Description
Overview
The Bently Nevada 330930‑065‑00‑00 extension cable is part of the 3300 NSv (Narrow Side‑view) proximity transducer family, engineered for machinery where standard 5 mm or 8 mm probe systems cannot be installed due to counter‑bore, side‑view, or restricted mounting geometries. Its compact design and stable electrical characteristics make it suitable for modern high‑density compressor layouts and other confined‑space applications.
Functional Characteristics
This extension cable is designed to operate as a key component of the 3300 NSv Proximity Transducer System. When paired with the appropriate NSv probe and Proximitor sensor, the cable supports accurate radial vibration measurement on shafts below 51 mm and axial position measurement on flat targets under 15 mm. Its performance is optimized for centrifugal air compressors, process gas compressors, and refrigeration compressors.
The 330930‑065‑00‑00 maintains mechanical and electrical interchangeability with legacy systems such as the 3000‑Series, 7000‑Series 190 Transducer Systems, and 3300 RAM systems. Enhanced chemical resistance and improved side‑view performance ensure long‑term reliability in harsh industrial environments.

FAQ
Q: Can this cable be used with standard 3300 XL probes? A: No. The NSv system uses different electrical characteristics and must be paired with NSv probes and NSv Proximitor sensors.
Q: Is the cable pre‑calibrated? A: Yes. It is factory‑calibrated to an AISI 4140 steel target to ensure measurement accuracy.
Q: What applications benefit most from the NSv system? A: Machinery with limited installation space, especially compressors with counter‑bore or side‑view restrictions.
