Replacement & Compatibility FAQ
Q: Can I use the 330908-10-55-05-02-00 with a 3300 NSv Proximitor?
A: No. The 3300 XL probe is calibrated for the 3300 XL Proximitor. Using a mismatched driver will produce incorrect output voltages and may trigger false alarms.
Q: What is the difference between 330908 and 330905?
A: The 330905 is the 3300 NSv 8mm series with a different sensitivity curve. They are not interchangeable without recalibrating the driver.
Q: Is the 330908-10-55-05-02-00 ATEX certified?
A: Yes, ATEX and FM intrinsically safe certifications are available on specific variants. Confirm the suffix code or contact us for the certified datasheet.
Q: Can Konmask.com supply the complete 3300 XL system (probe + extension + Proximitor)?
A: Yes. We can quote the full measurement chain. Contact us with your system 1 rack slot and cable run distance.
Q: Do you accept returns or offer warranty?
A: We offer a 90-day warranty on all units. Defective items are replaced or refunded. See our Returns Policy for details.
