Introduction
The Bently Nevada 330901-00-16-05-02-05 3300 NSv Proximity Probe is a precision eddy-current displacement sensor engineered for vibration and shaft position monitoring in rotating machinery. As part of the 3300 NSv (Narrow Side-View) transducer system, it is specifically designed for compact mechanical installations where standard probe geometries cannot fit, while still delivering highly stable and repeatable measurement performance.
This probe is widely used in turbines, compressors, pumps, and other critical rotating assets across power generation and heavy industrial environments. It supports early fault detection strategies by continuously monitoring shaft vibration and position with high accuracy and long-term stability.
