Bently Nevada 330903-00-04-10-02-05/CN Proximitor Extension Cable – 3300 NSv Series
Imagine a critical rotating machine — a turbine, compressor, or pump — running at full load in your facility. The proximity probe is in place, the Proximitor sensor is mounted, but the signal never reaches the monitoring system. Without a properly specified, OEM-grade extension cable like the Bently Nevada 330903-00-04-10-02-05/CN, the entire vibration monitoring chain breaks down. Shaft displacement data is lost, early-warning alarms go silent, and the risk of catastrophic, unplanned downtime rises dramatically. This single cable is the invisible backbone of your machine protection system.
The 330903-00-04-10-02-05/CN is a factory-specified extension cable within the Bently Nevada 3300 NSv (Non-Standard Voltage) Series — one of the most widely deployed proximity transducer systems in global turbomachinery and rotating equipment monitoring. Engineered to maintain signal integrity across the full probe-to-monitor signal path, this cable variant is designed for installations requiring a specific cable length and connector configuration (CN suffix), making it a precision-matched component for OEM and retrofit applications worldwide.

Frequently Asked Questions
- Q: What does the /CN suffix mean on part number 330903-00-04-10-02-05/CN?
- A: The /CN suffix designates a specific connector configuration variant of the 330903 extension cable series. It is a factory-defined option code used by Bently Nevada to specify the cable assembly’s termination type. Always order using the exact full part number to ensure correct fit.
- Q: Is this cable compatible with the Bently Nevada 3500 monitoring system?
- A: The 330903-00-04-10-02-05/CN is part of the 3300 NSv transducer system. Compatibility with 3500 rack modules depends on the specific input card configuration. Please contact our technical team to confirm compatibility with your installed system.
- Q: Can I use a different length extension cable without recalibrating the system?
- A: No. The Bently Nevada 3300 NSv system is calibrated for a specific total cable length (probe cable + extension cable). Changing the extension cable length requires recalibration of the Proximitor sensor. Always replace with the identical part number.
- Q: What is the lead time for the 330903-00-04-10-02-05/CN?
- A: Lead time varies by current stock availability. Submit an inquiry and our team will confirm availability and estimated delivery within 1 business day.
- Q: Do you provide documentation or certificates of conformance?
- A: Yes. We can provide available sourcing documentation upon request. Please specify your documentation requirements when submitting your inquiry.
