Product Overview

The PR6426/000-121 CON031 is a high-integrity eddy current displacement sensor engineered by Emerson under the Epro product line. This non-contacting transducer is specifically designed for the critical measurement of shaft vibration and axial position in high-speed rotating machinery. By utilizing electromagnetic induction, the sensor provides millisecond-level feedback on shaft movement relative to the bearing housing. This data is fundamental for identifying mechanical irregularities such as rotor unbalance, shaft bow, or bearing wear. Its robust architecture is built to function within the harsh internal environments of turbines and compressors, where high pressure and oil immersion are common.
