压力表自动检定仪的设计

利用单片机、步进电机驱动器、步进电机为主要硬件,构建压力表自动检定装置。根据检定规程要求,由单片机控制造压系统,由键盘设置压力点,实现检定过程自动化。装置自动采集标准压力值,自动计算示值误差、回程变差、轻敲位移。保存检定数据、打印检定结果。

Design of automatic verification instrument pressure gauge

Using microcomputer,stepper motor driver,stepper motor as the main hardware,construction of automatic inspection device for pressure gauge.Pressure created by the SCM system,pressure points from the keyboard settings,automate the process of achieving certi？cation.Device automatically collect standard pressure value,automatically calculate the error of indication,the return variation,tapping displacement.Save the test data,print test results.
