Technical Specification Report – 330851-01-000-070-10-01-00
1. Product Overview
The 330851-01-000-070-10-01-00 is a compact eddy current proximity probe assembly designed for high-accuracy, non-contact measurement of shaft vibration, axial displacement, and rotor movement in rotating machinery systems.
This configuration belongs to an extended NSv probe variant, optimized for stable signal output and reliable operation in compact industrial installations. It is commonly used in continuous machinery protection systems where precise shaft position tracking is required under harsh operating environments.
The system works by generating a high-frequency electromagnetic field at the probe tip. Any change in distance between the probe and a conductive metal target produces a proportional change in coil impedance, which is converted into a stable voltage signal for monitoring and diagnostics.
