Technical Functionality and Measurement Principle
The Bently Nevada 330104-00-10-05-02-05 is a high-precision eddy current sensor designed for non-contacting displacement measurements in rotating machinery. By establishing an electromagnetic field, the probe tracks the gap between the sensor tip and the observed metal target. This allows for the simultaneous capture of static data, such as shaft position and thermal expansion, and dynamic data, including radial vibration and phase reference (Keyphasor) signals.
Specific Model Configuration

Industrial Application Areas
- Radial Vibration: Monitoring shaft motion within fluid-film bearings.
- Thrust Position: Detecting axial movement to prevent catastrophic rotor-to-stator contact.
- Differential Expansion: Tracking the relative growth between the machine rotor and casing.
- Keyphasor Timing: Providing a once-per-turn reference signal for speed measurement and vector analysis.
