PR6423/000-001 | Emerson EPRO Shaft Displacement Sensor

Product Description

Product Overview

The Emerson EPRO PR6423/000-001 is a high-precision eddy current displacement sensor designed for continuous condition monitoring of rotating machinery.
This sensor belongs to the proven EPRO PR6423 series, which is widely trusted in critical turbomachinery protection systems worldwide.

Moreover, the non-contact measurement principle eliminates mechanical wear and ensures long-term signal stability.
Therefore, the sensor delivers reliable displacement data even under high speed, high temperature, and vibration-intensive operating conditions.

The PR6423/000-001 features an 8 mm probe tip, making it suitable for radial and axial shaft displacement measurements.
In addition, its rugged stainless steel construction supports harsh industrial and offshore environments.
