主要性能
壓力繼電器的主要性能有以下幾個(gè)方面。
(1)調(diào)壓范圍
壓力繼電器能夠發(fā)出電信號(hào)的低工作壓力和高工作壓力的范圍稱為調(diào)壓范圍。
(2)靈敏度與通斷調(diào)節(jié)區(qū)間
系統(tǒng)壓力升高到壓力繼電器的調(diào)定值時(shí)，壓力繼電器動(dòng)作接通電信號(hào)的壓力稱為開(kāi)啟壓力；系統(tǒng)壓力降低，壓力繼電器復(fù)位切斷電信號(hào)的壓力稱為閉合壓力。開(kāi)啟壓力與閉合壓力的差值稱為壓力繼電器的靈敏度。差值小則靈敏度高。為避免系統(tǒng)壓力波動(dòng)時(shí)壓力繼電器時(shí)通時(shí)斷，要求開(kāi)啟壓力與閉合壓力有一定的差值，此差值若可調(diào)，則稱為通斷調(diào)節(jié)區(qū)間。
(3)升壓或降壓動(dòng)作時(shí)間
壓力繼電器入口側(cè)壓力由卸荷壓力升至調(diào)定壓力時(shí)，微動(dòng)開(kāi)關(guān)觸點(diǎn)接通發(fā)出電信號(hào)的時(shí)間稱為升壓動(dòng)作時(shí)間，反之，壓力下降，觸點(diǎn)斷開(kāi)發(fā)出斷電信號(hào)的時(shí)間稱為降壓動(dòng)作時(shí)間。
(4)重復(fù)精度
在一定的調(diào)定壓力下，多次升壓(或降壓)過(guò)程中，開(kāi)啟壓力或閉合壓力本身的差值稱為重復(fù)精度，差值小則重復(fù)精度高。 [4] 
選用標(biāo)準(zhǔn)
根據(jù)所測(cè)對(duì)象的壓力來(lái)選用,比如所測(cè)壓力范圍在8KG以內(nèi),那么就要選用額定10KG的壓力繼電器,還有要符合電路中的額定電壓,接口管徑的大小。

威托WATO WDPHE型先導(dǎo)式電液換向閥

 電磁閥分別安裝在主閥的進(jìn)油回路和出油回路中，用于控制主閥的動(dòng)作，當(dāng)兩電磁閥通電時(shí)，進(jìn)油孔（上游閥）回路關(guān)閉，先導(dǎo)孔（下游閥）回路打開(kāi)，活塞上腔泄壓，活塞上行，主閥打開(kāi)。反之，活塞下行，主閥關(guān)閉。在主閥開(kāi)啟和關(guān)閉過(guò)程中，可將流量（流速）信號(hào)及閥塞位置信號(hào)傳送給計(jì)算機(jī)，經(jīng)過(guò)計(jì)算機(jī)處理后發(fā)出相應(yīng)的指令，控制兩個(gè)電磁導(dǎo)閥的通、斷電狀態(tài)，使活塞的上下腔的液壓差產(chǎn)生變化，從而將活塞控制在所需的開(kāi)啟度上，實(shí)現(xiàn)對(duì)管道介質(zhì)流量的控制。
