Replacement & Compatibility FAQ
Q: Can I use the 330903-00-06-05-01-00 with a Bently Nevada 3500 monitor?
A: Yes. The 3300 XL NSv system is compatible with 3500/42M and 3500/40M proximity monitor modules when configured for NSv input.
Q: What is the difference between NSv and standard 3300 XL probes?
A: NSv (Non-Standard voltage) probes operate at a different bias voltage and scale factor (~200 mV/mil vs. ~100 mV/mil for standard). Mixing types without reconfiguring the monitor will cause measurement errors.
Q: Is the EPRO PR6423 a drop-in replacement?
A: Functionally similar, but the PR6423 uses a different connector and may require an adapter cable. Verify monitor input configuration before substituting.
Q: Do you supply calibration certificates?
A: Yes, calibration reports are available upon request for an additional fee. Contact us at the time of order.
Q: Can this unit be repaired if damaged?
A: Proximity transducer systems are generally not field-repairable. Replacement is the standard practice per API 670 guidelines.
