style="text-indent:25px">電子開關與同類產(chǎn)品的比較：電子壓力開關目前與普通的壓力開關相比有如下特點：（1）采用了模型識別技術(shù)克服了現(xiàn)有壓力開關的壓力瞬間超低時，壓力開關動作造成不正常甩泵。（2）增加了流程選擇開關，旁接罐流程、密閉流程可設置不同的閾值，旁接罐流程設置的閾值可適當降低，從而解決了旁接罐流程壓力開關不能投用的問題。（3）增設了校準按鈕，在對智能電子壓力開關校驗時只要按下“校準按鈕”，微電腦就會自動記憶當前壓力值，并把該值作為“智能電子壓力開關”設定值，從而實現(xiàn)壓力開關的智能校驗。電子壓力開關的內(nèi)部材質(zhì)材質(zhì)直接決定了壓力開關的使用環(huán)境的溫度，溫度如果使用不當，會使壓力開關不動作。</p><div

style="text-indent:25px">電子開關的信號自動分段技術(shù)是經(jīng)過對現(xiàn)場信號多次模型分析，采用信號自動分段技術(shù)與模型識別技術(shù)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）。平時對電子壓力開關的預防性維護也很重要。電子數(shù)顯壓力開關</p><p

style="text-indent:25px">電子渦流流量傳感器的每個擋板式流量傳感器都配有與水環(huán)熱泵機組水管相同的管件，現(xiàn)場只需連接上水管即可，不需對擋片做任何改變，另外擋板式水流開關的承壓大于25bar，在對水流量要求不高的水環(huán)熱泵機組是一個低成本的水流開關。經(jīng)過在水環(huán)/地源熱泵機組上使用的反饋來看，壓差開關能有效判斷水環(huán)熱泵機組現(xiàn)場安裝的水管路的問題，能徹底避免水流量少造成換熱器凍壞的情況，流量傳感器也可以保護由于水過濾器堵塞造成的水流量下降時換熱器凍壞的情況，另外水管路壓差開關沒有靶流開關疲勞破壞的風險。尤其在水管路有少量空氣時，流量傳感器工作非常穩(wěn)定，不會出現(xiàn)類似靶流開關的漂浮情況，經(jīng)過多年使用的反饋未發(fā)現(xiàn)壓差開關本身有故障的情況。安徽電子開關</p></p><br
