Product Overview

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

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

With an 8.5-meter cable length, this version is designed for installations requiring slightly extended routing while maintaining stable signal integrity. The “-CN” suffix indicates a specific configuration or regional variant within the Bently Nevada product coding system.

Technical Specifications

Function and Working Principle

The 330130-085-02-CN functions as a low-loss coaxial signal transmission cable, carrying analog signals from the proximity probe to the Proximitor sensor while preserving accuracy over an extended distance.

Signal Flow

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