Technical Specification Report – 330851-01-000-030-50-01-00
1. Product Overview
The 330851-01-000-030-50-01-00 is a compact eddy current proximity probe assembly designed for precise, non-contact measurement of shaft vibration, axial displacement, and rotor movement in rotating machinery systems.
It is optimized for small-shaft applications where installation space is limited but measurement accuracy and long-term stability are critical for continuous condition monitoring.
The system operates by generating a high-frequency electromagnetic field at the probe tip. Variations in the distance between the probe and a conductive target surface are converted into proportional electrical signals, enabling real-time displacement and vibration analysis.

6. Working Principle
The system operates based on eddy current induction:

- The signal conditioner converts this variation into calibrated voltage output
This allows precise non-contact measurement of micro-level shaft movement in rotating machinery.
