In any of the temperature sensitive areas it is essential that the temperature has to be monitored continuously.
Typical examples of such sensitive areas are:
An over temperature warning system consists of a temperature sensor combined with an warning system. The temperature sensor will be continuously monitoring the temperature. The sensor can be programmed to check the temperature at different intervals.
The second element of the system is an alert system. The alert can be different types. In case the temperature goes above or below the programmed levels, the following warning can be generated:
Depending on the critical nature of the area being monitored, the interval can be programmed. This interval is known as sampling interval.
For a cold room of 2-8°C, the sampling interval is set between 1 and 3 minutes. The reason is that this is a narrow range of temperature. Also you may not want the temperature to go beyond the limits even for couple of minutes. Hence the sampling interval is kept at low levels. The recommended sampling interval is not more than 3 minutes.
Whereas for a warehouse of temperature range between 15-25°C, the sampling interval can be set at 10 or 15 °C.
The higher and lower alarms have to be programmed in the system. Eg. If you want the temperature of the cold room to be between 2 and 8°C, you can set the alerts as below:
Higher warning should be activated if the temperature goes above 7.5°C for 5 minutes
Lower warning should be activated if the temperature goes below 2.5°C for 5 minutes
You may notice that the higher alert level is kept 0.5°C below the permitted level so that if a warning is generated, someone can attend the problem before it crosses 8°C. Also you may notice that there is a time delay of 5 minutes programmed. The reason is to avoid false alarms, probably caused by temporary conditions such as a door opening. When a door is opened, the temperature may go above 7.5°C briefly. You may not want to have warnings at such short excursions.
You may decide to combine following alerts in the same system
