Bently Nevada 330930-045-00-CN NSv Extension Cable

Overview

The Bently Nevada 330930-045-00-CN is a high-reliability 3300 NSv Extension Cable engineered for demanding vibration and position monitoring applications. It forms a critical part of the 3300 NSv Proximity Transducer System, which also includes the probe and Proximitor sensor. The cable ensures precise signal integrity between the probe and the monitoring hardware, even in harsh industrial environments. Moreover, its 4.5-meter length gives engineers flexible routing options for compact or restricted installations.

This model is manufactured in the USA and supplied as a CN-approved variant, making it compliant for China-market requirements. The cable delivers stable performance across extreme temperatures, therefore supporting long-term reliability in turbines, compressors, pumps, and other rotating machinery.
