近十年来,大规模集成电路工艺技术的迅速发展,引起了仪器仪表产品结构的更新换代。数字式面板表便是一例,国外一些工业比较先进的国家,已经普遍采用它代替指针式面板表。一、数字式面板表简介数字式面板表又称数字式安装仪表(简称 DPM),出现于1967年前后,1970年以后迅速发展起来。半导体器件厂家为数字式而板表设计、生产了专用大规模集成电路,
Over the past decade, the rapid development of large-scale integrated circuit technology has aroused the upgrading of the instrumentation product structure. Digital panel table is an example, some foreign countries more advanced countries, it has been widely used instead of pointer panel table. First, the introduction of digital panel meter Digital panel meter, also known as digital installation meter (referred to as DPM), appeared in 1967 around the rapid development after 1970. Semiconductor device manufacturers for the digital and board design, production of dedicated large-scale integrated circuits,
