Product Overview
The Bently Nevada 330101-00-08-20-02-CN 3300 XL 8 mm Proximity Probe is a precision non-contact vibration and displacement sensor designed for industrial rotating machinery monitoring. As a member of the advanced 3300 XL proximity transducer system, this probe delivers stable, high-accuracy measurements for shaft vibration, position, and dynamic displacement.
Engineered with an 8 mm sensing tip and robust stainless-steel housing, the probe uses eddy-current sensing technology to detect small changes in the distance between the probe tip and conductive targets. This capability allows maintenance teams to continuously monitor turbines, compressors, generators, and pumps, enabling early detection of mechanical issues and improved machinery protection strategies.
