Technical Specification Report – 330851-02-000-026-10-00-00
1. Product Overview
The 330851-02-000-026-10-00-00 is a compact eddy current proximity probe designed for precise, non-contact measurement of shaft vibration, axial displacement, and rotor dynamics in rotating machinery.
This configuration belongs to a short-range NSv probe variant, optimized for compact mechanical installations where high measurement sensitivity and stable signal output are required. It is commonly used in machinery protection and condition monitoring systems operating in continuous industrial environments.
The system operates by generating a high-frequency electromagnetic field at the probe tip. Changes in the gap between the probe and a conductive target surface are converted into proportional voltage signals, enabling accurate displacement and vibration measurement.
