Technical Specification Report – 330851-01-000-020-10-00-05
1. Product Overview
The 330851-01-000-020-10-00-05 is a high-performance eddy current proximity probe assembly designed for precise, non-contact measurement of shaft vibration, axial position, and rotor displacement in rotating machinery.
It is typically used in industrial machinery protection systems where continuous monitoring of shaft movement is required to ensure stable operation and early fault detection.
The system operates by generating an electromagnetic field between the probe tip and a conductive metal target surface, converting distance variation into a proportional electrical signal for downstream monitoring and analysis.
