Product Overview

The Bently Nevada 330130-085-02-00 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 reliable transmission of vibration, displacement, and Keyphasor signals used in rotating machinery monitoring and protection systems.

With an 8.5-meter cable length, this model is designed for installations requiring slightly extended routing while maintaining stable signal integrity and system calibration.

Technical Specifications

Function and Working Principle

The 330130-085-02-00 functions as a low-loss coaxial transmission cable, carrying analog signals from the proximity probe to the Proximitor sensor while preserving measurement accuracy over extended distance.

Signal Flow

1. The proximity probe detects shaft vibration using eddy-current sensing.
2. Mechanical motion 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.
