Bently Nevada 330930-065-04-CN 3300 NSv Extension Cable

Product Overview

330930-065-04-CN is a Bently Nevada 3300 NSv extension cable designed for signal transmission within compact proximity transducer systems used in turbines, compressors, pumps, and other rotating machinery. This extension cable supports industrial applications in refineries, power plants, and petrochemical facilities where reliable vibration and shaft position monitoring is essential. The stainless steel armored construction with FEP jacket improves resistance against abrasion, oil exposure, moisture, and chemical contamination. Connector protectors enhance long term connection stability under vibration conditions. Engineers use this cable to maintain signal integrity between NSv probes and proximitor sensors, reducing measurement errors and preventing unexpected machinery downtime in hazardous operating environments.

Suffix Breakdown

The model code defines cable configuration and hazardous area compliance:

• 065 = Cable length 6.5 metres

• 04 = Stainless steel armored cable with FEP jacket and connector protectors

• CN = China-specific hazardous area approvals including NEPSI, CCC, and ATEX IECEx compliance

This configuration ensures compatibility with harsh industrial installations and hazardous area requirements.
