style="text-indent:25px">隨著國內(nèi)工業(yè)自動化改造進程的逐漸加快,壓力變送器應用范圍的不斷拓寬,工業(yè)用戶對壓力變送器的穩(wěn)定性尤為關(guān)注。產(chǎn)品的質(zhì)量和企業(yè)生產(chǎn)效率對企業(yè)而言是非常重要的,因而對檢測環(huán)節(jié)的壓力變送器的要求也很高。早期光能穩(wěn)定運行6～12個月的壓力變送器已經(jīng)遠遠不能達到客戶的需要,而現(xiàn)在要求變送器必須達到18個月以上。而且工業(yè)用戶對壓力變送器的故障率也提出了嚴格的要求。在一些重要作業(yè)環(huán)境中,壓力變送器的故障率直接影響著用戶生產(chǎn)的安全性。在現(xiàn)場應用中,隨著自動化工程項目規(guī)模的逐漸擴大,對壓力變送器現(xiàn)場安裝的難易程度也提出了更高的要求,在保證儀表穩(wěn)定運行的前提下,要求儀表的安裝更加便捷。近些年,產(chǎn)品市場競爭不斷加劇,對產(chǎn)品質(zhì)量提出了新的要求,進而導致工業(yè)用戶對壓力檢測的精度也不斷提高。由原來的0.25～0.5級,已經(jīng)提升到0.1～0.075級。隨著工業(yè)網(wǎng)絡控制和通信的不斷發(fā)展,對于壓力變送器,除了要保證原有測量指標外,還必須滿足網(wǎng)絡數(shù)據(jù)通信的要求,因此,壓力變送器中的通信協(xié)議也成為工業(yè)用戶要求的指標之一。鹽城無線壓力變送器壓力變送器信號不穩(wěn)原因：傳感器本身振動很厲害。</p><div

style="text-indent:25px">壓力變送器選擇恰當?shù)奈恢茫寒攭毫ψ兯推鞯陌惭b位置太靠近生產(chǎn)線的上游時，未熔融的物料可能會磨損傳感器的頂部；如果傳感器被安裝在太靠后的位置，在傳感器和螺桿行程之間可能會產(chǎn)生熔融物料的停滯區(qū)，熔料在那里有可能產(chǎn)生降解，壓力信號也可能傳遞失真；如果傳感器過于深入機筒，螺桿有可能在旋轉(zhuǎn)過程中觸碰到傳感器的頂部而造成其損壞。一般來說，傳感器可以位于濾網(wǎng)前面的機筒上、熔體泵的前后或者模具中。仔細清潔；在使用鋼絲刷或者特殊化合物對擠出機機筒進行清潔前，應該將所有的傳感器都拆卸下來。因為這兩種清潔方式都可能會造成傳感器的震動膜受損。當機筒被加熱時，也應該將傳感器拆卸下來并使用不會產(chǎn)生磨損的軟布來擦拭其頂部，同時傳感器的孔洞也需要用清潔的鉆孔機和導套清理干凈。</p><p style="text-indent:25px">在使用壓力變送器的時候應該避免哪些問題？當我們在接線的時候，是將電纜穿過防水街頭或者是繞性管并擰緊密封螺帽，這樣能夠防止雨水通過電纜進入到壓力變送器中，損壞壓力變送器。當我們在測量氣體壓力的時候，壓力變送器的取壓口應該在流程管道的頂端，并且變送器也應該安裝在流程管道的上部，這樣能夠更好的讓積累的液體注入到流程管道之中。后，如果我們是用壓力變送器測量液體的壓力的話，壓力變送器的取壓口應該開在流程管道的側(cè)面，這樣能夠避免沉淀積渣。并且，壓力變送器在使用電壓的時候是不能夠使用高于36v的電壓的，否者是會出現(xiàn)損壞的情況的。智能型壓力變送器：準確度高，使用與維護方便。</p><div
