3. Product Overview

The 330101-39-47-10-02-05 is a high-temperature extended-barrel eddy current proximity probe belonging to Bently Nevada flagship 3300 XL series, the industry standard for critical rotating machinery protection.

It measures radial shaft vibration, axial thrust position, shaft eccentricity and Keyphasor rotational speed signal without touching the rotating metal shaft. The extra-long 4.7-inch unthreaded barrel is designed for deep bearing housing installation, solving installation space limitations on large steam turbines, centrifugal compressors, gas turbines and heavy-duty pumps in power plants, refineries and petrochemical facilities.
