摘要
本文中，我们根据水银差计原理研制了一套数显电子真空度计，分辨率高，测压准确可靠，具有数字显示，模拟电压量输出功能，能为自动检测系统提供真空度电压信号．
An electronic vacuonmeter with digital display is designed based on mercury differential principle.This device has high resoution and it is precise and reliable in measuring. It is capable of displaying digits,outputting analog voltage,and provide vacuum voltage singnals for automatic chcck and control system.
