Overview of the 330930-065-06-CN
When vibration monitoring demands precision, the 330930-065-06-CN from Bently Nevada delivers a robust link between probe and Proximitor. This 3300 NSv extension cable is built for harsh industrial environments. It offers a 6.5-meter (21.3 feet) length, ensuring flexible routing. The FluidLoc design without stainless steel armor simplifies installation in confined spaces.

Key Features and Technical Specifications
This extension cable maintains signal integrity over its full length. Its 75 Ω coaxial construction uses fluoroethylene propylene (FEP) insulation. This material withstands extreme temperatures from -51°C to +177°C (-60°F to +351°F). The cable's center conductor has a DC resistance of 0.220 Ω/m (0.067 Ω/ft). The shield offers 0.066 Ω/m (0.020 Ω/ft) resistance. Capacitance is 69.9 pF/m (21.3 pF/ft) typical, preserving signal quality.

Connector and Agency Approvals
The connector uses gold-plated brass for reliable contact. The agency approval option CN indicates country-specific approvals. This ensures compliance with regional standards.
Installation and Setup
Proper installation is critical for accurate readings. Ensure the extension cable length plus the probe length equals the Proximitor total length. This maintains the correct gap setting of 1.0 mm (40 mils). Field wiring should use a three-conductor shielded triad cable. The maximum distance between the Proximitor and monitor is 305 meters (1,000 feet). For longer runs, consult the frequency response graphs to account for signal rolloff.

Maintenance and Reliability
Regular inspection of the cable and connectors prevents downtime. Check for physical damage, especially at connection points. The FEP insulation resists chemicals and moisture. The tensile strength is rated at 220 N (50 lb) at the probe case and connectors. This robust design extends service life. Follow the manufacturer's manual for detailed maintenance procedures.
Compatibility and Integration
This extension cable is part of the 3300 NSv system. It works with Bently Nevada proximity probes and Proximitor sensors. The 75 Ω impedance matches standard monitoring systems. Use it with the 3300 XL NSv Proximitor for optimal performance. The linear range is 1.5 mm (60 mils), starting at 0.25 mm (10 mils) from the target. This provides a usable range from 0.25 to 1.75 mm (10 to 70 mils), corresponding to approximately -1 to -13 Vdc.
Troubleshooting Common Issues
Signal loss often results from incorrect cable length or poor connections. Verify the total length matches the Proximitor requirement. Check connector tightness and cleanliness. If readings are erratic, test the cable's DC resistance. Compare with the specified values: 0.220 Ω/m for the center conductor and 0.066 Ω/m for the shield. High resistance indicates a break or corrosion. Replace the cable if damage is found.
