PR6423/000-041 | Emerson EPRO Turbomachinery Monitoring Sensor

Product Description

Product Overview

The EPRO PR6423/000-041 is a high-precision eddy current displacement sensor from Emerson’s AMS / EPRO PR6423 series.
It provides non-contact measurement of shaft vibration, radial and axial displacement, and eccentricity in industrial turbomachinery such as turbines, compressors, pumps, and gearboxes.

This model features an 8 mm probe tip with a 41 m integrated cable, suitable for installations requiring long-distance connection to monitoring systems.
It uses eddy current technology to ensure wear-free operation, high accuracy, and long-term stability in demanding industrial environments.

Moreover, the PR6423 series is fully compatible with Emerson monitoring platforms including AMS 6500 and VM600, while maintaining API 670 compliance for critical machinery protection.
