Product Overview

The Emerson Epro PR6424/010-010 CON021 is a high-performance 16mm eddy current displacement sensor designed for the non-contact measurement of critical machine parameters. This industrial-grade probe is a vital component for vibration monitoring and shaft positioning in heavy-duty rotating equipment. By generating an electromagnetic field at the probe tip, it detects micro-movements of the target surface—typically a turbine or compressor shaft—without physical contact, ensuring zero mechanical wear.

This sensor is specifically engineered to interface with the MMS6000 and MMS3000 machinery protection systems. It provides high-fidelity data on radial shaft vibration, axial position, and eccentricity. With its 16mm tip diameter, the PR6424 offers a larger measuring range and greater standoff distance than standard 8mm probes, making it the preferred choice for massive industrial rotors where significant displacement may occur.
