Product Overview

The Bently Nevada 330130-085-03-00 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, ensuring accurate transmission of vibration, displacement, and Keyphasor signals for rotating machinery monitoring and protection.

With an 8.5-meter cable length, this version supports longer routing distances, while the “-03-00” configuration typically indicates a heavier-duty construction variant within the product family.

Technical Specifications

Function and Working Principle

The 330130-085-03-00 functions as a low-loss coaxial signal 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 movement 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.
