Bently Nevada 330105-20-12-10-02-00 metric proximity sensor

Product Overview

The Bently Nevada 330105-20-12-10-02-00 is an 8mm metric proximity sensor engineered for high-precision shaft monitoring. As a core component of the 3300 XL series, it tracks radial vibration and axial thrust by measuring the gap between the tip and target. It provides the essential data needed for predictive maintenance on critical turbines, compressors, and pumps in demanding industrial environments.
