Product Overview

The Bently Nevada 330908-00-46-05-02-05 is a 3300 NSv eddy-current proximity probe engineered for non-contact measurement of shaft relative displacement in machinery protection and condition monitoring systems. The NSv probe format is typically applied where installation space is limited and where smaller target areas or side-view constraints can affect measurement quality. When installed with the correct NSv extension cable and matching Proximitor sensor, the probe delivers a stable proportional output used to monitor vibration (dynamic) and position (static) on critical rotating assets.

For modernization projects replacing older proximity transducer families, NSv solutions are implemented as a complete channel upgrade. In practice, the probe, extension cable, and Proximitor sensor are replaced together to maintain calibration integrity, achieve the intended scale factor, and ensure compatibility with the connected monitoring system.

Key Technical Characteristics

Implementation notes

• Must be paired with NSv-compatible extension cable and Proximitor sensor to achieve specified scaling and linearity

• Shorter linear span than standard 5 mm and 8 mm proximity systems, but optimized for tight clearances and smaller targets

• Performance depends on target material, probe gap setting, mounting geometry, and correct total system length

Industrial Applications

• Shaft vibration and displacement monitoring on turbines, compressors, pumps, motors, and gear-driven trains where probe space is limited

• Upgrades from legacy transducer channels when moving to NSv proximity architecture (probe + cable + Proximitor as a matched set)

• Small-target or side-view measurement locations inside bearing housings and machine casings

• Continuous protection inputs to TSI and rack-based monitoring systems for critical rotating machinery
