Notes
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.
2.Inert liquid, e.g. FC43 manufactured by the 3M company.
