Bently Nevada 330104-00-22-10-01-05 Proximity Probe

Product Overview

The Bently Nevada 330104-00-22-10-01-05 is a high-precision, non-contacting transducer designed for critical machinery protection. As a core component of the 3300 XL series, it delivers accurate vibration and displacement data for turbines, compressors, and motors. This probe ensures reliable monitoring in harsh industrial environments by providing a linear voltage output proportional to the shaft distance, facilitating effective predictive maintenance and preventing catastrophic equipment failure.
