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 PR6424/003-030 is a high-precision eddy current sensor designed for turbomachinery applications in demanding industrial environments. It is part of Emerson’s trusted AMS suite and provides accurate monitoring of shaft displacement, vibration, and shaft position in high-speed rotating equipment such as steam turbines, gas compressors, and hydroelectric generators.

This sensor operates based on eddy current technology, offering non-contact measurement, which minimizes wear and maintenance requirements. When paired with the CON021 signal converter, the PR6424/003-030 seamlessly integrates into condition monitoring systems, enabling real-time diagnostics and predictive maintenance.

Its rugged stainless steel housing and IP68 protection make it suitable for harsh industrial environments, ensuring long-term reliability and stability across a wide temperature range.

Technical Data

The sensor is vibration-resistant and designed for continuous operation in high-speed rotating machinery, ensuring reliable performance in critical applications.

Typical Applications

• Steam and Gas Turbines: Monitors shaft movement and vibration to detect faults early, preventing catastrophic failure and improving turbine performance.

• Compressors and Pumps: Tracks dynamic displacement and identifies issues like imbalance or misalignment to avoid mechanical failure and downtime.

• Fans and Gearboxes: Detects misalignment and eccentricity in rotating components, ensuring smooth and safe operation.

• Hydroelectric Equipment: Ensures safe operation under variable load conditions by monitoring shaft behavior and detecting irregularities.

For instance, in a refinery, the PR6424/003-030 helps identify issues like imbalance and misalignment before they escalate into costly downtime, improving operational efficiency and reducing maintenance costs.
