demodulator (e.g., 330180 or 330185). It is not compatible with 3500 series proximitor drivers without an adapter.
Q: Can I extend the cable length?
A: Yes, using Bently Nevada 330780 series extension cables. Total system cable length (probe + extension) must not exceed the driver’s specified maximum.
Q: Do you provide a certificate of conformance?
A: Yes. A CoC and factory test report are included with every shipment upon request.
