The WattIQ System employs our Intelisensor product line to continuously monitor temperature, door sensors, or other sensors attached to your equipment. We display the real-time status of equipment that is being monitored to maintain a constant environment, including freezers, incubators, cryogenic storage, water baths, etc.
This documentation article defines the terminology and variables employed in our Asset Condition product.
Certain fields on the Condition > Status display are provided by the customer and are "labels" for the assets. Any label you create can show up on the status display (click the gear icon to add or remove columns), so a comprehensive list of these are not possible, but by default we do display the following labels:
- Equipment Type
- The customer's selected "Location" labels
The key sensor variables on the Status Display are:
Temperature (degrees C): This variable is the reported temperature in Celsius of the RTD probe tip.
Probe Status: This variable reports whether the probe is inserted into a freezer or other device. This is a best estimate calculation -- we compare the probe temperature to the ambient temperature of the IH-302 Sensor Hub unit the probe is attached to, and if the two values are close, we report that the probe is likely NOT inserted into a piece of equipment. Obviously, if the setpoint of the interior of your equipment is equal to ambient temperature, this estimate may be incorrect, but it functions well for most equipment.
Door Status: This variable records the OPEN or CLOSED status of a door on your equipment, using the magnetic sensor.
Power (W): Current power reading, at the time the Status Display refreshes. By clicking "View Asset" using the icon on the right hand side, you can see recent power history and other variables.
Latest Raised Event: This displays the name of the most recent Event Rule which was raised for this device. That event may be recent or in the past. The names seen in this field may be standard event rule names from the WattIQ defaults or customer-specified values.
Latest Raised Event Time: This displays the date and time of the most recent event that occurred. This may be current or in the past depending upon what is happening with your equipment.
When creating reports on the history of events for equipment monitored under WattIQ's Asset Condition product, the following variables are available to aggregate and trend in tabular and graphical reports. In each case, a report has a Time Range selected, over which the variables below can then be displayed for single assets, or aggregated across labels or other asset groups. The variables which can be tabulated in a report are described below.
Total Number of Door Openings: The count of door openings detected during the Time Range of the report. Note that this reflected all door openings detected by the magnetic sensor, not just openings which resulted in an Event being raised.
Average Daily Door Openings: For all of the days in the Time Range selected for the report, this statistic shows the average number of door openings per day. Again, this reflects all openings, not just openings which result in an Event being raised.
Total Time Door Open (minutes): This statistic is the sum of the durations of all door openings in the Time Range selected for the report.
Average Temperature: This is the average RTD probe temperature seen during the Time Range of the report.
Max Temperature: This is the maximum RTD probe temperature seen during the Time Range of the report.
Min Temperature: This is the minimum RTD probe temperature seen during the Time Range of the report.
Number of Door Open Alerts: This counts the number of Events raised which involve the equipment door being open for too long. The threshold for a door opening to raise an Event is defined by the customer under Condition > Event Rules.
Duration of Door Open Alerts: This totals the duration of Door Open Events which involve the equipment door being open for too long. The threshold for a door opening to raise an Event is defined by the customer under Condition > Event Rules. This value will thus be less than or equal to the Total Time Door Open.
Number of Temperature Alerts: This counts the number of Events raised which involve the probe temperature being out of specification (too high or too low) for an excessive period of time. The thresholds for temperatures (one or two-sided) and the length of time those thresholds must be exceeded are defined by the customer under Condition > Event Rules.
Duration of Temperature Alerts: This totals the duration of Temperature Events which involve the probe temperature being out of specification (see previous variable).
Total Energy Consumption: This variable totals the energy consumption of a piece of equipment or group of assets over the Time Range of the report.
Additionally, when making a Trend report to visualize how these statistics change over time, you can select whether multiple assets in each grouping are aggregated. For example, if you wish to understand how "Duration of Door Open Alerts" has trended by equipment model, you might look at the average across assets in each group, or you may wish to see the minimum and maximum values for alert duration for each equipment class.
