Bently Nevada 330930-040-00-05 3300 NSv Extension Cable

Bently Nevada 330930-040-00-05 3300 NSv Extension Cable

The Bently Nevada 330930-040-00-05, also cataloged as the 3300 NSv Extension Cable, operates as a dedicated hardware component for eddy-current signal transmission within Bently Nevada 3300 XL NSv Proximity Transducer System platforms.

Hardware Specifications

Cross-Talk Suppression and Signal Transmission Characteristics

The 3300 NSv Extension Cable is a component of the 3300 XL NSv Proximity Transducer System, providing the electrical connection between the 3300 NSv probe and 3300 XL NSv Proximitor Sensor. The cable maintains the signal path required for eddy-current displacement measurement systems used for shaft vibration and position monitoring.

The 330930-040-00-05 configuration provides a 4.0 meter (13.1 feet) cable length arrangement with defined electrical characteristics, including 50 ohm output resistance and typical cable capacitance of 69.9 pF/m (21.3 pF/ft). These characteristics support proper operation of the complete proximity transducer chain.

The cable configuration is intended for restricted mechanical installation environments where the 3300 XL NSv system is applied, including applications involving compact compressor assemblies and machines with limited probe access.

Rotor Dynamics Signal Chain Integration

The extension cable supports signal transmission for measurements including radial vibration, radial position, axial thrust position, tachometer, zero speed, and Keyphasor phase reference signals when installed with compatible NSv probe and Proximitor Sensor components.

The 3300 XL NSv architecture uses matched probe, extension cable, and Proximitor Sensor combinations to maintain measurement performance. Proper cable installation practices support stable electrical characteristics across the complete eddy-current measurement loop.

Field Installation Guidelines

Install the extension cable with appropriate mechanical support to prevent excessive stress on connectors and cable entry points. Maintain separation from high-current power wiring and switching circuits to reduce electrical interference.

Avoid sharp bending, crushing, and mechanical tension during cable routing. Maintain the cable shielding and grounding arrangement according to the vibration monitoring system installation requirements.

Verify connector compatibility between the extension cable, NSv probe, and Proximitor Sensor before commissioning. Confirm the complete transducer chain configuration before applying machine monitoring signals.
