style="text-indent:25px">音叉式液位開關(guān)是一種新型的液位開關(guān)。它是利用音叉振動(dòng)的原理設(shè)計(jì)制作的。它是在音叉液位開關(guān)的感應(yīng)棒底座，透過壓電晶片驅(qū)動(dòng)音叉棒，并且由另外一壓電晶片接受振動(dòng)訊號(hào)，無錫音叉液位開關(guān)生產(chǎn)廠家，使振動(dòng)訊號(hào)得以循環(huán)，并且使感應(yīng)棒產(chǎn)生共振。當(dāng)物料與感應(yīng)棒接觸時(shí)，振動(dòng)訊號(hào)逐漸變小，直到停止共振時(shí)，控制電路會(huì)輸出電氣接點(diǎn)信號(hào)。由于感應(yīng)棒感度由前端向后座依次減弱的自然原理，無錫音叉液位開關(guān)生產(chǎn)廠家，所以當(dāng)桶槽內(nèi)物料與桶周圍向上堆積，觸及感應(yīng)棒底座〈后部〉或排料時(shí)，無錫音叉液位開關(guān)生產(chǎn)廠家，均不會(huì)產(chǎn)生錯(cuò)誤訊號(hào)。簡(jiǎn)單的說，音叉在壓電晶體激勵(lì)下產(chǎn)生機(jī)械振動(dòng)，這種振動(dòng)具有一定的頻率和振幅。當(dāng)音叉被液體或固體浸沒時(shí)，音叉的振動(dòng)頻率和振幅將發(fā)生變化。這個(gè)頻率變化由電子線路檢測(cè)出來并輸出一個(gè)開關(guān)量。液位開關(guān)就是通過液位來控制線路通斷的開關(guān)。無錫音叉液位開關(guān)生產(chǎn)廠家</p><div
