style="text-indent:25px">電子液位傳感器的使用是需要注意的。電子液位傳感器是一種測(cè)量液位的壓力傳感器。靜壓投入式液位變送器（液位計(jì)）是基于所測(cè)液體靜壓與該液體的高度成比例的原理，采用國(guó)外先進(jìn)的隔離型擴(kuò)散硅敏感元件或陶瓷電容壓力敏感傳感器，將靜壓轉(zhuǎn)換為電信號(hào)，再經(jīng)過溫度補(bǔ)償和線性修正，轉(zhuǎn)化成標(biāo)準(zhǔn)電信號(hào)（一般為4～20mA/1～5VDC）。分為兩類：一類為接觸式，包括單法蘭靜壓/雙法蘭差壓液位變送器，浮球式液位變送器，磁性液位變送器，投入式液位變送器，電動(dòng)內(nèi)浮球液位變送器，電動(dòng)浮筒液位變送器，電容式液位變送器，磁致伸縮液位變送器，侍服液位變送器等。第二類為非接觸式，分為超聲波液位變送器，雷達(dá)液位變送器等。平時(shí)對(duì)電子壓力開關(guān)的預(yù)防性維護(hù)也很重要。低流量壓力傳感器開關(guān)廠家供應(yīng)</p><p style="text-indent:25px">當(dāng)電子壓力開關(guān)用于過壓場(chǎng)合時(shí)，敏感元件將會(huì)產(chǎn)生持續(xù)形變。低流量壓力傳感器開關(guān)廠家供應(yīng)</p><p style="text-indent:25px">電子渦流流量傳感器有什么特征？電子渦流流量傳感器特征有：(1).測(cè)量渦流頻率的檢測(cè)元件，一般都設(shè)置在渦流發(fā)生器的內(nèi)部，與流體隔離，所以渦流流量傳感器可以對(duì)所有的流體進(jìn)行流量檢測(cè)。(2).在流體的通道上設(shè)置的渦流發(fā)生器是固定的，因此傳感器沒有運(yùn)動(dòng)部分，使傳感器長(zhǎng)期使用的可靠性得到保證。(3).因?yàn)樽璧K流體運(yùn)動(dòng)的只有一根渦流發(fā)生器，所以壓力損失小。(4).傳感器測(cè)量流體的溫度為-40——300℃，流體的較高壓力可達(dá)30MPa。(5).傳感器測(cè)定流速的范圍，液體較大為10m/s，氣體較大為90m/s。使用電子渦流流量傳感器時(shí)應(yīng)注意以下幾點(diǎn)：1.當(dāng)被測(cè)流體的流速偏低時(shí)，流體將產(chǎn)生不穩(wěn)定渦流，此時(shí)應(yīng)適當(dāng)減小管道的口徑以提高流速。2.當(dāng)測(cè)定附著性流體時(shí)，如果渦流發(fā)生器上附著過多的流體，將會(huì)使測(cè)量誤差增大。3.傳感器安裝時(shí)，應(yīng)設(shè)置在管道振動(dòng)小的位置，并固定在牢固可靠的支架上。低流量壓力傳感器開關(guān)廠家供應(yīng)</p></p><br
