When is a Thermistor Needed

Knowing what applications require NTC thermistors will save money and ensure devices run correctly. Thermistors have a long history, and today, they are indispensable from daily life (home appliances, electric vehicles with Li-ion batteries). They are designed to measure temperature, and so the automotive and medical technology industries often use NTC thermistors. A thermistor is needed with devices and applications that generate energy, that requires temperature measurements, and demands strict control and accuracy.


Because of how pervasive they are, due to their wide range in applications, it is not possible for manufacturers to create a single, universal thermistor probe. For instance, the type of thermistor used for measuring coolant temperatures in automobiles differs from thermistors found measuring temperature in wind turbines.

A thermistor is needed to control the temperature comfort levels in a car. Traditionally, a thermostat was used to measure coolant temperature and to manage the cabin climate. Engineers have replaced thermostats with thermistors because thermistors have a faster response time and they give precise measurements.

A thermistor is needed for green energy. One of the many essential components of a wind turbine is a thermistor. Fan blades are equipped with thermistor probes that have two long leads, which are used to sense air temperature and regulate on/off actions of the turbine’s heat (to ensure blades do no freeze or overheat).


A thermistor is needed for modern medical technology. A thermistor is highly accurate, sensitive, and interchangeable, which are all requirements of medical devices. A respirator relies on an NTC thermistor to regulate and compensate as needed.
