Product Introduction
The Bently Nevada 330909-00-20-10-02-05 3300 NSv Proximity Probe is a high-performance eddy current sensor engineered for accurate, non-contact measurement of shaft vibration and radial displacement in compact or restricted installations. Part of the 3300 NSv (Narrow Side-view) series, it is specifically designed for equipment where traditional 8 mm probes are too large. Its rugged stainless-steel construction, excellent linearity, and wide operating temperature range make it ideal for demanding industrial environments such as power generation, petrochemical processing, and heavy rotating machinery.
