Products Overview
PR6426/010-010 is an original EPRO (Emerson) eddy current sensor, combined with CON021 preamplifier to form a complete set of systems for rotating machinery shaft vibration / shaft displacement monitoring. It is specially designed for online monitoring of key equipment such as steam turbines, gas turbines, fans, compressors, etc. The product adopts a non-contact eddy current measurement principle, which can accurately collect key parameters such as shaft displacement, vibration, eccentricity, and rotational speed, meeting the API 670 international standard. It is widely used in equipment protection and condition monitoring in industrial fields such as power plants, petrochemicals, and metallurgy.
