PR6423/000-120 Sensor Module | Emerson Industrial Vibration Monitoring

Product Description

Overview

The EPRO PR6423/000-120 is part of Emerson’s AMS / EPRO PR6423 series, providing non-contact measurement of shaft vibration, position, and eccentricity in industrial turbomachinery, including turbines, compressors, pumps, and gearboxes.

This sensor features an 8 mm probe tip and a 20 m integrated cable, ideal for installations where the monitoring system is located at a significant distance. Moreover, it uses eddy current technology, ensuring wear-free operation, high precision, and long-term stability under harsh conditions.

The PR6423 series integrates seamlessly with Emerson monitoring platforms such as AMS 6500 and VM600, and complies with API 670 standards for machinery protection.
