Emerson PR6424/006-131 16mm Eddy-Current Contactless Sensor

Emerson PR6424/006-131 is a high-performance, 16mm eddy-current displacement sensor engineered for non-contact measurement of static and dynamic phenomena in critical rotating machinery. As part of the renowned PR642x series, this rugged sensor is specifically designed to deliver exceptional linearity, stability, and reliability in harsh industrial environments, making it a core component of condition monitoring systems like the Emerson CSI 6500 machinery health monitor.

Product Overview

Utilizing the eddy-current loss principle, the PR6424/006-131 generates a low-power radio frequency field to detect the position of a conductive target. Changes in the gap between the sensor tip and the target modulate the oscillator output, providing a direct, high-fidelity voltage signal proportional to displacement. This contactless method ensures zero mechanical loading and wear, enabling continuous, maintenance-free operation.
