Bently Nevada 330191-00-40-90-02-00 3300 XL 8 mm ETR Probe

Product Introduction

The Bently Nevada 330191-00-40-90-02-00 3300 XL 8 mm ETR Probe is a precision-engineered proximity probe designed for continuous, non-contact measurement of shaft vibration and displacement in critical rotating machinery. Belonging to the 3300 XL series, this probe is optimized for applications that demand long probe-to-monitor distances while maintaining exceptional linearity and signal stability. With a total length of 9.0 meters and an 8 mm tip diameter, it ensures accurate data acquisition in environments where equipment is subject to high temperatures, electrical noise, and mechanical stress. Its stainless-steel construction and advanced insulation make it ideal for use in power generation, petrochemical plants, and heavy industrial applications where reliability and accuracy are essential.
