The thermal time constant is the time taken for the sensor to reach 63.2 % of the total temperature difference. For example, if a sensor
with a temperature of 25
°C
is moved to an environment with an ambient temperature of 100
°C,
the time for the sensor to reach a
temperature of 72.4
°C
is the thermal time constant.
