All DA-series monitoring stations and Remote Device Controllers have the ability to accumulate hourly statistics for each monitoring point. These statistics include the following:
- Average Value (arithmetic mean) over the hour
- Maximum Value Detected and the Time it was detected during the hour
- Minimum Value Detected and the Time it was detected during the hour
A Special Calculation (see below)
Today, the “Special Calculation” can be either the Variation detected during the hour or the Mean Kinetic Energy (MKT) calculated over the hour. MKT is typically used to monitor areas where pharmaceuticals are stored and is an indication of the stress on the materials caused by increased temperature.
You can currently plot the statistics over any period of time for which they exists. You can also generate a tabular report containing a listing of all the statistical measurements recorded over a specified time period.
A report is also available that will allow you to summarize the statistics over a specified period of time. In other words, it will allow you to see the average value or the maximum value detected over a time period. You can also accumulate the variation or MKT for a period with this report.
Statistics reporting works in tandem with the normal measurement value reporting in CIMScan. Typically, you’d configure your system to do normal alarm detection using the measurement data. You would, however, only log this data for a relatively short period of time (30 days). You would rely on the hourly statistics and the alarm log for long term storage. (The alarm log contains all alerts that were detected.) You could make the measurement update rate fairly quick (1 minute) without excessive database loading.
CIMScan system, as efficient web based environmental monitoring system, provides its users the confidence in monitoring critical applications across various fields.
