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 PR6424/010-110 is a high-precision eddy current sensor system designed for continuous condition monitoring in demanding industrial applications. Paired with the CON021 signal converter, it provides accurate measurements of shaft dynamics, including radial displacement, eccentricity, and vibration amplitude, making it ideal for turbomachinery applications such as steam turbines, gas compressors, and hydroelectric generators.

This system's non-contact design reduces mechanical wear, improving uptime and reducing maintenance costs. The stainless steel housing and IP68 protection rating ensure it can withstand high-temperature, high-vibration, and harsh environmental conditions. Part of Emerson’s AMS suite, the PR6424/010-110 reflects decades of reliability and engineering excellence, making it a trusted choice for predictive maintenance and machinery protection.

Technical Data

The CON021 converter supports a frequency range of 0 to 20,000 Hz and offers a fast rise time under 15 μs, ensuring high-precision data capture.

Typical Applications

• Steam and Gas Turbines: Monitors shaft movement and vibration for early fault detection, allowing for quick intervention and minimizing downtime.

• Compressors and Pumps: Tracks dynamic displacement to identify issues like imbalance or misalignment, preventing mechanical failure and increasing asset life.

• Fans and Gearboxes: Detects eccentricity and misalignment in rotating components, helping to maintain operational efficiency.

• Hydroelectric Equipment: Ensures safe operation under variable load conditions by monitoring shaft displacement and vibration in real time.

For instance, in a refinery, the PR6424/010-110 can help identify early signs of imbalance and misalignment, preventing unplanned shutdowns and extending the lifespan of machinery.
