Bently Nevada 330130-045-02-00 Extension Cable

Reliable Signal Transmission for Proximity Probe Systems

The Bently Nevada 330130-045-02-00 extension cable connects the proximity probe to the Proximitor sensor for uninterrupted signal transmission. This 8 mm system cable measures 4.5 meters in length and features a standard coaxial construction for optimal signal integrity. The cable incorporates a fluoropolymer jacket that resists oils, chemicals, and mechanical abrasion in harsh environments. Its connectors include a male BNC at one end and a female coaxial connector at the other for straightforward installation. This cable serves as a critical link between the probe and monitoring equipment in vibration protection systems.

Electrical Characteristics and Environmental Durability

This extension cable offers a capacitance of 160 pF per meter with an impedance of 50 Ω for consistent signal transfer. The cable maintains a conductor resistance of less than 0.5 Ω per meter, ensuring minimal signal attenuation over its 4.5 meter length. It operates across temperatures from -51°C to +260°C, matching the thermal capabilities of 3300 XL probes. The coaxial shielding provides effective protection against electromagnetic interference from nearby motors and power cables. Such characteristics preserve the signal-to-noise ratio for accurate vibration measurements.

Detailed Technical Specifications

Connection Interfaces and Compatibility

This extension cable features a male BNC connector at one end for direct attachment to the Proximitor sensor. The opposite end includes a female coaxial connector that mates with the standard Bently Nevada probe connector. The cable’s locking mechanism provides a secure connection that prevents accidental disconnection during operation. It stores negligible internal energy and poses no intrinsic safety concerns for hazardous locations. Users can pair this cable with 3300 XL 8 mm probes and the 3500 Monitoring System for complete vibration monitoring solutions.

Installation and Maintenance Guidance

Installing this extension cable requires routing the coaxial line through cable trays or conduit with a minimum bend radius of 25 mm. The connectors tighten by hand with a standard 5/16-inch wrench for secure mating. Regular visual inspections of the cable jacket will detect cuts or abrasion before they compromise signal quality. Operators should avoid sharp bends and excessive tension during installation to maintain long-term reliability. This cable requires no periodic maintenance, though users should inspect the connectors annually for corrosion or looseness.
