Product Introduction
The Epro PR6423/000-031+CON041-CN is a high-performance eddy current displacement sensor designed specifically for critical machine condition monitoring applications. Engineered by Epro (now part of Brüel & Kjær Vibro), this proximity probe system offers non-contact measurement of shaft displacement, eccentricity, axial thrust position, and vibration.
This specific model features a sensing tip diameter of 8 mm, making it well-suited for compact installation spaces and standard mounting conditions. The CON041-CN converter is pre-configured and calibrated to work precisely with the sensor and extension cable, ensuring high measurement accuracy and reliability across a wide range of industrial environments.
The PR6423 series is widely used in power plants, refineries, chemical plants, and rotating equipment applications, particularly for condition monitoring and machinery protection systems.
