Turbine Vibration Monitoring Solution – Bently Nevada 330930-045-04-05 | 3300 XL NSv Series
Where This Product Is Used
The Bently Nevada 330930-045-04-05 is a 3300 XL NSv Extension Cable (4.5 m / 15 ft) engineered for continuous-duty vibration and position monitoring in rotating machinery environments. It is routinely specified in the following industrial applications:
- Gas & Steam Turbines – Connects proximity probes to 3300 XL monitors for shaft radial vibration and eccentricity measurement on power-generation turbines.
- Centrifugal Compressors – Provides the signal path between probe tip and monitor rack in high-pressure compressor trains on oil & gas platforms and refineries.
- Pumps & Fans – Used in balance-of-plant rotating equipment where API 670 compliance is required.
- Marine Propulsion Systems – Deployed in shipboard machinery rooms where cable routing demands a mid-length extension.
- Petrochemical & LNG Plants – Installed in hazardous-area installations requiring intrinsically safe signal cables.
The 4.5 m length fills the gap between the standard probe armored cable and the monitor rack, making it the most commonly ordered extension length in the 3300 XL NSv system.

Why Engineers Specify This Model
- System-Matched Performance – Designed exclusively for the 3300 XL NSv probe/driver ecosystem; impedance and capacitance are factory-tuned to maintain ±1% linearity across the full gap range.
- 4.5 m Sweet Spot – The most versatile extension length: long enough to reach monitor racks mounted away from bearing housings, short enough to avoid signal attenuation issues.
- Rugged Construction – Armored outer jacket resists oil, coolant, and mechanical abrasion in turbine halls and compressor buildings.
- API 670 Compliance – Meets the international standard for machinery protection systems, satisfying EPC contractor and end-user specifications without additional qualification.
- Drop-In Replacement – Identical form, fit, and function to the OEM cable; no recalibration of the monitor system required after installation.

Application-Specific FAQ
Q: Can I use the 330930-045-04-05 with older 3300 (non-XL) probes?
A: No. The NSv extension cable is designed for the 3300 XL NSv system. Using it with legacy 3300 probes may cause calibration errors. Verify your probe part number before ordering.
Q: What is the total system cable length when combined with a standard probe?
A: A 5 m probe cable + 4.5 m extension = 9.5 m total. The 3300 XL NSv system supports total cable lengths up to 9 m or 15 m depending on driver configuration — confirm with your system datasheet.
Q: Is this cable suitable for hazardous area (Zone 1 / Zone 2) installations?
A: The cable itself is passive; hazardous-area suitability depends on the associated Proximitor driver’s ATEX/IECEx certification. Consult the driver datasheet and your site safety authority.
Q: Do you offer other lengths in the 330930 series?
A: Yes. Common alternatives include 330930-020-04-05 (2 m), 330930-060-04-05 (6 m), and 330930-090-04-05 (9 m). Contact us for availability.
Q: Can Konmask provide a certificate of conformance?
A: Yes, a CoC is available upon request at no additional charge.
