Replacement & Compatibility FAQ
Q: Can I use a 330876-01-60-00-00 instead of the 330876-01-90-00-00?
A: Yes, if the shorter cable length suits your installation geometry. The probe and driver remain identical; only the extension cable length differs.
Q: Is the Epro PR6423 a direct drop-in replacement?
A: Electrically compatible with most 3300/3500 monitors, but requires recalibration of the monitor channel. Not recommended for API 670-certified systems without engineering review.
Q: Does Konmask.com supply the complete transducer system (probe + extension + driver)?
A: Yes. We can supply individual components or complete matched sets. Please specify your requirements when inquiring.
Q: What is the lead time?
A: In-stock units ship within 3–5 business days. Ex-stock or special configurations may require 2–4 weeks.
