Product Overview

The Bently Nevada 330130-085-13-CN is a 3300 XL Standard Extension Cable designed for use with the Bently Nevada 3300 XL 8 mm Proximity Transducer System.

It provides the electrical connection between the 3300 XL proximity probe and the Proximitor sensor, ensuring reliable transmission of vibration, displacement, and Keyphasor signals for continuous machinery condition monitoring and protection.

Featuring an 8.5-meter cable length, this model offers additional routing flexibility for large industrial installations. The “-CN” suffix identifies a specific configuration or regional ordering variant within the Bently Nevada product family. With a 0.876 kg shipping weight, this version features a reinforced cable construction suitable for demanding operating environments.

Technical Specifications

Function and Working Principle

The 330130-085-13-CN functions as a precision low-loss coaxial extension cable, transmitting analog signals from the proximity probe to the Proximitor sensor while maintaining high signal quality and minimizing attenuation.

Signal Transmission Process

1. The proximity probe detects shaft vibration or displacement using eddy-current sensing technology.
2. The probe converts mechanical movement into an analog electrical signal.
3. The extension cable transfers the signal with excellent shielding against electrical noise.
4. The Proximitor sensor conditions the signal for machinery monitoring, diagnostics, and protection systems.
