PLCs, Power Supplies & Others

The EPRO PR6423/152-110 offers precision non-contact measurement for critical industrial machinery protection. As a key member of the proven PR 6400 series from EPRO, this 8mm eddy current sensor excels in monitoring axial position and radial vibration. Plant engineers rely on its stable data for protecting large turbines, compressors, and generators. Therefore, it forms a trustworthy foundation for predictive maintenance and condition monitoring programs.

Engineered for demanding environments, this sensor maintains excellent signal integrity despite temperature extremes and EMI. Moreover, it integrates directly with EPRO’s monitoring platforms like the MMS 6000 or MMS 3000 series. Consequently, users can build a complete and reliable protection framework for their most valuable rotating assets. Its performance is critical for preventing unplanned downtime in power generation and heavy industry.

Robust Design and Operational Principle

This sensor operates on the established eddy current principle for wear-free measurement. The probe tip generates a high-frequency electromagnetic field during operation. This field then induces circular currents in any nearby conductive target material. Subsequently, the connected monitoring system measures the change in the probe’s oscillation amplitude precisely. This change provides a linear voltage output that directly correlates to the physical distance.

Furthermore, its 3mm linear range offers greater installation flexibility than standard 2mm sensors. The robust, fully sealed housing contains a single sensing coil with no moving parts or internal energy storage. Additionally, the design draws all operating power directly from its compatible EPRO monitor. This ensures exceptional long-term signal stability and minimal drift for accurate trend analysis in critical machinery.
