Epro PR6423/000-140-CN Eddy Current Shaft Vibration Probe System

Product Description

The PR6423/000-140-CN is an eddy-current based proximity probe engineered for continuous monitoring of shaft behavior in high-speed rotating equipment. It is commonly deployed in combination with CON021 signal conditioning modules to provide stable measurement of vibration, axial displacement, and rotor position in turbines, compressors, and industrial drive systems.

Built for demanding environments, the probe delivers non-contact measurement with high signal stability even under oil mist, high temperature, and mechanical vibration. Its extended 14-meter integrated cable design supports flexible installation in large-scale machinery layouts.
