摘要
介绍两种实用的铂电阻４～２０ｍＡ电流变送器电路，不仅能将铂电阻进行线性化处理，而且可将温度转换成与之成正比的电流信号进行远距离传输。
This paper introduces two kinds of practical circuits which are 4~20mA current transmitter for platinum resistance temperature detector (RTD). Not only can it linearize the platinum RTD but also convert temperature into current signal in direct ratio for transmitting a long distance.
