Introduction
The Bently Nevada 330103-05-16-10-02-00 3300 XL 8mm Proximity Probe is a high-precision, non-contact eddy current sensor designed for continuous monitoring of shaft vibration, radial displacement, and axial position in rotating machinery. As part of the 3300 XL proximity transducer system, it delivers stable and repeatable performance in harsh industrial environments such as turbines, compressors, pumps, and other mission-critical rotating equipment.
The “-16” configuration typically indicates an extended probe housing design, providing deeper mechanical reach and improved structural rigidity for installations where standard probe bodies are not sufficient. This makes it suitable for complex machinery layouts requiring long insertion depth and strong mounting stability.
