摘要
文章阐述了一种自来水电子压力表的设计装置,具有压力系数大小实时现实、存储、查询、报警等功能。该系统采用高精度的传感器来检测压力,低温漂的仪表放大器AD620对数据进行放大,通过8位AD转换器件ADC0808进行AD采集和数据变换处理,并可将数值通过串口发送到电脑,实现压力系数的数字化测量。
This paper expounded the design of a kind of electronic pressure gauge device for tap water,which featured with real-time reality of pressure coefficient,storage,query,alarm,and other functions.The system can detect pressure with high-precision sensors,the instrumentation amplifier of low temperature drift would amplify the figures,collect AD and transform it through ADC0808 and send them to computer via a serial port,so as to realize the digital measurement of the pressure coefficient.
