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 PR6423/003-030 is a high-precision eddy current sensor designed for condition monitoring in demanding turbomachinery applications. Part of Emerson’s AMS suite, this sensor is engineered to measure radial displacement, vibration, and shaft position with great accuracy, making it ideal for use in steam turbines, gas compressors, hydroelectric generators, and other high-speed rotating equipment.

Paired with the CON021 signal converter, the PR6423/003-030 delivers real-time data and seamlessly integrates with industrial monitoring systems. Its rugged stainless steel housing and IP68 protection ensure reliable operation in harsh environments, including high-temperature and high-vibration settings. With its high sensitivity and wide operating temperature range, this sensor is well-suited for predictive maintenance and helps reduce unplanned downtime.

Technical Data

This sensor is designed for continuous operation in high-speed rotating machinery and can withstand harsh conditions such as vibration and temperature extremes.

Typical Applications

• Steam and Gas Turbines: Monitors shaft displacement and vibration for early fault detection, preventing catastrophic failures and downtime.

• Compressors and Pumps: Tracks dynamic displacement to identify issues like imbalance, misalignment, and bearing wear, ensuring reliable operation.

• Fans and Gearboxes: Detects misalignment and eccentricity in rotating components, which can lead to failures if left unchecked.

• Hydroelectric Equipment: Provides real-time monitoring of shaft position and vibration under variable load conditions, ensuring safe and efficient operation.

In refinery settings, for instance, the PR6423/003-030 helps identify issues like imbalance or misalignment before they lead to costly unplanned downtime.
