负温度系数热敏电阻器B值测量仪的设计

摘要

This paper presents the principle of a meter for measuring B value of the NTC thermistor.According to this principle,a microprocessor-based circuit diagram is designed.The design of this meter can solve the problems of the on-line B value measurement in the process of production and research.%本文介绍一种负温度系数热敏电阻器B值测量的原理，并根据此原理设计出了基于单片机的实现电路图。该仪器的研制解决了生产及研究中B值的自动检测问题，填补此项仪器研究的空白。
