摘要
采用变频式压力传感器的系统,与变阻、变流式压力传感器比较有许多优点,这种方案只需一对测量线即可把一条电缆上的127个传感器连接起来,该设计已用硬件及微机实现.
Compared with resistance-varient and current-varjent pressure sensor, freqency-varient pressure sensor have many advantages.In this kind of design system,only a pair of wires is needed to connect 127 sensors.It has been implemented in hardware and microcomputer.
