Emerson PR6423/000-101-CN Eddy Current Sensor for Chinese Market

Product Description

Product Overview

The EPRO PR6423/000-101-CN 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 10 m integrated cable, ideal for medium-distance installations.
The CN suffix ensures compliance with China-specific certifications, enabling safe and reliable use in Chinese industrial environments.

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