The Epro PR6423/005-030-CN+CON021 Eddy Current Sensor System is a complete non-contact displacement measurement assembly used for rotating machinery monitoring and protection applications. It combines the PR6423/005-030-CN 8mm eddy current sensor with the CON021 eddy current signal converter, providing a complete sensing and signal processing solution for industrial condition monitoring systems.
The sensor probe detects the relative distance between the probe tip and a conductive rotating target, such as a machine shaft. By using eddy current measurement technology, the system can continuously monitor shaft displacement and vibration without direct mechanical contact.
The CON021 signal converter processes the sensor output and provides a suitable measurement signal for connection with machinery monitoring equipment. This sensor assembly is commonly used in turbines, compressors, generators, pumps, and other critical rotating machines where early detection of mechanical changes is required.

The Epro PR6423/005-030-CN+CON021 provides a complete measurement chain for industrial rotating machinery monitoring.
Key characteristics include:
The complete assembly should be selected according to the installed monitoring system requirements and equipment configuration.
The PR6423/005-030-CN+CON021 operates based on the eddy current measurement principle.
A simplified measurement path can be represented as:
Rotating Shaft → PR6423 Sensor Probe → CON021 Signal Converter → Monitoring System
The sensor probe produces an electromagnetic field near the conductive shaft surface. When the shaft moves relative to the probe, the distance change affects the eddy current generated within the target material.
The sensor detects these variations and produces an electrical measurement signal. The CON021 converter receives the sensor output, performs signal conditioning, and converts it into a usable signal for machinery monitoring equipment.
This non-contact measurement method allows stable monitoring of high-speed rotating equipment while avoiding mechanical wear between the sensor and the monitored component.
The Epro PR6423/005-030-CN+CON021 is installed in the sensing and signal conversion section of a rotating machinery protection system.
A typical architecture can be represented as:
Rotating Equipment → Eddy Current Sensor → Signal Converter → Monitoring Module → Protection System

Model selection should consider sensor specifications, converter compatibility, installation requirements, and existing monitoring architecture.
The combination creates a complete measurement assembly where the sensor detects shaft displacement changes and the CON021 converter processes the signal for use by machinery monitoring systems.
The assembly is commonly applied to turbines, compressors, generators, pumps, and other rotating machines requiring continuous shaft vibration and displacement monitoring.
The CON021 converts and conditions the sensor output, allowing the measured displacement signal to be correctly transmitted and evaluated by monitoring and protection equipment.
Engineers should confirm the sensor model, converter compatibility, probe clearance, mechanical mounting position, cable connections, and monitoring system configuration.
