EPRO PR6423/001-030 Eddy Current Proximity Probe

The EPRO PR6423/001-030 is an eddy-current proximity probe designed for non-contact measurement of rotating machinery. Matched with the corresponding CON021 converter, it converts clearance variations between probe tip and metal shaft into continuous linear voltage signals to monitor shaft vibration and axial displacement.

This sensor adopts fully sealed stainless steel housing and shielded cable, capable of stable operation in high-temperature, oily and dusty bearing housings. It perfectly matches Emerson MMS3000 and MMS6000 monitoring systems and is widely used for turbomachinery maintenance and spare parts stocking in power and petrochemical industries.
