Introduction & Technical Overview
The Epro PR6423/003-130 combined with the CON021 signal conditioner is a high-precision eddy current proximity measurement system designed for continuous monitoring of rotating machinery. The probe performs non-contact displacement sensing, while the CON021 module converts and conditions the raw signal into a stable industrial output suitable for protection and monitoring systems.
This system is engineered for long-term deployment in critical rotating equipment where stable signal integrity, environmental resistance, and predictive maintenance capability are essential. It is widely used in high-speed turbomachinery and heavy industrial drive systems where even small deviations in rotor behavior must be detected early.

Applications
The system is typically used in turbine monitoring, compressor vibration analysis, pump shaft displacement tracking, and generator rotor condition monitoring. It plays a key role in both protection systems and predictive maintenance architectures.
In power generation plants, it continuously monitors rotor dynamics to detect imbalance, misalignment, or developing mechanical faults. In oil and gas facilities, it is integrated into compressor train monitoring systems to ensure operational stability under high load conditions. It is also used in industrial plants requiring high-availability rotating equipment monitoring with minimal downtime tolerance.
Advantages
The PR6423 probe combined with the CON021 conditioner provides high measurement accuracy and long-term signal stability. The eddy current principle ensures that measurements are unaffected by oil, dust, humidity, or other non-conductive contaminants commonly found in industrial environments.
The separation between probe and signal conditioning unit improves system flexibility and simplifies maintenance. Individual components can be replaced without requiring full system recalibration, reducing downtime and operational cost.
The system also supports high-frequency dynamic measurement, making it suitable for both steady-state monitoring and transient event detection in rotating machinery.
