Product Introduction
The Epro PR6423/015-111 sensor, combined with the CON041/SF converter, constitutes a high-precision, non-contact eddy current monitoring system developed for industrial-grade rotating machinery. Engineered by Emerson’s Epro division, this system is widely used for the real-time monitoring of shaft displacement, radial vibration, and axial positioning. The 8mm diameter probe is ideally suited for medium-range applications in turbines, compressors, and motors. The CON041/SF converter ensures reliable signal processing, making the system fully compliant with API 670 standards.
Whether for condition monitoring or machine protection, this sensor system delivers exceptional stability, resistance to environmental challenges, and integration flexibility with DCS and SCADA systems.
