Product Overview

The Emerson PR6423/010-010 CON021 is a high-precision eddy current displacement sensor engineered for the EPRO machinery protection series. This non-contact probe is designed for the high-resolution measurement of shaft vibration, axial thrust, and radial position in critical rotating machinery. By detecting minute variations in the electromagnetic field between the sensor tip and the target surface, the PR6423/010-010 provides the essential data required for condition monitoring and automated machinery protection.

Equipped with the CON021 specialized connector, this 8mm sensor is built to deliver high-linearity output even in the most strenuous industrial environments. It is a fundamental component for turbomachinery protection, allowing Distributed Control Systems (DCS) and asset management platforms to identify mechanical anomalies—such as bearing wear or shaft misalignment—long before they result in catastrophic failure.
