Introduction — Precision Stability for High-Critical Rotating Assets
The Bently Nevada 330103-00-13-10-02-05 3300 XL 8mm Proximity Probe is a high-performance eddy-current sensor designed for continuous monitoring of shaft vibration and displacement in rotating machinery. As part of the widely adopted 3300 XL 8mm proximity transducer system, it delivers reliable, drift-resistant measurement performance in demanding industrial environments such as turbines, compressors, pumps, and generators.
The “13” configuration typically corresponds to an extended mechanical case variant, offering additional installation flexibility for deeper mounting requirements while maintaining the same proven measurement integrity of the 3300 XL platform.
