How to measure whether the thermistor of the induction cooker is broken?
Thermistors are a type of sensitive element. They are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to their temperature coefficients. Thermistors are typically sensitive to temperature and exhibit different resistance values at different temperatures. When the temperature is higher, the higher the resistance value, the negative temperature coefficient thermistor (NTC) the higher the temperature, the lower the resistance value, they belong to the semiconductor device (PTC).
Measured with a multimeter, 25 degrees, usually 100 thousand euro, greater than 25 degrees, less than 100 thousand ou, less than 25 degrees, greater than 100 thousand ou;
The thermistor will be in a state of no action for a long time. When the ambient temperature and current are in the C area, the heat dissipation power of the thermistor is close to the heating power, so it may or may not move. Thermistor in the same temperature, action time is shortened sharply with the increase of current; maintain the current and operating current action time and smaller thermistor has shorter when the environment temperature is relatively high.
