Bently Nevada 330930-065-01-05 3300 NSv Extension Cable

The Bently Nevada 330930-065-01-05 is a 6.5 metres 3300 NSv (Narrow Signal Voltage) Extension Cable designed for use with Bently Nevada’s proximity transducer systems. This cable plays a critical role in extending the distance between the proximity probe and the Proximitor sensor without compromising signal integrity or system calibration.

As part of the 3300 NSv series, this extension cable is engineered for compact machinery applications where probe mounting space is limited and system reliability is paramount. It delivers low-noise signal transmission and is fully compatible with other NSv system components, ensuring factory-matched performance.

Built to withstand harsh industrial conditions, this extension cable features ruggedized connectors and materials suited for continuous operation in high-vibration, high-temperature environments such as turbines, compressors, and gearboxes.

Technical Specifications

Applications

The 330930-065-01-05 Extension Cable is used in conjunction with 3300 NSv proximity transducers to monitor the radial or axial shaft position in compact and small-scale rotating machinery. It’s widely implemented in the following application areas:

• Steam and Gas Turbines – vibration and axial position monitoring

• Centrifugal Compressors – high-speed shaft displacement tracking

• Industrial Pumps – small-frame pump position and vibration diagnostics

• Gearboxes and Motors – condition monitoring in compact assemblies

• Aerospace Test Rigs – fine-resolution vibration testing on miniature components

• Hydraulic Machines – accurate monitoring where space constraints exist

The cable’s extended length and signal integrity are essential for systems where the Proximitor sensor must be installed far from the probe due to temperature or physical space restrictions.

Frequently Asked Questions (FAQ)

1. What is the purpose of the 330930-065-01-05 extension cable?

It extends the distance between the NSv proximity probe and the Proximitor sensor while maintaining signal fidelity.

2. Can this cable be used with standard 3300 XL probes?

No. It is specifically designed for 3300 NSv systems, which have different electrical characteristics.

3. What is the difference between NSv and XL systems?

NSv (Narrow Signal Voltage) systems are tailored for compact machinery with shorter target distances and smaller probe sizes.

4. Is the cable factory matched?

Yes. The extension cable is factory-matched with NSv probes and sensors to ensure accuracy without field calibration.

5. What materials are used in the cable jacket and insulation?

The jacket is FEP (for chemical resistance), and insulation is made of PFA for high-temperature durability.

6. Can the cable be field-trimmed or shortened?

No. The cable length must not be modified as it would invalidate factory matching and affect system performance.

7. Does it support harsh industrial environments?

Yes. It is built to withstand chemicals, vibration, oil exposure, and high temperatures.

8. What temperature can it operate at?

The cable can operate reliably from -51°C to +177°C.

9. Is the cable shielded against electromagnetic interference (EMI)?

Yes. It features both braided and foil shielding for maximum EMI suppression.

10. How is this cable different from a standard coaxial cable?

It is a triaxial design with specialized impedance, shielding, and connector configurations specific to NSv systems.
