1756-RM2

80年代，差压变送器中采用了半导体制造工艺，省去了原来力平衡式仪表的大量机械零件，解决了抗振性差、抗静压能力差、对安装位置要求严等问题，使性能有了很大进步。国内通过合资引进了电容式、扩散硅式、硅谐振式等多种原理的变送器制造技术，满足了国内用户的需要。其它的流量变送器也有多项新技术引进。近年来变送器数字化、智能化的发展也进展很快。与变送器相比，执行器虽有进步，但是引进和技术进步尚需努力，这可以由每年现场大修的工作量来看，调节阀等维修量是相当可观的。电子秤等物料重量和流量的测量仪表、速度的测量和控制仪表（特别是交流电动机的变频调速器）、成分分析的在线测量和控制、多种电量的在线测量和变送、无线的遥测、遥讯、遥控等等都已形成了成熟的产品。80年代以来，微机的使用特别是PC机的普及，使系统集成成为自动化系统成套工程产业的新潮流。管理和控制一体化的CIMS和CIPS系统是一个热点，电控和仪控一体化是另一个热点。而集成的系统已由多级递阶结构向扁平化方向发展，特别是近几年兴起的现场总线热和互联网热（Internet和Intranet）更使系统集成出现了日新月异的局面。
