Product Description
Overview
The Emerson CON021 signal converter paired with the PR6423/000-031-CN eddy current probe forms a high-precision monitoring solution for critical rotating machinery. Designed for integration with advanced systems such as MMS6000 and AMS 6500, this measurement chain accurately tracks radial shaft vibration, displacement, and static shaft position in turbines, compressors, pumps, and industrial fans.
This system uses non-contact eddy current technology, combining mechanical robustness and electronic precision to deliver reliable performance in demanding industrial environments.
Components
PR6423/000-031-CN Probe
The probe features an 8.0 mm tip diameter and is optimized for industrial deployment with:
