style="text-indent:25px">電子開關的使用是需要注意的。電子開關的信號自動分段技術是經過對現(xiàn)場信號多次模型分析，采用信號自動分段技術與模型識別技術從而能有效的克服壓力波動等各種干擾，提高壓力開關的可靠性。信號自動分段方法的基本原理是選用一個固定的窗選取平穩(wěn)運行的信號作為參考段，不斷與當前信號作比較，非平穩(wěn)性（如上站停泵引起的信號特性的變化）可以由不同段之間的過程統(tǒng)計特性和頻譜性的改變顯示出來。一般根據(jù)幾種判據(jù)，當判據(jù)大于一定的閾值或當前段低于設定值時，就認為信號進入了另一段（異常段）。</p><p style="text-indent:25px">電子壓力開關如何工作？當介質中的壓力發(fā)生變化時，電子壓力開關用于觸發(fā)開關過程。根據(jù)壓力開關的設置，可以定義非常不同的開關點。電子壓力開關尤其可以用在氣體或液體介質中。如果這些介質之一中的壓力發(fā)生變化，則電子壓力開關會在預定的切換點觸發(fā)反應。此外，電子壓力開關可以在數(shù)字顯示屏上顯示開關的各種設置。這樣可以在操作過程中更改壓力開關的設置，從而直接進行調節(jié)。電子壓力開關通常用于機械工程中。與機械形式相比，電子壓力開關既提供數(shù)字輸出信號，又提供可自由調節(jié)的開關點，可靠性更高。電子壓力開關的靈敏度也是比較高的。</p><div
