PR6423/000-031 + CON041 Sensor Module | Emerson EPRO Series

Product Description

Product Overview

The EPRO PR6423/000-031 + CON041 is an advanced eddy current vibration sensor module, designed for precise, non-contact measurement of shaft vibration, displacement, and eccentricity in critical industrial machinery.
This module combines the 8 mm PR6423/000-031 sensor with the CON041 signal converter, enabling accurate signal processing for condition monitoring and fault detection.

Moreover, the CON041 converts the weak signals from the eddy current sensor into standard voltage or current outputs (e.g., 0–10 V or 4–20 mA), ensuring compatibility with industrial control and monitoring systems.
The sensor’s 31 m integrated cable allows installation in large machines where the monitoring system is located at a significant distance. The rugged stainless steel housing and IP66 rating provide durability in harsh industrial environments.
