Epro PR6423/10R-030+CON021 8mm Eddy Current Sensor

The Epro PR6423/10R-030+CON021 is a precision-engineered eddy current proximity sensor system, designed to deliver reliable non-contact measurements of shaft displacement, vibration, and position. Manufactured by Epro (part of Brüel & Kjær Vibro), this sensor system is widely used in condition monitoring and machinery protection systems, particularly in high-value rotating equipment.

This model combines the PR6423/10R-030 probe—featuring a rugged 8 mm tip and radial cable exit—with the CON021 converter, forming a complete transducer system optimized for use in harsh industrial environments such as power generation, oil and gas, petrochemical, and heavy machinery sectors.
