Applications
The Bently Nevada 330930-065-02-00 is ideal for connecting a 3300 XL NSv Proximitor Sensor to a monitor in critical rotating equipment such as turbines, compressors, and pumps. Its 75 Ω coaxial construction preserves signal integrity over the 6.5-meter length, ensuring precise vibration and position readings. The stainless steel armor protects against mechanical damage in harsh plant environments, reducing downtime and maintenance costs.
Installation Guidance
Ensure the extension cable length and probe length, when added together, equal the Proximitor Sensor total length. Route the cable away from high-voltage sources and sharp edges. Use the recommended field wiring (three-conductor shielded triad cable) for connections between the sensor and monitor, keeping total field wiring length within 305 meters (1,000 feet). Secure the cable with appropriate clamps to avoid stress on connectors.
Maintenance & Reliability
Regularly inspect the cable for cuts, abrasions, or damage to the armor. Check connector tightness to maintain a reliable electrical connection. The cable operates over a wide temperature range, making it suitable for extreme environments, but avoid exceeding the specified limits. Periodic testing of DC resistance and capacitance can verify cable health and prevent unexpected failures.
Compatibility & Integration
This extension cable is designed for use with the 3300 XL NSv Proximitor Sensor and compatible Bently Nevada monitors. It is not a standalone sensor; it must be paired with the appropriate probe and proximitor. Verify compatibility with your existing system before ordering.
Buying Guide
Before purchasing, confirm your required cable length and connector options. The 330930-065-02-00 is a specific configuration (6.5m, stainless steel armor, no FEP jacket). If you need a different length or armor type, please check other part numbers. For guaranteed quality and availability, consider PLC Source PRO as your trusted supplier for Bently Nevada components.
