Introduction
The Bently Nevada 330103-00-14-05-02-05 3300 XL 8mm Proximity Probe is a high-reliability eddy current proximity sensor designed for continuous monitoring of shaft vibration, radial displacement, and axial position in rotating machinery. As part of the trusted 3300 XL transducer system, it is built to deliver consistent, low-drift performance in demanding industrial environments such as turbines, compressors, and large-scale pump assemblies.
The “-14” configuration indicates an extended housing design, making this model suitable for installations requiring deeper mechanical reach or enhanced mounting stability in heavy-duty equipment layouts.
