一談(tan)到反應釜控(kong)制(zhi)器(qi)，就不(bu)得(de)不(bu)談(tan)談(tan)轉速的控(kong)制(zhi)。

轉速的控(kong)制分三種情(qing)形：

一(yi)、由PC控(kong)(kong)制：在電(dian)加熱(re)的情(qing)況下，反(fan)應釜的溫(wen)度與(yu)轉速統一(yi)由PC控(kong)(kong)制。控(kong)(kong)制軟件設(she)有攪拌器“開/關(guan)"鍵，可以設(she)置轉速的快(kuai)慢(man)。

二、由轉速(su)顯(xian)示(shi)與控(kong)(kong)(kong)(kong)制器控(kong)(kong)(kong)(kong)制：在硅油加熱的(de)情(qing)況下，恒溫器只控(kong)(kong)(kong)(kong)制溫度并顯(xian)示(shi)壓力，但(dan)不控(kong)(kong)(kong)(kong)制轉速(su)。這(zhe)個(ge)時候，必須有獨立的(de)轉速(su)顯(xian)示(shi)與控(kong)(kong)(kong)(kong)制器來控(kong)(kong)(kong)(kong)制。瑞(rui)士Premex Solutions Gmbh公司生產的(de)DZA3與DZA8就是這(zhe)種類型的(de)控(kong)(kong)(kong)(kong)制器。DZA3是用來控(kong)(kong)(kong)(kong)制三相電(dian)流的(de)交流電(dian)電(dian)機(ji)(ji)，DZA8是用來控(kong)(kong)(kong)(kong)制直流電(dian)電(dian)機(ji)(ji)（微電(dian)機(ji)(ji)）。

三、手動控制：當(dang)三相交流電(dian)電(dian)機配有(you)減速器(qi)時(shi)，就可以手動控制減速器(qi)的(de)檔(dang)位。這個(ge)時(shi)候既不需(xu)要PC控制也不需(xu)要轉速顯(xian)示與控制器(qi)控制。
