電磁閥有很多種，不同的電磁閥在控制系統(tǒng)的不同位置發(fā)揮作用，常用的是單向閥、安全閥、方向控制閥、速度調(diào)節(jié)閥等。

功率因數(shù)指有功功率和視在功率的比值，一般用符號λ表示，即：λ=p/s.在正弦交流電路中，功率因數(shù)等于電壓與電流之間的相位差（ψ）的余弦值，用符號cosψ表示。此時，cosψ=λ。

電壓表是測量電壓的一種儀器。由永磁體、線圈等構(gòu)成。電壓表是個相當大的電阻器，理想的認為是斷路。初中階段實驗室常用的電壓表量程為0~3v和0~15v。

目前，開關(guān)電源以小型、輕量和-率的特點被廣泛應(yīng)用幾乎所有的電子設(shè)備，是當今電子信息產(chǎn)業(yè)飛速發(fā)展不可缺少的一種電源方式。

電壓互感器（potential transformer 簡稱pt，voltage transformer也簡稱vt）和變壓器類似，是用來變換線路上的電壓的儀器。

過流繼電器的動作原理是復(fù)合式的,它由感應(yīng)式和電磁式的兩個元件組成,兩個元件公用一個線圈。閥體是氣動調(diào)節(jié)閥的調(diào)節(jié)部件，它直接與調(diào)節(jié)介質(zhì)接觸，調(diào)節(jié)該流體的流量。電動球閥是工業(yè)自動化控制系統(tǒng)中的重要執(zhí)行機構(gòu)。電動球閥是根據(jù)閥瓣的這種移動形式繞閥桿的軸線作旋轉(zhuǎn)運動的閥門。閥座通口的變化是與閥瓣行程成正比例關(guān)系。電壓保護繼電器是一種多功能三相三線制電源系統(tǒng)或三相用電設(shè)備的監(jiān)測和保護儀器。

電流互感器是由閉合的鐵心和繞組組成。它的一次側(cè)繞組匝數(shù)很少，串在需要測量的電流的線路中。

頻率表是指測量頻率的機械式指示電表。頻率表種類很多，有電動系、鐵磁電動系和屬于整流式的變換器式頻率表等。生產(chǎn)現(xiàn)場用來監(jiān)測頻率用的安裝式頻率表，大多采用鐵磁電動系電表的測量機構(gòu)。

氣動閥采購時只明確規(guī)格、類別、工壓就滿足采購要求的作法，在當前市場經(jīng)濟環(huán)境里是不完善的因為氣動閥制造廠家為了產(chǎn)品的競爭，各自均在氣動閥統(tǒng)一設(shè)計的構(gòu)思下，進行不同的-，形成了各自的企業(yè)標準及產(chǎn)品個性。因此在氣動閥采購時較詳盡的提出技術(shù)要求，與廠家協(xié)調(diào)取得共識，作為氣動閥采購合同的附件是十分-的。
