Overview

The EPRO PR6423/011-010 Eddy Current Displacement Sensor is an 11 mm non-contact probe designed for precise measurement of shaft vibration, axial displacement, and position in turbomachinery. As part of Emerson’s AMS machinery protection portfolio, it provides accurate and stable condition monitoring for turbines, compressors, pumps, and other high-value rotating equipment.

Moreover, its larger 11 mm probe diameter enhances mechanical rigidity, improving signal stability and measurement performance in heavy-duty and high-vibration environments. In addition, its rugged stainless-steel design and IP66 environmental protection ensure reliable operation under harsh industrial conditions, including high temperatures, moisture, and electromagnetic interference.
Therefore, the PR6423/011-010 is widely adopted in industries where machinery uptime, reliability, and predictive maintenance are mission-critical.
