Product Overview

The Bently Nevada 330130-085-00-02 is a 3300 XL Standard Extension Cable used in the Bently Nevada 3300 XL proximity transducer system.

It provides the electrical connection between the 3300 XL proximity probe and the Proximitor sensor, enabling accurate transmission of vibration, displacement, and Keyphasor signals used in machinery condition monitoring and protection systems.

With an 8.5-meter cable length, this model supports slightly longer routing distances than standard 8-meter variants, offering additional installation flexibility in large industrial equipment layouts.

Technical Specifications

Function and Working Principle

The 330130-085-00-02 functions as a low-loss coaxial signal transmission cable, carrying the analog signal generated by the proximity probe to the Proximitor sensor while preserving signal integrity over an extended distance.

Signal Flow

1. The proximity probe detects shaft motion using eddy-current technology.
2. Mechanical displacement is converted into an analog electrical signal.
3. The extension cable transmits the signal to the Proximitor sensor.
4. The Proximitor sensor conditions the signal for monitoring, diagnostics, and protection systems.
