Function and Position

This module is positioned as a professional shaft displacement monitoring unit, mainly used for real-time collection and processing of signals returned by eddy current sensors, accurately monitoring the axial displacement of rotating machinery rotors. It has complete front-end signal processing functions such as signal filtering, amplification, noise reduction, analog-to-digital conversion, and data calculation. It can filter out on-site interference noise and output real and effective monitoring data. The module is equipped with hierarchical alarm logic and supports custom monitoring thresholds. When the shaft displacement value exceeds the preset safety range, it will trigger local status indication and simultaneously transmit real-time data and alarm signals to upper-level devices such as DCS, PLC, data acquisition systems, etc., achieving local early warning and remote monitoring linkage.

As a key transfer device between sensors and the central control system, this module assumes the core responsibilities of data acquisition, status judgment, signal transmission, and over-limit alarm. It can independently complete single-point monitoring or integrate with other modules of the same series to build a comprehensive monitoring system, serving equipment status management, safety interlock protection, operation data analysis, etc. It is an important unit for ensuring the safe operation of shafting equipment.
