Emerson PR6423/010-010 Eddy Current Sensor for Machinery

Product Description

Product Overview

The Emerson EPRO PR6423/010-010 is a precision eddy current displacement sensor developed for continuous monitoring of rotating machinery.
This sensor belongs to the established PR6423 series, which is widely deployed in machinery protection and condition monitoring systems worldwide.

Moreover, the non-contact eddy current measurement principle eliminates mechanical wear and ensures long-term signal consistency.
Therefore, the sensor provides stable displacement and vibration data under high-speed and high-temperature operating conditions.

The PR6423/010-010 features an 8 mm probe tip combined with a 10 meter integrated cable, supporting flexible installation layouts.
In addition, its stainless steel construction enables operation in harsh industrial and offshore environments.
