Product Overview

The Bently Nevada 330130-080-12-RU is a 3300 XL Standard Extension Cable used within the Bently Nevada 3300 XL proximity transducer system.

It provides the critical signal 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-meter cable length, this model is suitable for industrial installations requiring extended routing while maintaining stable signal integrity. The “-RU” suffix denotes a specific configuration or regional ordering variant within the product coding system.

Technical Specifications

Function and Working Principle

The 330130-080-12-RU functions as a low-loss coaxial signal transmission cable, carrying analog signals generated by the proximity probe to the Proximitor sensor with minimal attenuation and interference.

Signal Flow

1. The proximity probe detects shaft vibration using eddy-current technology.
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.
