Application-Specific FAQ
Q: Can this cable be used with older Bently Nevada 3300 (non-NSv) proximity probes?
A: No. The 330903 series is designed specifically for the 3300 NSv system. For legacy 3300 probes, use the 330130 series extension cable. Mixing cable series will result in calibration errors and incorrect gap voltage readings.
Q: What is the maximum total system cable length for the 3300 NSv?
A: Total cable length (probe integral cable + extension cable) must not exceed the system-specified maximum, typically 9 m (30 ft) for standard configurations. Verify your probe’s integral cable length before ordering.
Q: Is the /CN suffix a country-of-origin designation?
A: Yes. The /CN suffix indicates manufacture in China. The component meets the same OEM performance specification as non-suffixed variants. Verify import compliance requirements for your jurisdiction prior to ordering.
Q: Can I use this cable in a hazardous area (Zone 1 / Division 1)?
A: The 3300 NSv system has ATEX/IECEx certifications available for specific configurations. Consult the Bently Nevada 3300 NSv Installation Manual and your site’s area classification documentation. Contact us for certified-configuration sourcing.
Q: Do you supply the full 3300 NSv transducer loop?
A: Yes. Konmask.com can supply the complete loop including probe, extension cable, and proximitor. Contact support@konmask.com with your system requirements.
