Bently Nevada 330730-080-00-00 3300 XL 11 mm Extension Cable

Overview

The Bently Nevada 330730-080-00-00 is a precision 3300 XL 11 mm extension cable for proximity transducer systems.
It reliably transmits low-noise vibration and displacement signals between probes and Proximitor® sensors in critical machinery.
Moreover, the 8.0-meter length supports flexible installations across turbines, compressors, pumps, and other rotating assets.
Engineers trust this cable because it maintains signal integrity under high temperatures, vibration, and aggressive industrial chemicals.

Functional Highlights / Key Benefits

Accurate signal transmission supports dependable machinery protection and condition monitoring in continuous-duty environments.
In addition, FEP insulation and dense shielding minimize electromagnetic interference and long-term signal degradation.
The cable design ensures stable impedance characteristics, therefore improving measurement repeatability across the monitoring system.
For instance, harsh oil and gas sites benefit from its chemical resistance and high thermal stability.
