The main use of a thermistor is to measure the temperature of a device. In a temperature controlled system, the thermistor is a small but important piece of a larger system. A temperature controller monitors the temperature of the thermistor. It then tells a heater or cooler when to turn on or off to maintain the temperature of the sensor.

NTC thermistor temperature sensors are a key component in Li-Ion battery charging and safety. They provide critical temperature data required to keep the Li-Ion battery in the optimum condition during the charging cycle. Careful management of temperature during charging prolongs battery life and avoids hazards inherent to Li-Ion batteries.
If you can wrap the thermistor in a waterproof heatproof enclosure (say, copper pipe soldered shut on one end) then an easy way to produce known temperatures is to use water''s phase changes. Boiling water is at 100 °C (with correction for your local air pressure based on altitude).
The energy the thermistor needs to handle without self destruction is 18.0 J (120 V x 7.50 A for 0.02 s). So, for three appliances that start up at the same time, 54 J is needed (3 x 18.0 J). A minimum resistance of 21.21 Ω (peak voltage/maximum allowable current: 120 V x 1.414/8.0 A) ensures that the current does not exceed 8.0 A.
