Product Overview

The Bently Nevada 330130-085-13-RU 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, ensuring accurate transmission of vibration, displacement, and Keyphasor signals for machinery condition monitoring and protection applications.

With an 8.5-meter cable length, this model is suitable for large-scale industrial installations requiring extended routing and robust mechanical performance. The “-RU” suffix indicates a specific configuration or regional variant within the Bently Nevada ordering system. Its 0.876 kg weight reflects a reinforced, heavy-duty construction.

Technical Specifications

Function and Working Principle

The 330130-085-13-RU operates as a low-loss coaxial signal transmission cable, carrying analog signals from the proximity probe to the Proximitor sensor while preserving measurement accuracy over long distances and harsh environments.

Signal Flow

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