id="dskrjac" class="box"><p><p style="text-indent:25px">壓力變送器主要優(yōu)點：1、壓力變送器具有工作可靠、性能穩(wěn)定等特點；2、**V/I集成電路，外圍器件少，可靠性高，維護簡單、輕松，體積小、重量輕，安裝調(diào)試極為方便；3、鋁合金壓鑄外殼，三端隔離，靜電噴塑保護層，堅固耐用；4、4-20mADC二線制信號傳送，抗干擾能力強，傳輸距離遠；5、LED，杭州傳感器現(xiàn)價、LCD、指針三種指示表頭，現(xiàn)場讀數(shù)十分方便。可用于測量粘稠、結(jié)晶和腐蝕性介質(zhì)；6、高準確度，高穩(wěn)定性。除進口原裝傳感器已用激光修正外，對整機在使用溫度范圍內(nèi)的綜合性溫度漂移、非線性進行精細補償。常見的變送器有普通壓力變送器、差壓變送器，杭州傳感器現(xiàn)價，杭州傳感器現(xiàn)價、單法蘭變送器、雙法蘭變送器、插入式法蘭變送器等。杭州傳感器現(xiàn)價</p><div

style="text-indent:25px">差壓變送器實際的工藝情況：1）考慮被測對象是屬于哪一類設(shè)備。如槽、罐類，槽的容積較小，測量范圍不會太大，罐的容積較大，測量范圍可能較大；2）要看介質(zhì)的物化性質(zhì)及潔凈程度，開始選常規(guī)的差壓式變送器及浮筒式液位變送器，還要對接觸介質(zhì)部分的材質(zhì)進行選擇；3）對有些懸浮物、泡沫等介質(zhì)可用單法蘭式差壓變送器。有些易析出、易結(jié)晶的用插入式雙法蘭式差壓變送器；4）對高黏度的介質(zhì)的液位及高壓設(shè)備的液位，由于設(shè)備無法開孔，可選用放射液位計來測量；5）除了測量方法上和技術(shù)上問題外，還有儀表投資問題。杭州傳感器現(xiàn)價壓力變送器也稱差變送器，主要由測壓元件傳感器、模塊電路、顯示表頭、表殼和過程連接件等組成。</p><div

style="text-indent:25px">變送器超時工作后需要保持穩(wěn)定度：大部分變送器在經(jīng)過超時工作后會產(chǎn)生“漂移”，因此很有必要在購買前了解變送器的穩(wěn)定度，這種預(yù)先的工作能減少將來使用中會出現(xiàn)的種種麻煩。變送器的封裝：變送器的封裝，尤其往往容易忽略是它的機架，然而這一點在以后使用中會逐漸暴露出其缺點。在選購傳送器傳一定要考慮到將來變送器的工作環(huán)境，濕度如何，怎樣安裝變送器，會不會有強烈的撞擊或振動等。在變送器與其它電子設(shè)備間采用怎樣的連接：是否需要采用短距離連接，若是采用長距離連接，是否需要采用一個連接器。</p><p style="text-indent:25px">變送器常見故障：（1）安裝時應(yīng)使變送器的壓力敏感件軸向垂直于重力方向，如果安裝條件限制，則應(yīng)安裝固定后調(diào)整變送器零位到標準值。（2）殘存的壓力釋放不出，因此傳感器零位又下不來。排除此原因的較好的方法是將傳感器卸下，直接察看零位是否正常，如果正常更換密封圈再試。（3）加壓變送器輸出不變化，再加壓變送器輸出突然變化，泄壓變送器零位回不去。產(chǎn)生此現(xiàn)象的原因極有可能是壓力傳感器密封圈引起的。（4）是否符合供電要求；電源與變送器及負載設(shè)備之間有無接線錯誤。如果變送器接線端子上無電壓或極性接反均可造成變送器無電壓信號輸出。差壓變送器是一種典型的自平衡檢測儀表，它利用負反饋的工作原理克服元件材料、加工工藝等不利因素的影響。</p><div

style="text-indent:25px">隔離型壓力變送器選用比較好的是選用螺紋連接形式的，這樣既節(jié)約資金安裝又方便。對于普通壓力和差壓變送器選型，也要考慮被測介質(zhì)的腐蝕性問題，但使用的介質(zhì)溫度可以不考慮，因為普通型壓變是引壓到表內(nèi)，長期工作溫度為常溫，但普通型使用的維護量要比隔離型大。首先是保溫問題，在北方冬季零下，導(dǎo)壓管會結(jié)冰，變送器無法工作甚至損壞，這就需要增加伴熱和保溫箱等。從經(jīng)濟角度上來講，選用變送器時，只要不是易結(jié)晶介質(zhì)都可以采用普通型變送器，而且對于低壓易結(jié)晶介質(zhì)也可以加吹掃介質(zhì)來間接測量（只要工藝允許用吹掃液或氣），應(yīng)用普通型變送器就是要求維護人員多進行定時檢查，包括各種導(dǎo)壓管是否泄漏、吹掃介質(zhì)是否正常、保溫是否良好等，只要維護好，大量使用普通型變送器一次性投資會節(jié)約很多。銻電極酸度變送器中的固體模塊電路由兩大部分組成。杭州傳感器現(xiàn)價</p><p
