Emerson PR6423/000-030 + CON021 | Shaft Vibration Eddy Current Module

Product Description

Product Overview

The EMERSON EPRO PR6423/000-030 + CON021 is an advanced eddy current sensor module designed for precise, non-contact measurement of shaft vibration, position, and eccentricity in critical industrial machinery.
This system combines the 8 mm PR6423/000-030-CN sensor with the CON021 signal converter, enabling accurate monitoring and data acquisition for turbomachinery.

Moreover, the CON021 signal converter processes the weak electrical signals from the eddy current sensor and outputs a standard voltage signal (0–10 V or 4–20 mA), ensuring seamless integration with industrial control systems.
The sensor’s compact design allows installation in tight spaces, while the combination provides reliable, long-term performance for condition monitoring and fault detection.
