- Bently Nevada 330703-000-060-10-02-CN 3300 NSv Extension Cable
SKU: 330703-000-060-10-02-CN
Bently Nevada 330703-000-060-10-02-CN 3300 NSv Extension Cable
The Bently Nevada 330703-000-060-10-02-CN is a 6.0-meter extension cable designed for the 3300 NSv Proximity Transducer System. It facilitates high-accuracy vibration monitoring in confined spaces, featuring ClickLoc connectors and a rugged FEP jacket capable of withstanding temperatures up to +177°C.
Technical Function and System Role
The Bently Nevada 330703-000-060-10-02-CN serves as the vital link between a 3300 NSv proximity probe and a 3300 NSv Proximitor Sensor. As a specialized extension cable, it maintains the precise electrical impedance required to transmit high-frequency eddy current signals without distortion. The 3300 NSv (Near Surface) system specifically addresses applications with small target sizes or confined installation spaces where standard 8mm probes cannot function effectively. By using this cable, operators ensure the integrity of vibration and position data for critical rotating assets.

Component Applications and Benefits
Maintenance professionals deploy the 330703 extension cable primarily in centrifugal compressors, small pumps, and aero-derivative gas turbines. Because the NSv system excels at monitoring small shafts (diameters less than 50mm), this cable provides the necessary reach from the machine case to the monitoring rack. Furthermore, the ClickLoc connectors feature a “positive lock” mechanism that prevents disconnection due to industrial vibration. The FEP (Fluorinated Ethylene Propylene) outer jacket offers superior resistance to corrosive fluids, lubricating oils, and extreme thermal cycling.
Installation Guidelines
System accuracy depends entirely on matching the total electrical length of the probe and extension cable to the Proximitor Sensor’s calibration (typically 5.0 or 7.0 meters). For the 330703-000-060-10-02-CN, engineers must verify that the combined length of the probe lead and this cable adheres to the 3300 NSv system requirements. Additionally, the use of connector protectors is highly recommended for any junction located inside a machine housing to prevent oil contamination from grounding the signal.
