Technical Specification Report – 330851-02-000-026-50-01-05
1. Product Overview
The 330851-02-000-026-50-01-05 is a compact eddy current proximity probe assembly designed for high-precision, non-contact measurement of shaft vibration, axial displacement, and rotor movement in rotating machinery systems.
This configuration belongs to the NSv short-range probe family and is optimized for compact installation environments where stable signal output and high sensitivity are required. It is widely applied in continuous condition monitoring and machinery protection systems across industrial sectors.
The system operates by generating a high-frequency electromagnetic field at the probe tip. When the distance between the probe and a conductive metal surface changes, the resulting variation in eddy current response is converted into a proportional voltage signal.
