Abstract
PURPOSE:To detect the correct abnormal state by obtaining the characteristic data of the load resistance force in a drive range of a driven body each operation time and obtaining the load resistance variation portion by comparing said characteristic data with the career and the initial value in the course from the installation to the present. CONSTITUTION:A CPU 35 records a signal e1 outputted by a valve opening degree encoder 31 each time when a valve body 1 is opening/closing-driven and a signal e2 outputted by a torque encoder 30 in the correspondence state at the same time as the characteristic data of the load resistance corresponding to the opening degree of the valve, together with the data such as the date and time in a built-in calender timer part, into an IC card 38. Therefore, the entire career of the dynamic load variation of the whole device for valve opening/closing operation are recorded into the IC card 38, and the abrasion degree of the valve body 1, valve seat, etc., or the abrasion degree of the driving system can be known by analyzing the recorded data in maintenance inspection, and the correct timing for maintenance inspection and part replacement can be calculated.
