The 330930-065-02-CN is a specialized 3300 NSv (Narrow Side view) extension cable designed by Bently Nevada for high-precision proximity transducer systems. The NSv series is specifically engineered for applications where structural constraints or small shaft diameters require a sensor with a narrow magnetic field. This cable acts as the vital signal link between the proximity probe and the Proximitor sensor, maintaining the tuned electrical impedance necessary for accurate vibration and position monitoring. Commonly deployed in centrifugal compressors, small steam turbines, and aero-derivative gas turbines, the 330930-065-02-CN ensures that high-frequency eddy-current signals are transmitted with minimal attenuation, directly contributing to machine safety and the prevention of costly unplanned outages.
The model 330930-065-02-CN is defined by its mechanical protection and regional certification options:
330930: 3300 NSv Extension Cable series.
065: Cable Length Option - 6.5 meters (21.3 feet).
02: Connector and Cable Option - Equipped with stainless steel armor for superior mechanical protection, without an external FEP jacket over the armor.
CN: Agency Approval Option - Country-specific approvals for the China market, ensuring compliance with local industrial safety and hazardous area standards.

Can I use this NSv extension cable with a standard 3300 XL 8 mm probe?
No. The 3300 NSv system has different electrical characteristics (inductance and capacitance) compared to the 3300 XL series. Mixing NSv cables with XL probes will result in incorrect scale factors and significant measurement errors. Always match the cable series to the probe and Proximitor type.
What is the benefit of the stainless steel armor (Option 02)?
The stainless steel armor provides robust protection against physical damage such as crushing, abrasion, or accidental cutting in harsh industrial environments. It is ideal for installations where the cable is exposed rather than housed in a dedicated conduit.
How does the total system length affect calibration?
Bently Nevada proximity systems are tuned to specific total electrical lengths (typically 5 or 9 meters). This 6.5-meter cable must be combined with a probe of the correct lead length to reach the total system length required by the Proximitor sensor. Failure to match these lengths will compromise calibration accuracy.
Connector Handling: The miniature coaxial connectors are precision components. Use a connector protector if the junction is located in an area exposed to oil or moisture. Ensure the "ClickLoc" mechanism is fully engaged; you should feel a tactile click when the connection is secure.
Minimum Bend Radius: Even with stainless steel armor, do not exceed the minimum bend radius of 25.4 mm (1.0 inch). Sharp bends can damage the internal coaxial dielectric, leading to signal noise or a "Not OK" status on the monitoring rack.
Armor Grounding: Ensure the stainless steel armor is not inadvertently grounded at multiple points, as this can create ground loops that introduce electrical interference into the vibration signal. The system is typically grounded only at the Proximitor sensor end.
Armor vs. Jacket: Since this model (Option 02) does not have an FEP jacket over the armor, avoid routing the cable through areas where corrosive chemicals could penetrate the stainless steel braid and attack the internal cable insulation.
