style="text-indent:25px">壓力變送器具有數(shù)字量接口輸出功用，可將輸出的數(shù)字信號方便地和核算機或現(xiàn)場總線等銜接。壓力變送器通常用于監(jiān)視各種行業(yè)中的儲罐液位。這些壓力測量的準確性不足會導致設備損壞，過程變更以及其他代價高昂的后果，尤其是在使用小罐和低壓范圍的情況下。市場上有許多不同類型的液位傳感器，包括浮動，超聲波和激光，可以滿足大多數(shù)應用的要求。壓力變送器在原理與結構上千差萬別，如何根據(jù)具體的測量目的、測量對象以及測量環(huán)境合理選用它，是在進行某個量的測量時首先要解決的問題。當變送器確定之后，與之相配套的測量方法和測量設備也就可以確定了。測量結果的成敗，在很大程度上取決于變送器的選用是否合理。</p><p style="text-indent:25px">通常在壓力變送器的線性范圍內，希望變送器的靈敏度越高越好。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。但要注意的壓力變送器的靈敏度高，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，要求變送器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。壓力變送器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變送器;如果被測量是多維向量，則要求變送器的交叉靈敏度越小越好。在安裝使用壓力變送器前應詳細閱讀產(chǎn)品樣本及使用說明書，安裝時壓力接口不能泄露，確保量程及接線正確。</p><div

style="text-indent:25px">壓力變送器的原理大致是：將水壓這種壓力的力學信號轉變成電流（4-20mA）這樣的電子信號壓力和電壓或電流大小成線性關系，一般是正比關系所以，變送器輸出的電壓或電流隨壓力增大而增大由此得出一個壓力和電壓或電流的關系式，壓力變送器的被測介質的兩種壓力通入高、低兩壓力室，低壓室壓力采用大氣壓或真空，作用在δ元（即敏感元件）的兩側隔離膜片上，通過元件內的填充液傳送到測量膜片兩側。壓力變送器是由測量膜片與兩側絕緣片上的電極各組成一個電容器。當兩側壓力不一致時，致使測量膜片產(chǎn)生位移，其位移量和壓力差成正比，故兩側電容量就不等，通過振蕩和解調環(huán)節(jié)，轉換成與壓力成正比的信號。不同的物理量需要不同的傳感器和相應的壓力變送器。專業(yè)壓力變送器供貨報價</p><p

style="text-indent:25px">壓力變送器是較常見的變送器，關于它的穩(wěn)定性也是至關重要的。變送器在使用一段時間后，其機能保持不變化的能力稱為穩(wěn)定性。影響壓力變送器長期穩(wěn)定性的因素除變送器本身結構外，這主要是變送器的使用環(huán)境。因此，要使變送用具有良好的穩(wěn)定性，變送器必需要有較強的環(huán)境適應能力。在選擇變送器之前應對其使用環(huán)境進行調查，并根據(jù)詳細的使用環(huán)境選擇合適的變送器，或采取適當?shù)拇胧瑴p小環(huán)境的影響。壓力變送器的穩(wěn)定性有定量指標，在超過使用期后，在使用前應重新進行標定，以確定變送器的機能是否發(fā)生變化。在某些要求變送器能長期使用而又不能等閑更換或標定的場合，所選用的變送器穩(wěn)定性要求更嚴格，要能夠經(jīng)受住長時間的考驗。壓力變送器選型</p><p
