Product Overview

The Emerson PR6423-005-001 is a specialized non-contacting eddy current displacement sensor engineered for the precise measurement of shaft vibration and position within rotating machinery. As a critical component of the EPRO product line, this 8mm probe converts the distance between the sensor tip and the conductive target into a proportional voltage signal. This transducer is specifically designed for integration with machinery protection systems, ensuring the mechanical integrity of high-speed industrial assets by providing continuous data on shaft speed and displacement.

Primary Field Applications

This displacement transducer is an essential diagnostic tool for heavy-duty rotating equipment. It is frequently installed in steam and gas turbines, centrifugal compressors, and large industrial pumps to monitor radial shaft vibration and axial thrust position.

By detecting the passage of a keyway or gear tooth, the PR6423-005-001 serves as a highly accurate speed probe, feeding critical timing information into Distributed Control Systems (DCS). Its resilience against electromagnetic interference and chemical exposure makes it the preferred choice for monitoring critical machinery in power generation facilities, petrochemical refineries, and large-scale manufacturing plants where downtime prevention is a primary operational objective.
