Characteristics

[1]

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.
