摘要
本文介绍了利用半导体致冷件,对具有一定热源物体降温的温度显示电路,并对其工作原理进行了分析。通过实验,总结出了一种性能稳定,测试方便,电路简单、实用较强的数字式温度显示电路。该电路使用了集成运放电路及ICL7107大规模集成电路A/D转换器,可进行-50~100℃范围内的物体或周围环境温度的测量。
n the present paper we give the analysis of temperature displaying circuit with reducing temperature of a heat reservoir object and its work principle.From the experiment we give a digital temperature display circuit with function stability,conveniently measuring,simple circuit and easy application.In this circuit integrated analog/digit converters and A/D converter with a large-scale integrated circuit ICL 7107 are used.The circuit can be applied to measure objects or surroundings in the termperature range of -50~100℃.
