style="text-indent:25px">電子渦流流量計的結構：電子渦流流量計的基本結構，流量脊由外殼、渦流發(fā)生器和頻率檢測元件等組成。渦流發(fā)生器的下端沿樅向自由支撐，上端固定在外殼的孔內，通過密封圈再用壓板予以固定。在渦流發(fā)生器的內部裝有壓電元件，用來通過體內的應力變化檢測出渦流的頻率。渦流發(fā)生器與流體接觸部分的截面為梯形，這種形狀能使流速與渦流的頻率具有良好的線性。當渦流發(fā)生時，其內部將產生一定的應力，這種應力經壓電元件檢測后，用電路對得到的信號進行處理，從而得到跟渦流頻率對應的脈沖頻率，較終以模擬電壓的形式輸出。電子渦流頻率的檢測方法有許多種，可利用加熱體的冷卻方法來檢測渦流非生產性器周圍和內部流體流動的周期變化，也可以通過個種傳感器檢測流體振動所產生的力的周期變化。智能壓力控制器廠家供應電子壓力開關初次使用時，各個參數(shù)的設置都要按照廠商提供的說明書嚴格進行。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="鄭州高壓開關,電子" src="https://tyunfile.71360.com/UploadFile/shyouwei/637393252590643110/2919022.png"></div><p style="text-indent:25px">電子壓力開關靈敏度的選擇：電子壓力開關是一款不論是從外觀結構還是使用性能方面都比機械壓力開關優(yōu)越的智能化開關，因此，電子壓力開關的靈敏度也自然比其高，如何選擇電子壓力開關的靈敏度。通常，在開關的線性范圍內，都是希望開關的靈敏度越高越好。因為只有靈敏度高時，與被測量變化對應的輸出信號的值才比較大，有利于信號處理。但要注意的是，當電子壓力開關的靈敏度高，與被測量無關的外界噪聲也容易混入，也會被放大系統(tǒng)放大，影響測量精度。因此，要求壓力開關本身應具有較高的信噪比，盡量減少從外界引入的干擾信號。由于電子壓力開關的靈敏度是有方向性的，當被測量是單向量，而且對其方向性要求較高，則應選擇其它方向靈敏度小的開關；如果被測量是多維向量，則要求傳感器的交叉靈敏度越小越好。</p><p style="text-indent:25px">電子壓力開關保持其正常性能所能承受的較大壓力。但是當電子壓力開關用于過壓場合時，敏感元件將會產生持續(xù)形變，這時壓力設定值將變化，電子壓力開關將不能發(fā)揮其正常性能甚至可能損壞。精度：表示設備準確程度的值，包括線性度、公差、遲滯、重復性等。目前壓力開關較高精度可達到±0.5%F.S，型號為CB33。較大壓力（Max.P）：壓力范圍的較大值。滿量程（F.S）：壓力范圍較大值和較小值的差值。接斷差（死區(qū)）：是指電子壓力開關設定動作值和復位值的差值，例如當設定、值為1MPa，實際復位值為0.9MPa時，接斷差為0.1MPa。電子壓力開關正式投入運行之前，操作人員應該仔細閱讀使用說明書。</p><div

style="text-indent:25px">選擇電子壓力開關時就要注意到量程的選擇和電子壓力開關的工作環(huán)境。量程的選擇一定要符合工作條件；工作環(huán)境如果是震動、沖擊的場所，需要加裝固定裝置固定電子壓力開關，如果是潮濕環(huán)境需要將入口點密封起來防止?jié)駳獾倪M入。操作時，電子壓力開關可允許在啟動和測試時達到大壓力和高溫度，但是如果是持續(xù)不斷的工作，則需嚴格按照范圍內的數(shù)值操作。而且電子壓力開關在作業(yè)時，要有專員時刻觀察壓力開關的元件，檢查是否有設定點漂移的情況，防止意外的發(fā)生。平時對電子壓力開關的預防性維護也很重要，不經常使用電子壓力開關時，需要一個備用件，防止電子壓力開關長時間不工作引起的元件毀壞，造成隱患。電子壓力開關一定要嚴格安裝范圍制定的數(shù)據(jù)來操作。智能壓力控制器廠家供應</p><p
