Abstract
PURPOSE: To avoid mis-alarm due to noise, by alarm display when the difference between the value detected at present time point and past time point is greater than the limited change and detected for a given number of times in succession, in the unit monitoring the change with sampling.
CONSTITUTION: The most newest data is stored in the memory unit 6 for the measuring value at normal condition. If there is a failure in the monitored unit, the measuring value is subtracted with the output of the memory unit 6, fed to the compared processor 4, and counted 5 as one limit over number. In this case, the data in the memory unit 6 is not altered, and if the count value is excess of limit value in succession continues for a given number of times, an output is delivered to the alarm unit 8 via the output 7. If the number of limit over of the counter 5 is within a given number, the counter 5 is reset.
