Replacement & Compatibility FAQ
Q: Can I use the 330905-00-20-10-02-00 with a 3300 XL driver?
A: No. The 3300 NSv and 3300 XL systems use different driver electronics and calibration curves. Mixing components will result in measurement errors.
Q: What is the difference between connector type 01 and 02?
A: The connector suffix (01 vs 02) refers to the physical connector style on the probe body. Verify your extension cable connector before ordering.
Q: Is this probe suitable for non-ferrous target materials?
A: Standard calibration is for AISI 4140 steel. For non-ferrous targets (e.g., titanium, aluminum), a special calibration is required — contact us for details.
Q: Can Konmask supply the complete 3300 NSv transducer system?
A: Yes. We can supply the probe, extension cable (330130 series), and driver (330180 series) as a matched set. Request a system quote via email.
Q: Do you offer expedited shipping?
A: Yes. DHL Express, FedEx International Priority, and UPS Worldwide Expedited are available. Contact us for rates.
