Overview of CON021

The EPRO CON021 is a precision signal converter developed by Emerson (formerly EPRO) for use with the PR642x series non-contact eddy current sensors. It converts the raw analog signals from the probes into standardized output signals (such as 4–20 mA or 0–10 V DC), allowing for seamless integration with control systems, protection relays, and condition monitoring platforms.

This converter is deployed across various critical applications such as steam and gas turbines, hydroelectric generators, and industrial compressors, where accurate shaft displacement and vibration measurements are essential for predictive maintenance and machine protection. Its high-frequency range and fast response time make it ideal for dynamic fault detection and high-speed applications.

The CON021 is built with a rugged design, wide operating temperature range, and an IP65-rated enclosure, ensuring reliable performance in harsh industrial environments. Furthermore, it is compatible with a wide range of sensor models, including PR6422, PR6423, PR6424, PR6425, PR6426, and PR6453, making it highly flexible and suitable for various asset types.

Overview

The EPRO PR6423/13R-010 is a high-performance eddy current sensor system designed for continuous condition monitoring in critical turbomachinery applications. When paired with the CON021 signal converter, it provides highly accurate measurements of radial and axial shaft movement, making it ideal for detecting early signs of mechanical issues.

This system is engineered to excel in tight spaces due to its compact 8 mm probe diameter, without compromising measurement accuracy. Its stainless steel housing and IP68 protection rating ensure that the sensor performs reliably even in high-temperature and high-vibration environments. This system is widely used in power generation, petrochemical, and heavy manufacturing sectors for predictive maintenance and ensuring machinery protection.

The PR6423/13R-010 offers real-time diagnostics and integrates seamlessly with Emerson’s AMS suite and other plant-wide monitoring systems, making it a trusted solution for industrial applications where uptime and reliability are critical.

Technical Data

The PR6423/13R-010 sensor provides high sensitivity, offering stable performance across a wide temperature range and delivering high-speed signal processing for real-time diagnostics. Its non-contact technology ensures long-term durability with minimal maintenance.

Typical Applications

• Steam and Gas Turbines: Monitors shaft movement and vibration for early fault detection and optimized performance.

• Compressors and Pumps: Tracks dynamic displacement to detect imbalances and prevent mechanical failures.

• Fans and Gearboxes: Detects misalignment and eccentricity in rotating components, improving reliability.

• Hydroelectric Equipment: Ensures safe operation of critical components under variable load conditions.

For instance, in refinery settings, the PR6423/13R-010 helps detect imbalance and misalignment before they escalate into costly downtimes, allowing for preventive maintenance and extending equipment lifespan.
