Product Introduction
The PR6423/000-000 6140-00031 EPRO is a specialized proximity probe designed for the demanding environments of steam turbines, gas turbines, and high-speed centrifugal compressors. As a senior engineer who has overseen countless turbine protection upgrades, I recognize this unit as a fundamental component for identifying shaft instability before it results in catastrophic machine failure.
Operating on the eddy current principle, this sensor creates a high-frequency electromagnetic field that interacts with the target shaft. The PR6423/000-000 6140-00031 EPRO translates the physical gap between the 8 mm tip and the ferromagnetic surface into a measurable electrical signal. This specific part number, 6140-00031, indicates a baseline configuration intended for integration with Emerson’s CON series signal converters, ensuring the 8 V/mm sensitivity required by API 670 standards.
