Technical Specification Report – 330851-02-000-026-50-01-CN
1. Product Overview
The 330851-02-000-026-50-01-CN is a compact eddy current proximity probe assembly designed for high-precision, non-contact measurement of shaft vibration, axial displacement, and rotor dynamics in rotating machinery systems.
This configuration belongs to a short-range NSv probe variant with a China-specific configuration suffix, typically used for localized supply chain, documentation, or regional compliance variants while maintaining identical core sensing performance.
It is widely used in industrial condition monitoring systems where stable signal output, compact installation, and long-term measurement reliability are required.
The system works by generating a high-frequency electromagnetic field at the probe tip. Any change in distance between the probe and conductive metal target results in a proportional change in coil impedance, which is converted into a stable voltage signal.

6. Working Principle
The system operates based on eddy current induction:
- The probe generates a high-frequency electromagnetic field
- Conductive target surface induces eddy currents when distance changes
- Coil impedance varies proportionally with gap variation
- Signal conditioner converts this variation into calibrated voltage output
This allows precise non-contact measurement of micro-level shaft displacement and vibration.
