Bently Nevada 330130-045-01-00 3300 XL Standard Extension Cable

Essential Interconnect for Proximity Monitoring Systems

The Bently Nevada 330130-045-01-00 standard extension cable links the proximity probe to the Proximitor for continuous signal transmission. This 8 mm system cable spans 4.5 meters and employs a robust coaxial design to preserve signal quality. Its fluoropolymer jacket resists oils, hydraulic fluids, and abrasion, making it ideal for harsh industrial settings. Both ends incorporate standard connectors for quick installation and reliable mating. This cable plays a vital role in maintaining accurate vibration measurements across critical turbomachinery.

Signal Integrity and Thermal Endurance

This extension cable exhibits a capacitance of 160 pF per meter with a characteristic impedance of 50 Ω. The conductor resistance stays below 0.5 Ω per meter, minimizing signal loss over the cable’s length. It operates across a wide temperature span from -51°C to +260°C, matching the thermal ratings of 3300 XL probes. The braided copper shielding effectively rejects electromagnetic noise from surrounding equipment. These electrical characteristics guarantee clean signal transfer for precise displacement readings.

Detailed Technical Specifications

Connector Configuration and Compatibility

This extension cable provides a male BNC connector at one end for direct Proximitor attachment. The opposite end features a female coaxial connector that matches standard Bently Nevada probe connectors. The locking mechanism ensures a secure connection that resists loosening from vibration and thermal cycling. The cable stores no internal energy, supporting intrinsic safety for hazardous area installations. Operators can use this cable with 3300 XL 8 mm probes and the 3500 Monitoring System without additional adapters.

Installation and Handling Considerations

Installing this extension cable requires routing it through cable trays or conduit with a minimum bend radius of 25 mm. The connectors tighten securely using a standard 5/16-inch wrench to ensure proper mating. Regular inspections of the cable jacket will identify cuts or wear that could compromise signal fidelity. Operators should avoid sharp bends and excessive pulling forces during installation to extend cable life. This component needs no routine maintenance, though annual checks of connector cleanliness and tightness remain advisable.
