Epro CON021+PR6423/01M-010 Eddy Current Sensor Displacement System

Product Description

The PR6423/01M-010 paired with CON021 forms a precision eddy current measurement system developed by EPRO for continuous monitoring of shaft dynamics in rotating machinery. It is widely applied in vibration analysis and axial/radial displacement tracking where non-contact measurement stability is critical.

The system consists of a high-temperature resistant proximity probe and a signal conditioning converter, enabling accurate linear output proportional to target surface movement. It is engineered for harsh mechanical environments where oil contamination, vibration, and thermal stress are present.
