Product Description
The Bently Nevada 330101-20-45-05-02-05 is a high-performance 3300 XL 8 mm Proximity Probe designed for vibration and position measurement in rotating machinery. It outputs a voltage proportional to the distance between the probe tip and the target surface. Optimized for fluid-film bearing machines, it offers robust construction, superior RFI immunity, and full compliance with API 670 standards.
