330930-065-03-CN 6.5m Bently Nevada Extension Cable

Introduction to the 330930-065-03-CN

When you need a dependable link between your 3300 XL NSv Proximitor Sensor and probe, the 330930-065-03-CN from Bently Nevada delivers the precision and durability your machinery monitoring demands. This 3300 NSv extension cable is engineered for harsh industrial environments, offering a robust solution for accurate vibration and position measurements.

Key Features and Technical Specifications

The 330930-065-03-CN is built with a 75 Ω coaxial, fluoroethylene propylene (FEP) insulated design, ensuring signal integrity over its 6.5-meter (21.3 feet) length. This extension cable is available without stainless steel armor but includes a connector protector, safeguarding the connection in demanding settings. It operates reliably across a wide temperature range of -51°C to +177°C (-60°F to +351°F), making it suitable for extreme conditions.

• Cable length: 6.5 meters (21.3 feet)
• Connector option: Without stainless steel armor, with connector protector
• Extension cable material: 75 Ω coaxial, FEP insulated
• Operating and storage temperature: -51°C to +177°C (-60°F to +351°F)
• Shipping weight: 1.5 kg
• Center conductor DC resistance: 0.220 Ω/m
• Shield DC resistance: 0.066 Ω/m

This cable is designed to work seamlessly with the 3300 XL NSv system, ensuring that the extension cable length plus the probe length equals the Proximitor Sensor total length for optimal performance.

Applications and Use Cases

In rotating machinery monitoring, the 330930-065-03-CN is essential for connecting sensors in turbines, compressors, and pumps. Its FEP insulation provides excellent resistance to moisture and chemicals, making it ideal for oil and gas, power generation, and petrochemical facilities. The cable's robust construction minimizes signal loss, ensuring accurate data transmission for predictive maintenance programs.

Installation and Setup

When installing the 330930-065-03-CN, ensure the cable length and probe length sum correctly to match the Proximitor Sensor total length. The cable supports field wiring of 0.2 to 1.5 mm² (16 to 24 AWG), with a recommendation for three-conductor shielded triad cable. For best performance, keep the distance between the Proximitor Sensor and the monitor within 305 meters (1,000 feet) to avoid signal rolloff at high frequencies.

Maintenance and Reliability

Regular inspection of the cable and connectors is recommended to maintain signal integrity. The FEP insulation and gold-plated brass connectors resist corrosion, extending the cable's service life. In extreme temperatures, the cable's wide operating range ensures consistent performance, reducing downtime and maintenance costs.

Compatibility and Integration

The 330930-065-03-CN is part of the Bently Nevada 3300 NSv system, designed for seamless integration with 3300 XL NSv Proximitor Sensors and compatible monitors. This ensures reliable vibration monitoring across your critical assets.

Troubleshooting and Common Issues

If you experience signal loss or erratic readings, first verify that the cable length and probe length are correctly matched to the Proximitor Sensor total length. Check all connections for tightness and corrosion. For detailed diagnostics, refer to the frequency response graphs in the official documentation to understand signal rolloff at longer field wiring lengths.
