Q: What role does the thermistor play in the circuit?
A: Thermistors are used to realize temperature control. The functions of thermistor are temperature compensation and temperature control. Thermistor is a temperature measuring component.
Thermistor is a resistor made of a special material, and its resistance value changes with temperature. According to the different coefficient of resistance change, thermistors are divided into two types: positive temperature coefficient thermistor (PTC), whose resistance value increases with increasing temperature, and negative temperature coefficient thermistor Resistance (NTC), whose resistance value decreases with increasing temperature.
Q: What are the advantages and disadvantages of thermistors?
A: High sensitivity: the temperature coefficient of the thermistor is more than 10-100 times larger than that of metal, and can detect temperature changes as small as 6-10℃; wide operating temperature range: normal temperature devices are suitable for -55℃~315℃, high temperature devices are suitable for temperature above 315℃ (currently the highest can reach 2000℃), the low-temperature device is suitable for -273℃~-55℃; small in size: it can measure the temperature in the space that other thermometers cannot measure.
