单片微机在数字压力计中的应用

Application of Single Chip Microcomputer in Digital Pressure Indicator

用二元分段线性——线性插值法对压力传感器的非线性误差及温度误差进行了综合修正.设计了以单片机为核心的微机数据采集与处理系统,该系统在仪器仪表的智能化应用中具有一定的通用性.

In this paper,nonlinear and temperature error of pressure sensor are correted oy using binary linear interpolation method.It is designed by the microcomputer da ta precssing and collection system,in which the single chip microcomputer isthe core.This system is also applicable to other intelligent instruments and methods.
