The PR6424/010-110 CON021 is a high-precision eddy current displacement measurement system primarily used for monitoring shaft vibration and displacement in critical rotating machinery. This system enables non-contact, continuous measurement of equipment such as steam turbines, compressors, motors, and generators, providing stable and reliable data support for equipment operation. By acquiring radial and axial displacement information of the shaft in real time, it helps maintenance personnel promptly detect potential faults such as imbalance, misalignment, and bearing wear, thereby improving equipment safety and operational reliability.
The system consists of a PR6424 series eddy current probe and a CON021 signal converter, featuring high linearity, wide frequency response, and excellent electromagnetic interference resistance. Its robust industrial-grade design allows for long-term stable operation in harsh environments such as high temperature, high vibration, and strong electromagnetic interference. Simultaneously, the system outputs a standardized analog signal, allowing seamless integration with various mechanical protection systems and condition monitoring platforms, providing a crucial data foundation for predictive maintenance and automatic protection.
The PR6424/010-110 CON021 EPRO 16mm Eddy Current Sensor may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

In terms of operating principle, the PR6424/010-110 CON021 operates based on eddy current induction technology. The probe's internal coil generates a high-frequency electromagnetic field. When a conductive metal target (such as a rotating shaft) enters this magnetic field, eddy currents are formed on its surface, changing the coil impedance. This change is proportional to the target distance and is processed by the CON021 converter for signal conditioning and linearization, ultimately outputting a stable displacement or vibration electrical signal, enabling precise monitoring of shaft position and dynamic vibration.
Turbomachinery Monitoring: Used in steam turbines, gas turbines, and water turbines to measure radial and axial shaft vibration.
Rotary Dynamics: Tracks shaft eccentricity, thrust (axial displacement), and differential expansion in large compressors, pumps, and fans.
Mechanical Protection Systems: Can be integrated with systems such as the MMS 6000 or Bently Nevada 3500 to automatically issue alarms or shut down when vibration exceeds thresholds.
Vehicle Sensing: Can be used as a non-contact speed/key pulse sensor to provide phase reference or speed data for diagnostic software.
