Product Overview

The PR6426/000-030 CON021 is a high-fidelity eddy current sensor engineered by Emerson for the AMS 6500 Classic System. This industrial-grade transducer is designed for non-contacting measurement of shaft vibration and displacement in critical rotating machinery. By detecting minute variations in electromagnetic fields, it provides precise analog feedback regarding the mechanical state of turbines and compressors. While the PR6426 series was officially discontinued by the manufacturer on December 31, 2018, this brand-new unit serves as a vital replacement part for maintaining legacy Distributed Control Systems (DCS). Its high-frequency response and signal stability make it indispensable for early-stage fault diagnosis and machinery protection.

Comprehensive Hardware Attributes and Specifications

The PR6426/000-030 CON021 is built to provide linear measurement accuracy even in thermally unstable and high-pressure environments. Its robust casing protects the internal induction coils from industrial contaminants.
