从事电子行业的朋友们，应该对热敏电阻不陌生吧！那么笔者在这里抛出一个问题：你知道NTC热敏电阻是什么吗？ 百度百科上给的定义是：热敏电阻是一种传感器电阻，其电阻值随着温度的变化而改变。按照温度系数不同分为正温度系数热敏电阻（PTC thermistor ...

----- 正文 -----一、NTC电阻的基本特性 1. R-T曲线 下图是一个常温（25℃）下阻值1K的NTC电阻的R-T曲线，观察曲线发现它的阻值是随温度上升而下降，这也是它叫NTC（Negative Temperature Coefficient-负温度系数）电阻的原因，对应的还有PTC（Positive ...

Temperature is the most widely measured physical variable and designers have many sensing options, among them thermocouples, RTDs, solid-state current-output sensors, and thermistors, to cite just a ...
