Product Introduction
The Epro PR6423/012-010 + CON021 is a high-precision, non-contact eddy current sensor system designed for monitoring the dynamic behavior of rotating machinery. Featuring an 8mm probe diameter and a 10mm shaft length, this sensor is ideal for installations where space is limited but accurate displacement measurements are critical. Paired with the CON021 converter, the system provides a linear voltage output proportional to the measured displacement, enabling real-time diagnostics of shaft vibration, position, and eccentricity.
