Epro CON021+PR6423/00R-010 Eddy Current Sensor System

Product Description

The CON021 + PR6423/00R-010 system by Emerson EPRO is a precision-engineered solution for non-contact shaft measurement in rotating equipment. It combines a signal conditioning unit with a high-resolution eddy current probe to deliver reliable displacement and vibration data for machinery diagnostics and protection.

This configuration is typically deployed in critical assets where continuous monitoring of shaft behavior is required to prevent failures and optimize maintenance planning. The converter processes low-level probe signals into stable analog outputs suitable for integration with control and monitoring systems.

FAQ

Q: What parameters can this system monitor?
A: It measures shaft displacement, vibration amplitude, position, and eccentricity in rotating machinery.

Q: Can other probes be used with the CON021 converter?
A: Yes, it supports multiple PR642x series probes, though performance depends on correct configuration.

Q: Is the system suitable for harsh environments?
A: The probe can be used in demanding conditions, but the converter should be mounted in a protected enclosure due to its IP20 rating.
