id="ca7urdk" class="box"><p><p style="text-indent:25px">音叉式液位開關工作原理：音叉式液位開關是一種新型的液位開關。它是利用音叉振動的原理設計制作的。它是在音叉液位開關的感應棒底座，透過壓電晶片驅動音叉棒，并且由另外一壓電晶片接受振動訊號，使振動訊號得以循環(huán)，并且使感應棒產生共振。當物料與感應棒接觸時，振動訊號逐漸變小，直到停止共振時，控制電路會輸出電氣接點信號。由于感應棒感度由前端向后座依次減弱的自然原理，所以當桶槽內物料與桶周圍向上堆積，觸及感應棒底座后部或排料時，均不會產生錯誤訊號。簡單的說，音叉在壓電晶體激勵下產生機械振動，這種振動具有一定的頻率和振幅，壓差式液位控制器哪里買。當音叉被液體或固體浸沒時，壓差式液位控制器哪里買，音叉的振動頻率和振幅將發(fā)生變化，壓差式液位控制器哪里買。這個頻率變化由電子線路檢測出來并輸出一個開關量。液位開關螺牙的大小，要根據安裝環(huán)境而定。壓差式液位控制器哪里買</p><div

style="text-indent:25px">電容式液位開關是采用偵測液位變化時所引起的微小電容量（通常為PF)差值變化，并由**的ADA電容檢測芯片進行信號處理（可以輸出多種信號通訊協議，從而檢測出水位，并輸出信號到輸出端。電容式液位檢測的較大優(yōu)勢在于可以隔著任何介質檢測到容器內的水位或液體的變化，擴展了實際應用，同時有效避免了傳統(tǒng)液位檢測方式的穩(wěn)定性、可靠性差的弊端。在某些特殊領域不能檢測的問題，使用內置MCU雙核處理的ADA電容檢測芯片的電容式液位開關，就可以實現很多特殊控制功能，甚至實現更多的集成化、智能化水位檢測功能，諸如太陽能熱水器、咖啡壺等應用中掉電后的水位變化也能可靠檢測當前水位，電容式液位檢測是目前液位開關中較有優(yōu)勢的檢測方法。壓差式液位控制器哪里買液位開關安裝的時候主要看產品是屬于直裝式還是側裝式的。</p><div

style="text-indent:25px">全自動洗衣機中一般采用的液位開關就是壓力式水位開關，它裝在洗滌缸的上部，它有一根下端開口的氣管通到缸底，進水時管里的空氣被封閉在里面出不來，就形成比外界稍高的壓力。水位越高壓力越高，這樣根據壓力就可間接測知水位。而壓力的測量仍然用彈性元件，靠元件的變形帶動觸點完成通斷動作。這種測液位的方法叫做“靜壓法”，在工業(yè)中用的不少。浮球式液位開關的特點是有一個帶桿的浮球，隨著液位的變化，浮球聯動的桿隨著變化，從而控制開關的閉合。工業(yè)上很早就利用浮子測量水塔中的水位了。</p><p style="text-indent:25px">耐高溫液位浮球開關選擇型號請依照被測物之使用溫度、壓力、比重、耐酸堿等特性，選用上表所列各種規(guī)格的浮球。耐高溫浮球液位開關選擇的七個方面：1、溫度：PVDF溫度為120℃，PP為80℃，SUS304/316為200℃。 2、壓力：塑膠類浮球耐壓5kg/cm2，SUS浮球耐壓30kg/cm2。 3、粘著：應選用球大、比重小的浮球才能克服液體表面張力。 4、化性：塑膠材質適用于酸堿場所，如有溫度考慮時應選用PVDF。 5、油精：應使用金屬材質。6、比重：浮球比重SG必須小于被測液體，否則浮球浮不起來。 7、電壓：220VAC/200VDC 電流：0.7A。液位開關從形式上主要分為接觸式和非接觸式。</p><div style="width:100%;text-align:

style="text-indent:25px">液位開關安裝的時候主要看產品是屬于直裝式還是側裝式的，直裝式既可以頂裝也可以底裝，側裝式就是側面安裝，然后根據螺紋大小進行固定安裝，一般是M10的或者是根據自己的運行環(huán)境來決定大小也都是可以的，安裝其實是很簡單的。電極式液位開關是利用液體的導電性來監(jiān)測液位的高低，解釋接觸到棒極，便會導電從而輸出報警信號。電極式液位開關可多點控制，控制位置由客戶需求而定，具有突破保護功能，可有效防止突波干擾，不過電極式液位開關*適用于導電液體。電纜浮球液位開關的特點是性能穩(wěn)定可靠。壓差式液位控制器哪里買</p><p style="text-indent:25px">外測液位開關經常使用于各種液體的液體檢測。壓差式液位控制器哪里買</p><p style="text-indent:25px">液位開關注意事項：1、重錘為要求才附上之配件。2、請將電纜線直接拉到控制箱，盡量避免使用中間接頭。若不得已而有接頭時，不可將電纜線接頭浸入液體中。3、未使用的電線必須予以絕緣。浮球液位開關怎么接線呢？1.我們需要明白浮球液位開關是怎樣來實現功能的，也就是它的工作原理。浮球液位開關是由干簧管與浮球組成，通過浮球內置磁鐵吸合干簧管觸點的閉合或者斷開，從而輸出信號報警，而干簧管觸點的兩頭分別焊接一條線。2.我們需要明白浮球液位開關內部結構的接線圖，明白一個液位控制是怎么連接線路的，兩個甚至三個液位點，內部的接線是怎樣的，這樣就完全可以明白怎么去接線了！如果是需要控制雙液位，一般則是出線四條，兩條線控制一個點。當然也可以出線三條，一條公共線，另外兩條分別對應一個點，另外馳誠電子所生產的浮球開關常規(guī)出現為：黑、紅、藍、白、黃等，如果出現兩個以上動作點，則按照線材以此往上類推。壓差式液位控制器哪里買</p><p
