PR6423/000-110 + CON021 Sensor Module | Emerson Industrial Solution

Product Description

Product Overview

The EPRO PR6423/000-110 + CON021 is a high-precision eddy current displacement sensor system from Emerson’s AMS / EPRO PR6423 series.
It provides non-contact measurement of shaft vibration, axial and radial displacement, and eccentricity in industrial turbomachinery such as turbines, compressors, pumps, and gearboxes.

This package combines the PR6423/000-110 sensor with the CON021 signal converter, enabling precise signal conditioning and compatibility with control systems using 0–10 V or 4–20 mA output signals.
The sensor features an 8 mm probe tip and a 10 m integrated cable, suitable for medium-distance installations.

Moreover, the system operates with wear-free eddy current technology, ensuring high precision, long-term stability, and reliable operation under harsh industrial conditions.
It integrates seamlessly with Emerson monitoring platforms, including AMS 6500 and VM600, while maintaining API 670 compliance for critical machinery protection.
