Condition Based Maintenance (CBM) for motor-operated valves, which sre used in nuclear power statiions and other plants, requires a real-time monitoring during operation. This highly reliable and rational planned maintenance system can safely reduce theperiodical inspection intervals while cutting down maintenance and labor costs, contributing to reduction of exposure. This developed technology evaluates the soundness correctly, Enabling direct detection of the status in the machine that cannot be checked by conventional Methods. Once the sensor is incorporated into apart of motor-operated valve during the periodical Inspection, status monitoring and degradation tendency management can be made, without need of interrupting the operation and touching the valve, simply by attaching the connectors.
