70年代中期以前的發(fā)展
20世紀(jì)，自動化科學(xué)技術(shù)的建立以及工業(yè)的發(fā)展，逐漸形成了自動化儀表工業(yè)。50年代以前，PID調(diào)節(jié)已很流行，但集檢測、調(diào)節(jié)、執(zhí)行功能于一體的基地式儀表仍為主流熱工儀表。功能分離、信號傳輸、中央控制室集中顯示操作，這種可應(yīng)用于多個行業(yè)的通用性強(qiáng)的自動化儀表模式還在醞釀之中。
60年代，以電子管為基礎(chǔ)的DDZ－I型電動單元組合儀表，被以晶體管分立元件為基礎(chǔ)的DDZ-II型電動單元組合儀表取代。這是面向石油、化工、冶金、電力、建材等行業(yè)，以溫度、壓力、流量、液位為主要控制參數(shù)的整套工業(yè)自動化儀表。這個時期由于生產(chǎn)設(shè)備的大型化，已經(jīng)有了中央控制室，基地式儀表的操作方式逐步被取代，但各單元儀表之間的連絡(luò)信號還不統(tǒng)一，以直流0～10mA的電流信號應(yīng)用較廣。
70年代，一機(jī)部組織了DDZ－Ill型儀表的統(tǒng)一設(shè)計工作。DDZ-III型是在線性集成電路（運算放大器）技術(shù)、國際統(tǒng)一信號、本質(zhì)安全防爆等技術(shù)的基礎(chǔ)上發(fā)展起來的，與此同時，組裝式儀表裝置也在興起。
60年代末70年代初，國際電工委員會IEC規(guī)定了國際統(tǒng)一信號為直流4～20mA，直流l～5V為輔助信號。即以4～2（ADC為傳輸信號，以1～5VDC為接收信號。這個國際統(tǒng)一信號在當(dāng)時執(zhí)行起來，基本沒有多大阻力，原因是其技術(shù)先進(jìn)、切實可行，而且原來的制造廠和用戶都迫切希望有統(tǒng)一的信號制。
DDZ－III型儀表總體設(shè)計時，為了順應(yīng)500萬噸／年原油處理量的大型煉油廠的自控系統(tǒng)的要求，一是系統(tǒng)要求本質(zhì)安全防爆，二是要考慮現(xiàn)場儀表與中控室距離較遠(yuǎn)（約500米以內(nèi)）。在符合國際統(tǒng)一信號的基礎(chǔ)上，選用24VDC統(tǒng)一供電和兩線制變送器及安全柵的方案。當(dāng)時線性集成電路和晶體管的水平能做到在24VDC供電條件下，控制室儀表外接導(dǎo)線電阻與兩線制變送器內(nèi)阻或執(zhí)行器內(nèi)阻串聯(lián)，可具有恒流性能。4mA是為了保證兩線制變送器放大器工作點必要的供電而設(shè)的。在要求防爆的場所，也能夠承受24VDC、20mADC或比它稍高的電量，所以能滿足上述兩項要求。
DDZ-III型儀表的差壓（壓力）變送器，已經(jīng)采用矢量機(jī)構(gòu)的力平衡式的原理，比原來的位移式變送器機(jī)雙杠桿力平衡式變話器有較大的進(jìn)步。
