Designed for high-reliability transmission of displacement signals in Turbine Supervisory Instrumentation (TSI) architectures, the Bently Nevada 330930-045-03-CN serves as the vital connection link between a 3300 NSv proximity probe and its matching proximitor sensor. This premium-grade coaxial cable is engineered specifically for applications with restricted installation clearances or small shaft diameters where standard proximity systems are incompatible. Constructed with a 75 ohm coaxial FEP insulation, the cable provides consistent electrical performance, shielding critical machinery health data from electromagnetic interference and harsh industrial environments.
This specific configuration features a 4.5-meter cable length, an unarmored outer design with integrated connector protectors to shield junctions from fluid ingress, and specialized country-specific agency certifications. By maintaining strict impedance matching across its entire length, it ensures maximum linearity and accuracy in dynamic vibration and position measurements.

It is critical to note that the 3300 NSv series is electrically and physically distinct from the standard 3300 XL 5mm or 8mm series. Extension cables designed for the 3300 XL system cannot be swapped with the 3300 NSv cables due to differences in nominal probe target sizes and electrical tuning parameters. Ensure that you are pairing this 4.5m extension cable with a 0.5m proximity probe to maintain the mandatory 5.0m overall system length calibrated for your specific proximitor model.
The -03 option designates an unarmored configuration. While FEP insulation offers superior chemical resistance to machine oils and coolants, this cable is susceptible to crushing or shearing if routed directly through high-traffic machine areas without conduit protection. In environments with heavy mechanical risk or dynamic physical wear, run this cable inside a dedicated protective flexible conduit to prevent signal interruptions or physical conductor breaks.
When joining the extension cable to the proximity probe, verify that the connector protectors are fully seated and free of dirt, oil, or condensation. A common commissioning error is allowing moisture into the coaxial junction, which degrades isolation resistance to the machine casing, causing ground loops and spurious vibration spikes. Use a high-quality connector insulation kit or silicone self-fusing tape to lock the connector protectors in place once connection torque is reached.
Inspect the coaxial connectors on both the probe lead and the 330930-045-03-CN extension cable for any physical damage, bent center pins, or oil residue. Clean with an approved contact cleaner if necessary.
Carefully thread the probe lead connector into the extension cable connector. Finger-tighten the coupling nut until a positive physical stop is reached. Do not use pliers, as this can crush the miniature coaxial fittings.
Slide the integrated connector protectors over the junction to seal the connection against mechanical stress and chemical ingress. Ensure a tight seal on both ends of the sleeve.
Route the cable back to the proximity sensor housing, maintaining a minimum bend radius of 25.4 mm (1.0 inch). Secure the cable using insulated tie wraps, ensuring there is no excess tension on the terminations.
