Just as an integral becomes more accurate as it increases its subintervals (the value of “n”), so can industrial processes through offering more data points. Traditionally, a technician might check gauges a few times a day, week, or month. However, if a gauge indicates that nothing is wrong, or it is within an acceptable range, the technician may not make a note of the gauge reading. Attaching a cost-effective sensor able to sample and record raw data multiple times per minute, hour, or day greatly increases the process’s “n” value. Aggregating more raw data points opens the door for statistical software and algorithms to translate raw data into process information to make maintenance or business decisions...
