Product Overview

The Bently Nevada 330104-02-15-10-01-00 is a 3300 XL 8 mm eddy-current proximity probe used for shaft vibration and radial displacement monitoring in rotating machinery.

It is part of the Bently Nevada 3300 XL proximity transducer system, widely used in turbines, compressors, pumps, and generators for continuous condition monitoring and machine protection.

This configuration supports a 1-meter system length, making it suitable for medium routing distances between the probe and signal conditioning equipment.

Technical Specifications

Function and Working Principle

The probe operates using the eddy-current principle, where electromagnetic induction is used to measure the distance between the probe tip and a conductive rotating shaft.

Operating Principle

1. Probe generates a high-frequency electromagnetic field
2. Eddy currents are induced in the shaft surface
3. Distance variation modifies signal response
4. Output voltage represents displacement and vibration

$x\propto V$

Where displacement (x) is proportional to the output voltage (V).

Key Functions
