Replacement & Compatibility FAQ
Q: Can I use a 3300 XL probe as a direct replacement for the 330910-00-04-05-01-CN?
A: The 3300 XL 8mm probe is the upgraded successor and is backward-compatible with most 3300 NSv drivers. Verify driver firmware version before substitution.
Q: Is the -CN suffix required for installations in China?
A: Yes. The CN suffix denotes compliance with Chinese ATEX/IECEx certification requirements. Non-CN variants may not meet local regulatory standards.
Q: What is the gap voltage for this probe?
A: Standard gap voltage is -10.0 VDC at the midpoint of the linear range (approximately 1.25 mm gap) when used with the 330180 driver.
Q: Can Epro PR6423 replace this probe?
A: The PR6423/010-100 is a functional equivalent in terms of sensitivity and tip diameter, but requires an Epro-compatible driver (CON021 series). It cannot be used directly with Bently Nevada 3300 drivers without signal conditioning.
Q: Do you offer calibration services?
A: We supply factory-calibrated OEM units. Third-party calibration services can be arranged upon request for in-service probes.
