Replacement & Compatibility FAQ
Q: Can I replace 330905-00-18-50-02-00 with a different cable length variant?
A: Yes, if the installation space allows. The probe tip and electrical characteristics are identical across cable length variants. Verify conduit routing before ordering.
Q: Is the Epro PR6423 a drop-in replacement?
A: Electrically compatible in most cases, but requires driver reconfiguration. Not recommended for API 670-certified systems without engineering review.
Q: Does Konmask.com provide calibration certificates?
A: Yes, calibration certificates and test reports are available for new OEM units. Contact us for details on surplus stock documentation.
Q: What is the lead time for this part?
A: In-stock units ship within 1–3 business days. Out-of-stock orders typically have a 2–6 week lead time depending on sourcing channel.
Q: Can this transducer be used with a non-Bently Nevada monitor?
A: Yes, with appropriate signal conditioning. The −24 VDC supply and voltage output are standard eddy-current interface signals compatible with most third-party monitors.
