【摘要】 本文讨论真空度自动检测及控制的设计方法。文中以DL-8真空规为例,阐述了微机控制系统按规管测量范围的不同,自动且同步地向规管提供相应的工作参数;以及控制量程的自动转换。提出采用相对偏差计算真空控制所需的调节量,从而实现了在宽量程范围内的有效调节。更多还原

【Abstract】 A design method of measurement and control in vacuum is inve-stigated in this paper.For example,in the different measurement range ofvacuum gauge DL-8,we will explain that microcomputer system is how to giveworking parameters automatically and synchronously.In addition shift of rangeis controled with automatic switch-over,the regulating value of vacuum is co-unted for using relative error,so as to adjust vacuum over the all range.更多还原
