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 of PR6423/10R-030-CN

The EPRO PR6423/10R-030-CN is a high-performance eddy current displacement sensor developed by Emerson (formerly EPRO) as part of their PR6423 sensor series. This sensor is designed for non-contact measurement of dynamic shaft behavior in high-speed rotating equipment, including gas turbines, steam turbines, compressors, and gearboxes. It measures critical parameters such as shaft vibration, position, and dynamic displacement with high accuracy and fast response times.

The reverse-mount design (10R) allows for installation from behind the target surface, making it especially useful for constrained spaces or rear-access installations. This feature is ideal for environments where physical space is limited, or the sensor needs to be placed behind machinery or other obstructions.

The PR6423/10R-030-CN sensor is typically used in conjunction with the EPRO CON021 converter, which converts the sensor’s analog signal into a standardized output for integration with control and protection systems, such as Emerson’s MMS 6000 and MMS 3000 platforms. The combination of these systems enables predictive maintenance, reducing unplanned downtime and extending the service life of machinery by enabling real-time diagnostics and trend analysis.

With its rugged construction and wide operating temperature range, the PR6423/10R-030-CN is built for reliability in demanding environments, ensuring stable performance under high vibration, dust, and temperature extremes.
