NTC热敏电阻是最常用的测温型热敏电阻,电阻阻值随温度按指数型变化(如图一)。它的非线性使得它在测量大范围的温度时准确率降低,最常用的测温区间是0-50。热敏电阻的电阻与温度的表达式[5]为:其中Rth(T)是温度为T时热敏电阻的阻值,B是热敏电阻的敏感度,R25是温度为25°C的电阻值。图四:NTC热阻的R-T曲线测温...
NTC thermistors are the most common, and that’s the type we’ll be using in this tutorial. NTC thermistors are made from a semiconducting material (such as a metal oxide or ceramic) that’s been heated and compressed to form a temperature sensitive conducting material. ...
