Replacement & Compatibility FAQ
Q: Can I use the 330904-00-12-05-02-00 with a Bently Nevada 3500 monitor?
A: Yes. The 3300 NSv probe is fully compatible with the 3500 series monitors when paired with the correct 3300 XL driver/extension cable.
Q: What is the difference between 330903 and 330904 series probes?
A: The 330904 series features the NSv (Non-Standard voltage) output optimized for the 3300 XL system. The 330903 is the standard 3300 series probe with slightly different gap voltage characteristics.
Q: Can I replace the 330904-00-12-05-02-00 with an Epro PR6423?
A: Functionally similar, but you must verify sensitivity (7.87 V/mm vs 8.0 V/mm) and recalibrate your monitor’s gap voltage setpoints before substitution.
Q: Do you supply calibration certificates?
A: Yes. OEM calibration documentation is available upon request for all in-stock units.
Q: What is the minimum order quantity?
A: No minimum order quantity. Single units are available. Volume discounts apply for orders of 5+ units.
