摘要
本文介绍采用ＡＤ６９３ 制成的压力变送器，可用于各种不同的传感器接收的小信号电压输入控制１ 个４ ～２０ｍ Ａ的标准二线制电流环。
A kind of pressure transmitter which is made of AD693 is described in this paper. This transmitter accepts low-level inputs from a variety of transducers to control a standard 4～20mA,tow-wire current loop.The circuits suitable for different input resistance and work current have been designed
