Product Overview
The Bently Nevada 330930-060-00-CN is a 3300 NSv Extension Cable engineered for precision signal transmission in industrial vibration monitoring systems. This 6.0-meter (19.7 feet) cable ensures reliable connectivity between the probe and the Proximitor Sensor, maintaining signal fidelity over extended runs. Manufactured in the U.S.A., this extension cable features a 75 Ω coaxial construction with fluoroethylene propylene (FEP) insulation, providing excellent dielectric stability and resistance to harsh environments.
With a linear range of 1.5 mm (60 mils) and a recommended gap setting of 1.0 mm (40 mils), the 330930-060-00-CN supports accurate displacement measurements critical for rotating machinery health monitoring. The cable's gold-plated brass connectors ensure corrosion resistance and secure mating, while the optional stainless steel armor (not included in this variant) offers additional mechanical protection.
This extension cable is part of the 3300 NSv series, designed for seamless integration with Bently Nevada's proximity probe systems. Its FEP insulation and robust construction make it suitable for demanding industrial applications, including turbines, compressors, and pumps.

Industry Applications
The Bently Nevada 330930-060-00-CN extension cable is a critical component in vibration monitoring systems across various industries. Its robust design ensures reliable data transmission, which is essential for predictive maintenance and machine protection.
-
Rotating Machinery Monitoring: Used with proximity probes to measure shaft vibration and position in turbines, compressors, and generators, enabling early detection of mechanical faults.
-
Process Pumps: Supports continuous monitoring of pump health, reducing unplanned downtime and maintenance costs.
-
Industrial Fans and Motors: Provides accurate displacement data for balancing and alignment, extending equipment lifespan.
By maintaining signal integrity over long cable runs, the 330930-060-00-CN helps prevent false trips and ensures precise condition monitoring, directly contributing to operational efficiency.
Installation & Setup Guidance
Proper installation is crucial for optimal performance. Follow these guidelines when deploying the Bently Nevada 330930-060-00-CN extension cable.
-
Length Verification: Ensure the combined length of the extension cable and the probe equals the required Proximitor Sensor total length. Incorrect lengths will affect calibration.
-
Wiring Requirements: Use a three-conductor shielded triad cable for field wiring. The maximum allowable distance between the 3300 XL NSv Proximitor Sensor and the monitor is 305 meters (1,000 feet). Exceeding this may cause signal rolloff at high frequencies—refer to frequency response graphs for guidance.
-
Connector Care: Gold-plated brass connectors provide excellent conductivity but must be kept clean and free from debris. Use proper torque when tightening to avoid damage.
-
Environmental Considerations: The cable operates within -51°C to +177°C, making it suitable for extreme conditions. Avoid bending beyond the minimum bend radius to prevent insulation damage.
Maintenance & Reliability
Regular inspection of the extension cable and its connections can prevent unexpected failures. Check for signs of wear, especially at connector points, and ensure that protective coverings are intact. The FEP insulation offers high resistance to chemicals and temperature, but physical damage should be addressed immediately.
Because the 330930-060-00-CN is designed for long-term service, incorporating it into a routine maintenance schedule reduces the risk of downtime. The tensile strength rating of 220 N ensures durability, but avoid exceeding this limit during installation or maintenance activities.
Selection Guide & Purchasing Advice
When selecting an extension cable, verify the cable length and connector options match your system requirements. The '060' option indicates a 6.0-meter length, and '00' specifies no armor—confirm these align with your application environment. If additional mechanical protection is needed, consider a version with stainless steel armor.
