Product Overview

The Bently Nevada 330130-085-03-RU is a 3300 XL Standard Extension Cable used in the Bently Nevada 3300 XL proximity transducer system.

It connects the 3300 XL proximity probe to the Proximitor sensor, enabling accurate transmission of vibration, displacement, and Keyphasor signals for machinery condition monitoring and protection applications.

With an 8.5-meter cable length, this version is suitable for large industrial installations requiring extended routing and robust mechanical construction. The “-RU” suffix indicates a specific configuration or regional variant within the Bently Nevada product coding system.

Technical Specifications

Function and Working Principle

The 330130-085-03-RU functions as a low-loss coaxial signal transmission cable, carrying analog signals from the proximity probe to the Proximitor sensor while maintaining high accuracy and noise immunity over extended distance.

Signal Flow

1. The proximity probe detects shaft vibration using eddy-current sensing.
2. Mechanical movement 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 and protection systems.
