Introduction — Stable Measurement Performance for Industrial Rotating Machinery
The Bently Nevada 330103-00-04-20-02-00 3300 XL 8 mm Proximity Probe is a precision eddy current sensor designed for continuous monitoring of shaft vibration, displacement, and position in critical rotating equipment. As part of the established 3300 XL proximity transducer system, it provides reliable signal stability, high linear accuracy, and long-term durability in harsh industrial environments.
The “20” configuration segment typically corresponds to a 2.0 m cable length option, making this model suitable for installations requiring extended routing between the probe and Proximitor® sensor while maintaining signal integrity and measurement accuracy across industrial systems.
