摘要
分析了DS1 82 1数字温度传感器的原理结构、工作方式及操作指令 ,提出用DS1 82 1进行热电偶自由端温度补偿的新方法 ,并将其应用于智能温度测控仪表的设计中 ,它具有准确、线性、完全补偿的特点 ,从根本上解决了桥式冷端补偿器的非线性与型号匹配问题。
The configuration,instruction system and working modes of a digital temperature sensor,DS1821 are described.A new idea is mentioned to use it for free junction compensation of thermocouples used at a temperature measuring system.It is accuracy,linear and well compensation and can match every kind of thermocouple.
