330930-060-11-00 6.0m FluidLoc Extension Cable

Introduction to the 330930-060-11-00

When vibration monitoring systems suffer signal degradation or cable failure, the 330930-060-11-00 from Bently Nevada provides a robust solution. This 3300 NSv extension cable is engineered to maintain signal integrity over its 6.0-meter (19.7 feet) length, ensuring accurate data transmission from the probe to the Proximitor sensor.

As part of the 3300 NSv series, this cable is built for demanding industrial environments. Its FluidLoc design with stainless steel armor offers mechanical protection, while the FEP insulation ensures stable electrical performance across a wide temperature range.

Key Features and Technical Specifications

The 330930-060-11-00 delivers consistent performance through precision-engineered components. Below are the critical specifications extracted from the datasheet:

• Cable Length: 6.0 meters (19.7 feet) – option 060
• Connector Option: FluidLoc cable with stainless steel armor, without FEP jacket, with connector protector (option 11)
• Extension Cable Material: 75 Ω coaxial, fluoroethylene propylene (FEP) insulated
• Operating Temperature: -51°C to +177°C (-60°F to +351°F)
• Shipping Weight: 1.5 kg
• Center Conductor DC Resistance: 0.220 Ω/m (0.067 Ω/ft)
• Shield DC Resistance: 0.066 Ω/m (0.020 Ω/ft)
• Capacitance: 69.9 pF/m (21.3 pF/ft) typical

The cable's 75 Ω impedance matches the 3300 NSv system requirements, minimizing signal reflections. The FEP insulation provides excellent dielectric properties and thermal stability, making it suitable for high-temperature applications.

Installation and Setup

Proper installation is critical for optimal performance. The extension cable length and the probe length, when added together, must equal the Proximitor Sensor total length. This ensures correct system calibration and accurate measurements.

Field wiring should use three-conductor shielded triad cable with a maximum length of 305 meters (1,000 feet) between the 3300 XL NSv Proximitor Sensor and the monitor. For connections, use wire sizes from 0.2 to 1.5 mm² (16 to 24 AWG), or 0.25 to 0.75 mm² (18 to 23 AWG) with ferrules. Follow the frequency response graphs (Figure 16 and Figure 17) to understand signal rolloff at high frequencies when using longer wiring lengths.

Maintenance and Reliability

Regular inspection of the cable and connectors is essential to prevent downtime. Check for physical damage to the stainless steel armor and ensure the connector protector remains intact. The gold-plated brass connectors resist corrosion, but periodic verification of secure mating is recommended.

The cable's operating temperature range of -51°C to +177°C allows deployment in extreme environments, from freezing outdoor installations to high-heat machinery areas. Its tensile strength of 220 N (50 lb) at the probe case and connectors ensures durability under mechanical stress.

Compatibility and Integration

This extension cable is designed for use with Bently Nevada 3300 NSv proximity systems. It connects the probe to the Proximitor sensor, which then transmits signals to monitoring equipment. The system length options of 5 or 7 meters (including the extension cable) provide flexibility for various machine configurations.

For installations requiring extended reach, the maximum field wiring length of 305 meters allows remote monitoring setups. Ensure the Proximitor sensor is mounted within the specified distance to maintain signal fidelity.

Troubleshooting Common Issues

Signal loss or erratic readings often result from incorrect cable length matching or damaged connectors. Always verify that the total probe plus extension cable length equals the Proximitor sensor's specified length. If using longer field wiring, consult the frequency response graphs to anticipate high-frequency rolloff.

If the cable is subjected to excessive bending or pulling, inspect the armor for kinks or breaks. Replace the cable if the center conductor resistance exceeds 0.220 Ω/m or the shield resistance exceeds 0.066 Ω/m, as this indicates internal damage.
