Introduction
The Bently Nevada 330103-00-10-10-01-00 3300 XL 8mm Proximity Probe is a non-contact eddy current sensor designed for precise monitoring of shaft vibration, radial displacement, and axial position in rotating machinery. As part of the widely adopted 3300 XL proximity transducer system, it delivers stable, repeatable measurement performance in demanding industrial environments such as turbines, compressors, and large-scale pump systems.
The “-10-10” configuration typically indicates an extended housing and cable setup, making this probe suitable for installations where longer reach is required without compromising signal integrity or measurement accuracy.
