Applications and Attentions

Applications:

General Type: industrial electric power temperature measurement

Special Type: human body temperature measurement

Attentions:

► YY-MSA type temperature measurement module is severely affected by the fluctuation of ambient temperature, it is forbidden to be tested by bare machine, or to be used in a thermal shock way, such as direct blowing at the air conditioning port.

► When the shell installed and powered on, the module temperature can be measured accurately because the module needs to reach the thermal balance with the ambient temperature. When the thermal balance is reached, the ambient temperature is allowed to change slowly, such as the heating of the housing. According to experience, the heat balance time is 15~25 minutes (depending on the heating and insulation of different housing).
