style="text-indent:25px">目前使用的壓力開關(guān)存在如下問題：（1）工作不可靠在對(duì)進(jìn)站壓力開關(guān)進(jìn)行校驗(yàn)時(shí)多次發(fā)現(xiàn)，當(dāng)給定壓力低于設(shè)定壓力時(shí)，壓力開關(guān)仍不動(dòng)作，當(dāng)用物體敲擊時(shí)又恢復(fù)正常。（2）誤動(dòng)作用戶反應(yīng)曾多次發(fā)生當(dāng)管線內(nèi)壓力產(chǎn)生輕微波動(dòng)時(shí)造成甩泵。致使某些壓力開關(guān)長(zhǎng)期不能投用，使輸油泵失去應(yīng)有的保護(hù)，帶來不安全因素。（3）精度低、校準(zhǔn)難在校驗(yàn)時(shí)需反復(fù)進(jìn)行試驗(yàn)才能確定設(shè)定值。（4）密閉流程解除后由于進(jìn)站壓力較低，使壓力開關(guān)無法使用。為解決現(xiàn)有壓力開關(guān)存在的這些問題，研制高可靠性、高精度和智能電子壓力開關(guān)十分必要。</p><p style="text-indent:25px">電子壓力開關(guān)如何工作？當(dāng)介質(zhì)中的壓力發(fā)生變化時(shí)，電子壓力開關(guān)用于觸發(fā)開關(guān)過程。根據(jù)壓力開關(guān)的設(shè)置，可以定義非常不同的開關(guān)點(diǎn)。電子壓力開關(guān)尤其可以用在氣體或液體介質(zhì)中。如果這些介質(zhì)之一中的壓力發(fā)生變化，則電子壓力開關(guān)會(huì)在預(yù)定的切換點(diǎn)觸發(fā)反應(yīng)。此外，電子壓力開關(guān)可以在數(shù)字顯示屏上顯示開關(guān)的各種設(shè)置。這樣可以在操作過程中更改壓力開關(guān)的設(shè)置，從而直接進(jìn)行調(diào)節(jié)。電子壓力開關(guān)通常用于機(jī)械工程中。與機(jī)械形式相比，電子壓力開關(guān)既提供數(shù)字輸出信號(hào)，又提供可自由調(diào)節(jié)的開關(guān)點(diǎn)，可靠性更高。電子壓力開關(guān)只有靈敏度高時(shí)，與被測(cè)量變化對(duì)應(yīng)的輸出信號(hào)的值才比較大。</p><div
