電壓表是測量電壓的一種儀器，常用電壓表——伏特表的符號為“v”。

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。電動執(zhí)行器的行程可分為：90°角行程和直行程兩種，特殊要求還可以滿足180°、270°、360°全行程。由角行程的電動執(zhí)行器配合角行程的閥使用，實現(xiàn)閥門90°以內(nèi)旋控制管道流體通斷；直行程的電動執(zhí)行器配合直行程的閥使用，實現(xiàn)閥板上下動作控制管道流體通斷。漏電繼電器可與帶分勵脫扣器或失壓脫扣器的斷路器、交流接觸器、磁力啟動器等組成漏電保護裝置，作漏電和觸電保護之用，也可配備蜂鳴器、信號燈等各種聲光器件結(jié)合組成漏電報警裝置。

開關(guān)電源是利用現(xiàn)代電力電子技術(shù)，控制開關(guān)管開通和關(guān)斷的時間比率，維持穩(wěn)定輸出電壓的一種電源，開關(guān)電源一般由脈沖寬度調(diào)制（pwm）控制ic和mosfet構(gòu)成。隨著電力電子技術(shù)的發(fā)展和-，使得開關(guān)電源技術(shù)也在不斷地-。當(dāng)主設(shè)備或輸配電系統(tǒng)出現(xiàn)過負荷及短路故障時，該繼電器能按預(yù)定的時限-動作或發(fā)出信號，切除故障部分，-主設(shè)備及輸配電系統(tǒng)的安全。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(dāng)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(biāo)準(zhǔn)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。

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。繼電器通常應(yīng)用于自動化的控制電路中，它實際上是用小電流去控制大電流運作的一種“自動開關(guān)”。故在電路中起著自動調(diào)節(jié)、安全保護、轉(zhuǎn)換電路等作用。

電磁閥用在工業(yè)控制系統(tǒng)中調(diào)整介質(zhì)的方向、流量、速度和其他的參數(shù)。電磁閥可以配合不同的電路來實現(xiàn)預(yù)期的控制，而控制的精度和靈活性都能夠-。

繼電器具有控制系統(tǒng)（又稱輸入回路）和被控制系統(tǒng)（又稱輸出回路）之間的互動關(guān)系。

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。
