Bently Nevada 330904-00-25-05-02-05 3300 NSv Proximity Probes

Product Introduction

The Bently Nevada 330904-00-25-05-02-05 3300 NSv Proximity Probe is a high-precision non-contact displacement and vibration sensor designed for continuous monitoring of critical rotating machinery. Using eddy current technology, it measures shaft position and dynamic vibration with exceptional accuracy. Its compact 0.5 m length and rugged stainless-steel construction make it ideal for harsh industrial environments such as power generation, oil & gas, and heavy manufacturing. The probe’s design supports predictive maintenance strategies by detecting early signs of misalignment, imbalance, or bearing wear, helping operators prevent costly unplanned shutdowns.
