本文介绍一种新型的自热式热敏电阻测温电桥的设计方法。该电桥可以不受热敏电阻自热的局限,具有比通常热敏电阻测温电桥高得多的灵敏度,有三点线性化的输出特性,在±10℃的测温范围内,可获得0.1℃的测温精度。 This article describes a new type of self-heating thermistor temperature bridge design method. The bridge can be free from the limitations of the thermistor self-heating, with a thermistor bridge thermistor generally much higher than the sensitivity of the three-point linear output characteristics, in ± 10 ℃ temperature range, available 0.1 ℃ temperature measurement accuracy.
