Application Insights
The Bently Nevada 330730-040-00-CN excels in rotating machinery monitoring. In turbine installations, its low capacitance preserves signal quality over the 4-meter run, while the optional stainless steel armor protects against abrasion. For oil-lubricated systems, the FluidLoc cable option prevents leaks. The connector protector accessory adds moisture resistance in humid environments.
Installation & Setup Guidance
Each 330730-040-00-CN includes silicone tape for sealing probe-to-cable connections. For permanent installations, use the connector protector (recommended). Ensure cable routing avoids sharp bends and excessive tension. The triaxial design requires proper grounding per Bently Nevada guidelines. Max field wiring length to the proximitor is 305 meters (1,000 feet) using shielded triad cable.
Compatibility & Integration
This extension cable is part of the 3300 XL system, compatible with all 3300 XL Proximitor sensors and probes. It works with standard 5-meter or 9-meter system lengths. Use with Bently Nevada monitors and software for seamless data acquisition.
Selection Guide & Purchasing Advice
When ordering the Bently Nevada 330730-040-00-CN, verify cable length and armor requirements. The 330730-040-00-CN is a standard 4.0m non-armored version. For armored needs, specify the flexible SST option. For reliable supply, visit UBEST Automation at ubest101.myshopify.com. We stock genuine Bently Nevada parts with fast shipping.
