Buyer's Guide: Bently Nevada 330930-060-05-00 Extension Cable
When you need a dependable connection between a 3300 XL NSv Proximitor Sensor and its probe, the 330930-060-05-00 from Bently Nevada is a proven choice. This 3300 NSv extension cable delivers the electrical and mechanical performance required for continuous machinery protection. Its 6.0-meter length and stainless steel armor make it suitable for demanding industrial environments.
This buyer's guide helps you evaluate the 330930-060-05-00 against your specific requirements. We cover key specifications, installation considerations, and maintenance practices—all based on the manufacturer's published data.

Key Features and Technical Specifications
The 330930-060-05-00 is built to precise standards. Its 75 Ω coaxial construction with FEP insulation ensures signal integrity over the full cable run. The stainless steel armor provides mechanical protection without an FEP jacket, and a connector protector is included.
- Cable length: 6.0 meters (19.7 feet)
- Connector option: Stainless steel armor, no FEP jacket, with connector protector
- Extension cable material: 75 Ω coaxial, fluoroethylene propylene (FEP) insulated
- Center conductor DC resistance: 0.220 Ω/m (0.067 Ω/ft)
- Shield DC resistance: 0.066 Ω/m (0.020 Ω/ft)
- Extension cable capacitance: 69.9 pF/m (21.3 pF/ft) typical
- Operating and storage temperature: -51°C to +177°C (-60°F to +351°F)
- Shipping weight: 1.5 kg
These parameters directly affect measurement accuracy. The low DC resistance minimizes signal loss, while the controlled capacitance maintains consistent frequency response. The wide temperature range allows installation in harsh environments.
Applications and Use Cases
The 330930-060-05-00 is designed for use with Bently Nevada 3300 XL NSv proximity systems. It is commonly applied in rotating machinery monitoring, including turbines, compressors, and pumps. The extension cable connects the probe to the Proximitor Sensor, enabling accurate shaft vibration and position measurements.
Because the cable is armored, it suits installations where mechanical damage is a risk. The optional connector protector adds another layer of security. For new installations or retrofits, this cable helps maintain the integrity of the measurement chain.

Installation and Setup
Proper installation is critical for reliable operation. The manufacturer specifies that the extension cable length and the probe length, when added together, must equal the Proximitor Sensor total length. Verify this before installation.
Field wiring between the Proximitor Sensor and the monitor should use three-conductor shielded triad cable. The recommended wire size is 0.2 to 1.5 mm² (16 to 24 AWG). With ferrules, 0.25 to 0.75 mm² (18 to 23 AWG) is acceptable. The maximum field wiring length is 305 meters (1,000 feet).
When routing the extension cable, avoid sharp bends and excessive tension. The tensile strength rating is 220 N (50 lb) at the probe case to probe lead, probe lead to extension cable connectors, and probe case to stainless steel armor. Do not exceed these limits.
Maintenance and Reliability
The 330930-060-05-00 is designed for long service life. The FEP insulation and stainless steel armor resist moisture, chemicals, and mechanical wear. However, periodic inspection is recommended.
Check the cable for cuts, abrasions, or kinks. Verify that connectors are tight and free of corrosion. The gold-plated brass connectors offer excellent conductivity and corrosion resistance. If the cable is exposed to extreme temperatures, confirm that it remains within the -51°C to +177°C range.
Regular inspection helps prevent unexpected failures. A damaged cable can introduce noise or signal loss, leading to inaccurate measurements. By maintaining the cable, you protect your machinery monitoring investment.
Compatibility and Integration
The 330930-060-05-00 is part of the Bently Nevada 3300 NSv system. It is compatible with 3300 XL NSv Proximitor Sensors and associated monitors. The cable's 75 Ω impedance matches the system's requirements, ensuring proper signal transmission.
For integration, follow the system's installation manual. The linear range of the 3300 XL NSv system is 1.5 mm (60 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting is 1.0 mm (40 mils). These values help you configure the system correctly.
Troubleshooting and Common Issues
If you experience measurement problems, the extension cable is a possible source. Check for physical damage, loose connectors, or moisture ingress. The cable's DC resistance and capacitance values can be measured to verify integrity.
For example, a short or open in the cable will cause erratic readings. Use an ohmmeter to check the center conductor and shield resistance. Compare the readings to the specified values. If the cable is damaged, replace it with a new 330930-060-05-00.
Another common issue is incorrect cable length. Remember that the extension cable plus probe length must equal the Proximitor Sensor total length. If not, the system may not operate within its linear range.
