Bently Nevada 30004-02-12-18-02 Extension Cable 4.5m

Bently Nevada 30004-02-12-18-02 Extension Cable

The Bently Nevada 30004-02-12-18-02 is a 4.5-meter (14.8 ft) extension cable specifically designed for the 3300 series proximity transducer system. This cable enables flexible installation configurations while preserving the precision and reliability that Bently Nevada monitoring systems are known for.

What Makes This Cable Essential

In industrial monitoring installations, the distance between your proximity probe and the proximitor module rarely matches standard cable lengths. The 30004-02-12-18-02 solves this common challenge by providing exactly 4.5 meters of additional reach—a length that's proven optimal for most panel-to-machine configurations without introducing signal degradation.

Where It Fits In Your System

This extension cable integrates seamlessly between your proximity probe's integral cable and the proximitor input. It's particularly valuable in retrofit projects where existing conduit runs dictate specific cable routing, or in new installations where control panels are positioned for operator accessibility rather than proximity to the machinery.

The 4.5-meter length is strategically chosen—long enough to span typical floor-to-panel heights plus horizontal routing, yet short enough to maintain the low capacitance critical for accurate proximity measurements. Multiple cables can be daisy-chained if greater distances are required, though total system cable length should remain within manufacturer specifications (typically 9 meters maximum).

Installation Best Practices

Routing Considerations: Route cables away from high-voltage power lines, VFD cables, and welding equipment to minimize electromagnetic interference. Use metal conduit where possible for additional shielding.

Connection Integrity: Hand-tighten BNC connectors firmly—over-torquing can damage the center pin, while loose connections introduce noise and intermittent faults.

Strain Relief: Secure cables at regular intervals to prevent mechanical stress on connectors. Avoid sharp bends that exceed the minimum bend radius specification.

Documentation: Label both ends of the cable with the measurement point identifier to simplify future troubleshooting and maintenance.

Quality You Can Trust

Every Bently Nevada cable undergoes factory testing for capacitance, impedance, and shielding effectiveness. The 30004-02-12-18-02 meets or exceeds API 670 requirements for machinery protection systems, ensuring your monitoring data remains accurate and reliable throughout the cable's service life.

Condition: Brand new, factory-sealed with full manufacturer warranty and compliance documentation.
