Product Overview

The Emerson PR6426/010-030 CON021/916-160 is a heavy-duty, non-contacting eddy current sensor engineered for critical machinery health monitoring. Part of the established EPRO product family, this 32mm tip-diameter transducer is specifically designed for measuring large-scale displacement and vibration in high-performance rotating assets. By generating an electromagnetic field at the sensor tip, it detects minute changes in distance between the probe and a metallic target without physical contact. This ensures zero wear and high-fidelity signal transmission even in legacy DCS environments. While officially discontinued by the manufacturer at the end of 2018, this robust module remains a vital spare part for ensuring the continued safety and operational uptime of turbine supervisory systems.

Critical Industrial Deployments

The PR6426/010-030 is essential for predictive maintenance and machine protection in the following sectors:

Power Generation: Monitoring the shaft eccentricity and axial position of large steam or gas turbines to prevent catastrophic internal friction.

Oil & Gas: Tracking the radial vibration of high-speed centrifugal compressors and heavy-duty pumping units.

Chemical Processing: Ensuring the mechanical integrity of agitators and large-scale motors where chemical vapor resistance is required.

Steel & Mining: Position sensing in high-impact rolling mills and heavy-duty conveyor systems.

Predictive Maintenance: Providing the necessary raw data for frequency analysis, allowing engineers to identify unbalance or misalignment before equipment failure occurs.
