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 PR6424/001-110 is an advanced eddy current sensor system designed for continuous condition monitoring in critical turbomachinery applications such as steam turbines, compressors, and hydroelectric generators. Utilizing eddy current technology, it provides precise measurement of radial and axial shaft movement, enabling early fault detection and predictive maintenance.

The sensor's stainless steel housing and IP68 protection rating ensure long-term durability and reliable operation even in high-temperature and high-vibration environments. Its non-contact design reduces mechanical wear, significantly lowering maintenance costs and increasing uptime. As part of Emerson’s AMS suite, the PR6424/001-110 reflects the company's legacy of engineering excellence and reliability.

This sensor system is widely used in power generation, petrochemical, and heavy manufacturing sectors, helping to monitor machinery conditions and improve operational safety.

Technical Data

The PR6424/001-110 offers outstanding frequency response and linearity, making it ideal for dynamic shaft monitoring in complex rotating machinery. Additionally, its CON021 signal converter provides a fast rise time for real-time diagnostics and seamless data integration with plant-wide monitoring systems.

Typical Applications

• Steam and Gas Turbines: Monitors shaft movement and vibration to prevent faults and optimize performance.

• Compressors and Pumps: Tracks dynamic displacement to detect imbalances, misalignments, and potential failures.
