Vibration Monitoring Solution – Bently Nevada 330930-045-03-05 | 3300 NSv Series
Where This Product Is Used
The Bently Nevada 330930-045-03-05 Extension Cable is a precision-engineered interconnect component designed for continuous vibration and position monitoring in critical rotating machinery environments. Engineers specify this cable in the following industrial applications:
- Gas & Steam Turbines – Extends proximity probe signal paths in turbine bearing housings where direct monitor mounting is impractical.
- Centrifugal Compressors – Used in API 670-compliant shaft radial vibration and axial position measurement loops.
- Pumps & Fans – Connects eddy-current probes to 3300 NSv monitors in balance-of-plant rotating equipment.
- Marine Propulsion Systems – Deployed in shipboard machinery protection systems requiring compact, shielded cabling.
- Power Generation – Integrated into DCS-linked machinery protection panels at nuclear and thermal power stations.
- Petrochemical & Refinery Plants – Installed in hazardous-area proximity probe loops per IEC 60079 zone requirements.

Why Engineers Specify This Model
- System-Matched Performance – Factory-calibrated to work exclusively within the 3300 NSv transducer system, ensuring linear output across the full measurement range without field recalibration.
- Compact 45 cm Length – Ideal for tight machinery skid installations where longer cables introduce unnecessary signal attenuation or routing complexity.
- Shielded Coaxial Construction – Minimizes EMI/RFI interference in electrically noisy plant environments (VFD-driven equipment, switchgear rooms).
- API 670 Compatibility – Meets the interconnect requirements of the machinery protection standard adopted by EPC contractors and end-users globally.
- Drop-In Replacement – Direct OEM replacement; no firmware changes or monitor reconfiguration required.
Complete System Bill of Materials
The 3300 NSv proximity transducer system consists of three matched components. Ensure all three share the same system designation:
- Proximity Probe – e.g., Bently Nevada 330780-50-00 (8 mm, 5 m cable)
- Extension Cable – 330930-045-03-05 (this item, 45 cm)
- Proximitor® Sensor / Driver – e.g., Bently Nevada 330930 series driver module
- Monitor – 3300/16 or 3500/40M Proximitor® Monitor (rack-mounted)
Note: Mixing NSv and standard-voltage components will result in measurement errors. Always verify system compatibility before ordering.

Application-Specific FAQ
Q: Can I use this extension cable with a standard 3300 (non-NSv) probe?
A: No. The 3300 NSv system uses a different voltage supply rail (–18 V vs. –24 V). Mixing components will produce out-of-range output signals and may damage the Proximitor driver.
Q: What is the maximum total cable length for a 3300 NSv system?
A: Bently Nevada specifies a maximum combined probe + extension cable length. Consult the 3300 NSv system TDI (Technical Data Information) sheet for your specific probe tip diameter and gap range.
Q: Is this cable suitable for use in a classified hazardous area (Zone 1/Zone 2)?
A: The 3300 NSv system can be configured for intrinsically safe (IS) operation with appropriate barriers. Verify the full loop IS certification before installation in classified areas.
Q: Do you offer calibration certificates?
A: Factory calibration data is embedded in the system matching. Individual cable calibration certificates are not issued by Bently Nevada for extension cables. Contact us if your site QA requires additional documentation.
Q: What is the lead time for this part?
A: Standard lead time is 3–7 business days for in-stock units. Critical/AOG orders can be expedited — contact us directly.
