温度传感器的响应延迟

Response Delay of Thermal Sensors

在使用温度传感器的过程中 ,我们发现 ,从对热敏电阻加上阶跃信号到输出开始响应 ,总是存在一定的延迟效应。专门设计实验进行研究 ,得出的结论是这个响应延迟与热敏电阻的时间常数τ数量级接近 ,如果忽略这个延迟 ,则会出现重大偏差。

While using the thermal sensors, we find there is a delay time between the time when motivation is putting on and the time when we get the response. After a special experiment, we get the conclusion that this response delay is close to the time constant of the thermistor. If this delay is ignored, there'd be a great deviation.
