Epro CON031/916-240+PR6426/010-141 Shaft Vibration Monitoring System

Product Overview

The CON031/916-240 + PR6426/010-141 is an integrated shaft vibration measurement solution from Epro (Emerson), combining a signal conversion unit with a high-resolution eddy current probe. This configuration is engineered for continuous monitoring of shaft movement and vibration in critical rotating machinery.

By pairing a dedicated converter with a precision sensor, the system delivers stable, real-time measurement data suitable for machinery protection and condition-based maintenance strategies.

System Configuration

This assembly consists of two coordinated components:

• CON031/916-240 signal converter module

• PR6426/010-141 eddy current displacement sensor

The converter processes raw probe signals and outputs standardized industrial signals, while the sensor performs non-contact measurement of shaft displacement.
