EPRO PR6423/003-130 | High-Precision 8 mm Eddy Current Displacement Sensor
The EPRO PR6423/003-130 is a high-sensitivity, non-contact eddy current displacement sensor designed by Emerson (EPRO) for precise measurement of shaft vibration, radial displacement, and position in rotating machinery. It is engineered to provide reliable, repeatable data for machinery protection and predictive maintenance systems such as MMS 6000 and AMS 6500.
This sensor is ideal for steam turbines, gas turbines, compressors, pumps, and fans. Its compact 8 mm diameter and robust construction ensure accurate readings in harsh industrial environments. Pairing the PR6423/003-130 with a CON021 signal converter allows for standardized voltage or current output for seamless integration into monitoring and control systems.
