PR6423/010-000 | Epro | Non-Contact Eddy Current Transducer

Overview

The Epro PR6423/010-000 is a non-contact Eddy Current Transducer designed for accurate measurement of static and dynamic shaft displacement. It is ideal for monitoring shaft eccentricity, vibration, and displacement in industrial machinery, adhering to international standards such as DIN 45670, ISO 10817-1, and API 670. The sensor is rated for explosive areas with Eex ib IIC T6/T4.
