Replacement & Compatibility FAQ
Q: Can I use an Epro probe as a direct replacement?
A: Epro PR6423 series probes are electrically compatible with most 3300 drivers, but sensitivity curves differ. Recalibration of the driver gap voltage is required.
Q: What is the difference between 330904 and 330900?
A: The 330904 is the NSv (Non-Standard voltage) variant optimized for -24 VDC systems. The 330900 is the standard voltage version. Confirm your driver supply voltage before substituting.
Q: Is this probe compatible with the Bently Nevada 3500 system?
A: Yes, when paired with the appropriate 3300 NSv driver module installed in the 3500 rack.
Q: Do you offer expedited shipping?
A: Yes. DHL Express and FedEx International Priority are available. Contact us for a quote.
Q: Can you supply calibration documentation?
A: Yes, calibration certificates are included with new units and available on request for surplus stock.
