热敏电阻对温度很敏感,所以特别适用于微小温差的测量。在静态测量时,可以分辨小于0.001℃的温差,而且费用不大。传感器的热惯性对于记录不断变化的温度有着决定性作用。下面将叙述,怎样用商业上常见的、价廉物美的热敏电阻制成时间常数相当小的温度传 Thermistors are very sensitive to temperature, so it is especially suitable for the measurement of small temperature differences. In the static measurement, you can tell the temperature difference of less than 0.001 ℃, but not expensive. The thermal inertia of the sensor is decisive for recording the ever-changing temperature. The following will describe how to use the commercially common, inexpensive thermistor made of a relatively small time constant temperature pass
