WebHow Does a Thermistor Work in a Controlled Environment? Thermistors are commonly used to measure the internal temperature of electronic devices. A thermistor provides feedback to a temperature controller that monitors the thermistor’s temperature and turns heating and cooling elements on or off to keep it at a desired temperature. WebWhen the circuit is turned on, the PTC thermistor has a low resistance, allowing current to pass through the startup winding. As the motor starts, the PTC thermistor heats up and at one point switches to a high resistance state. The time needed for this to occur is calculated based on the required motor startup time. WebThermistors are available in a variety of resistances and “curves”. Resistances are normally specified at 25°C (77°F). How does a thermistor work? Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves.
