HART通用压力变送器的设计压力变送器采用的传感器通常需要不同电路与之配合使用，这就造成产品种类较多，不宜量产。一种崭新的设计思想，设计出的新型电路可以提供软件可控的恒压、恒流输出给传感器，并可以采集两路差分或四路单端输入信号。(HART universal pressure transmitter pressure transmitter used in the design of sensors usually used in conjunction with the different circuits, which result in more product categories, not mass production. A brand new design ideas, to design a new circuit can provide software controlled constant voltage, constant current output to the sensor and can capture two-way differential or four single-ended input signals.)
