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 PR6423/002-130 is a high-precision eddy current sensor designed for accurate monitoring of shaft displacement and vibration in high-speed rotating equipment. This non-contact sensor integrates seamlessly with the CON021 signal converter to provide real-time diagnostics, making it ideal for predictive maintenance and early fault detection.

Engineered for harsh industrial environments, the PR6423/002-130 is widely used in critical applications such as steam turbines, compressors, and gearboxes. The non-contact measurement principle reduces wear and maintenance needs, while its wide frequency range and high sensitivity enable precise detection of shaft position, eccentricity, and dynamic movement.

The sensor’s robust construction (with stainless steel housing) and IP68 protection rating make it reliable for continuous operation in extreme conditions. It is part of Emerson’s AMS suite, benefiting from decades of field experience and engineering excellence.

Technical Data

The sensor is vibration-resistant and designed for continuous operation in high-speed machinery, ensuring long-term reliability even in demanding conditions.

Typical Applications

• Steam and Gas Turbines: Monitors radial and axial shaft displacement to optimize turbine performance and detect faults early.

• Compressors and Pumps: Identifies vibration anomalies and mechanical wear in real time to avoid unplanned downtime.

• Gearboxes and Fans: Detects shaft eccentricity and misalignment, ensuring safe operation and preventing failure.

• Hydroelectric Equipment: Ensures safe and efficient operation under variable load conditions by tracking shaft behavior.

In applications like refineries, the PR6423/002-130 helps identify imbalance and misalignment before they escalate into costly downtime. By integrating with the CON021 converter, the system supports seamless data acquisition and plant-wide monitoring.
