PR6423/018-140 CON021 EPRO Eddy Current Sensor is a high-performance, non-contact displacement and vibration monitoring system designed for critical turbomachinery applications. It combines the PR6423 eddy current probe with the CON021 signal converter, enabling precise monitoring of shaft displacement, eccentricity, vibration, axial position, and rotational dynamics in rotating equipment. The system is particularly suited for harsh industrial environments where high reliability and continuous condition monitoring are essential. It is widely used in steam turbines, gas turbines, hydro turbines, compressors, pumps, fans, generators, and gearboxes for predictive maintenance and machinery protection. Operating based on the eddy current measurement principle, the PR6423/018-140 CON021 provides non-contact sensing, eliminating mechanical wear and minimizing measurement distortion caused by friction or vibration transmission through bearing housings. This makes it especially effective for sleeve-bearing machinery, where shaft movement is better monitored directly rather than through case vibration analysis. The integrated CON021 signal converter performs signal conditioning and linear amplification, transforming raw sensor signals into stable, process-compatible outputs for machinery monitoring systems, distributed control systems (DCS), and protection platforms. The sensor system is optimized for accurate measurement of radial shaft vibration, thrust position, differential expansion, air gap monitoring, and shaft eccentricity detection. |

FAQ
PR6423/018-140 CON021 is engineered as a high-precision eddy current measurement system optimized for non-contact shaft monitoring in critical rotating assets. It provides exceptionally reliable measurements of radial shaft displacement, axial position, eccentricity, and dynamic vibration in severe industrial environments, particularly within turbines, compressors, pumps, and gearboxes. Its signal fidelity and high-frequency responsiveness make it indispensable for predictive maintenance architectures.
PR6423/018-140 CON021 operates through the eddy current principle, enabling non-intrusive displacement measurement without physical contact with the target surface. This eliminates mechanical wear, mitigates friction-induced inaccuracies, and preserves metrological integrity even in environments characterized by elevated temperatures, vibration loads, and contaminants.
The architecture of PR6423/018-140 CON021 supports real-time dynamic monitoring with rapid signal response characteristics and broad frequency capability. Such attributes permit early anomaly detection, including rotor imbalance, shaft misalignment, eccentric motion, and bearing degradation, thereby strengthening machinery reliability programs and minimizing unscheduled downtime.
PR6423/018-140 CON021 is prevalently implemented in power generation facilities, petrochemical complexes, process industries, and heavy manufacturing environments. Typical deployments include steam turbines, gas turbines, centrifugal compressors, generators, industrial pumps, and gearbox monitoring systems requiring high-accuracy rotor behavior assessment.
Depending on system configuration and calibration, PR6423/018-140 CON021 can support multiple diagnostic modalities, including shaft displacement measurement, relative vibration analysis, eccentricity evaluation, position tracking, and rotational speed or keyphasor-related monitoring. This multifunctionality enables comprehensive machinery health assessment.
