Typical Characteristics
A927ZET Battery Life
The A927ZET battery life depends on the working temperature range and on the sampling interval as follows:

Response Time
In the following figure, the A927ZET temperature response times is shown.
T90 value is the time (measured in seconds) needed by the tag to reach 90% of the change in temperature. If the tag’s
temperature is plotted against time, an exponential graph will result, initially changing quickly then flattening out in the
final stages.
If the tag at 25°C is placed into an environment at 70°C then the temperature change is 45°C (70°C -25°C). 90% of 45°C
is 40,5°C so the T90 value will be the time taken for the tag to go from 25°C to 65,5°C (25°C + 40,5°C), as shown in the
figure below:
