style="text-indent:25px">音叉式液位開關(guān)工作原理：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，使振動(dòng)訊號得以循環(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)訊號逐漸變小，直到停止共振時(shí)，控制電路會輸出電氣接點(diǎn)信號。由于感應(yīng)棒感度由前端向后座依次減弱的自然原理，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)，均不會產(chǎn)生錯(cuò)誤訊號。簡單的說，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出來并輸出一個(gè)開關(guān)量。</p><p style="text-indent:25px">超聲波液位開關(guān)的優(yōu)勢體現(xiàn)：1、從測量方式上：測量方式不同與其他液位計(jì)，磁翻板液位計(jì)其特點(diǎn)是無需在容器上開孔，利用微振動(dòng)分析原理，在容器外部就能夠不間斷地測出液面的精確高度。2、從安全性能以及成本控制上看：是真正的非接觸式測量儀表，傳感器安裝在容器底部和側(cè)壁，快速、可靠和高精度容器容積測量，易于安裝，無需破壞容器，在安裝的過程中無需設(shè)備停車，無可移動(dòng)部件，幾乎不需要維護(hù)。超聲波液位開關(guān)被測容器的材質(zhì)可以是各類金屬、非金屬等硬質(zhì)料。其發(fā)射信號可穿透的罐壁厚度達(dá)70mm。這種測量技術(shù)不受介質(zhì)密度、介電常數(shù)、導(dǎo)電性、反射系數(shù)、壓力、溫度、沉淀等因素的影響。特別是在有毒的、強(qiáng)腐蝕的、易燃易爆等危險(xiǎn)品液體的測量中具有不可替代性。對于使用環(huán)境是有一定要求的，其中：主機(jī)使用環(huán)境溫度：-20℃～+70℃超聲波探頭使用環(huán)境溫度：-50℃～+100℃濕度：15%～100%RH注：若溫度低于-20℃時(shí)，建議給主機(jī)增加保溫措施。非接觸式液位開關(guān)安裝時(shí)不需要考慮電源位置，增加了使用的靈活性。</p><div
