Product Overview
The Bently Nevada 330104-00-22-10-02-05 3300 XL 8 mm Proximity Probe is an industry-leading sensor designed to measure shaft vibration, relative position, and axial thrust in critical rotating machinery. Utilizing proven eddy current sensing technology, this probe forms part of the globally trusted 3300 XL series and delivers highly accurate, stable, and linear output signals, even under extreme operating conditions.
This particular configuration features a 1 meter probe cable length, non-armored construction, and an 8 mm probe tip, making it an ideal solution for applications requiring flexibility and excellent measurement performance.
Compatible with 3300 XL Proximitor Sensors and extension cables, the probe provides a consistent voltage output corresponding to shaft displacement. It is a vital component in machine protection and condition monitoring systems across industries like oil & gas, power generation, refining, chemicals, and heavy manufacturing.
