style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="水暖管道壓力變送器廠家供應(yīng),壓力變送器" src="https://tyunfile.71360.com/UploadFile/xalunqian/637328438789843750/8741677.png"></div><p> 壓力變送器問(wèn)題分析歸納： </p> <p> 1、變送器要測(cè)量什么樣的壓力：先確定系統(tǒng)中要確認(rèn)測(cè)量壓力的zui大值，一般而言，需要選擇一個(gè)具有比zui大值還要大1.5倍左右的壓力量程的變送器。這主要是在許多系統(tǒng)中，尤其是水壓測(cè)量和加工處理中，有峰值和持續(xù)不規(guī)則的上下波動(dòng)，這種瞬間的峰值能破壞壓力傳感器，持續(xù)的高壓力值或稍微超出變送器的標(biāo)定最大值會(huì)縮短傳感器的壽命，然而，由于這樣做會(huì)精度下降。于是，可以用一個(gè)緩沖器來(lái)降低壓力毛刺，但這樣會(huì)降低傳感器的響應(yīng)速度。所以在選擇變送器時(shí)，要充分考慮壓力范圍，精度與其穩(wěn)定性。 </p> <p> 2、什么樣的壓力介質(zhì)：我們要考慮的是壓力變送器所測(cè)量的介質(zhì),黏性液體、泥漿會(huì)堵上壓力接口，溶劑或有腐蝕性的物質(zhì)會(huì)不會(huì)破壞變送呂中與這些介質(zhì)直接接觸的材料。以上這些因素將決定是否選擇直接的隔離膜及直接與介質(zhì)接觸的材料。一般的壓力變送器的接觸介質(zhì)部分的材質(zhì)采用的是316不銹鋼,如果你的介質(zhì)對(duì)316不銹鋼沒(méi)有腐蝕性,那么基本上所有的壓力變送器都適合你對(duì)介質(zhì)壓力的測(cè)量.如果你的介質(zhì)對(duì)316不銹鋼有腐蝕性，那么我們就要采用化學(xué)密封起到保護(hù)壓力變送器,延長(zhǎng)了壓力變送器的壽命. </p><p> 壓力變送器的零點(diǎn)漂移: </p> <p> 壓力變送器的零點(diǎn)漂移是影響壓力變送器性能的重要指標(biāo)，應(yīng)受到大家的重視。壓力變送器的零點(diǎn)漂移是指，在大氣壓的狀態(tài)下，壓力變送器的輸出信號(hào)偏離零值上下波動(dòng)的現(xiàn)象，也稱之為零漂。 </p> <p> 壓力變送器產(chǎn)生零點(diǎn)漂移的原因很多，如電源電壓不穩(wěn)、元器件參數(shù)變值、環(huán)境溫度變化等。其中zui主要的因素是溫度的變化，因?yàn)榫w管是溫度的敏感器件，當(dāng)溫度變化時(shí)，其參數(shù)UBE、β、ICBO都將發(fā)生變化，zui終導(dǎo)致放大電路靜態(tài)工作點(diǎn)產(chǎn)生偏移。此外，在諸因素中，zui難控制的也是溫度的變化。 </p> <p> 其次壓力變送器應(yīng)用場(chǎng)所海拔高，大氣壓力較低。如果壓力壓力變送器是在平原地區(qū)進(jìn)行檢定的，這樣就會(huì)形成一個(gè)壓力差，造成壓力變送器的零點(diǎn)漂移。 </p> <p> 第三種情況，當(dāng)壓力變送器管線內(nèi)氣體濕氣較大，且有負(fù)壓時(shí)，易造成零點(diǎn)漂移。 </p> <p> 還有，如果壓力變送器中存在電路虛焊的情況。也會(huì)產(chǎn)生零點(diǎn)漂移。 </p> <p> 在壓力變送器的使用壽命期間，如果出現(xiàn)零點(diǎn)漂移的狀況，可以發(fā)回生產(chǎn)廠家，進(jìn)行重新標(biāo)定，以確保壓力變送器的測(cè)量精度。擴(kuò)散硅壓力變送器具有工作可靠、性能穩(wěn)定、安裝使用方便、體積小、重量輕、性能價(jià)格比高等特點(diǎn)。</p><div style="width:100%;text-align:

不同類型壓力變送器使用注意事項(xiàng)： </p> <p> 壓力變送器經(jīng)過(guò)長(zhǎng)期的市場(chǎng)應(yīng)用和技術(shù)研發(fā)，其成員不斷擴(kuò)大。針對(duì)一些特定使用場(chǎng)合的壓力變送器越來(lái)越多。這符合整個(gè)變送器行業(yè)發(fā)展細(xì)分化的需求。不同類型的壓力變送器不僅在特點(diǎn)上有差異，在注意事項(xiàng)上也是有一定的區(qū)別的。向大家講解一下特殊類型壓力變送器的一些使用注意事項(xiàng)。 </p> <p> 高溫型壓力變送器：在使用過(guò)程中注意不要讓介質(zhì)溫度超過(guò)壓力變送器的工作溫度。必要時(shí)，需加裝冷卻裝置（冷凝管、盤管）。 </p> <p> 防爆型壓力變送器：本安防爆型壓力變送器必須配備安全柵和本安電源才可在危險(xiǎn)場(chǎng)所使用。 </p> <p> 防水型壓力變送器：為了抵消大氣壓力，線纜內(nèi)部配有導(dǎo)氣管，產(chǎn)品接線處必須保障干燥通風(fēng)。 </p> <p> 衛(wèi)生型壓力變送器：衛(wèi)生型壓力變送器底部膜片采用的是無(wú)近壓孔、無(wú)腔平面結(jié)構(gòu)。需要注意壓力變送器的膜片非常脆弱，千萬(wàn)不能用外物碰觸！膜片變形可以導(dǎo)致測(cè)量誤差不準(zhǔn)確，如膜片損壞壓力變送器則無(wú)法使用。擴(kuò)散硅壓力變送器體積小、重量輕、安裝、調(diào)試、使用方便。水暖管道壓力變送器廠家供應(yīng)</p><p

更改智能型壓力變送器的量程范圍是我們?cè)趯?shí)際應(yīng)用中經(jīng)常會(huì)用到的一種操作。首先也是在智能型壓力變送器正常顯示時(shí)，屏幕上依次出現(xiàn)5個(gè)“0”閃爍后，等到右位閃爍時(shí)松手，按下S鍵，將智能型壓力變送器的顯示數(shù)字改成“00003”，按M鍵一次，液晶左下角顯示數(shù)字“3”。我們就進(jìn)入了智能型壓力變送器量程范圍的調(diào)節(jié)界面。這時(shí)按下S鍵一次，左側(cè)的箭頭開(kāi)始閃爍，Z鍵是位移，S鍵是更改數(shù)字。右位閃爍時(shí)，按Z鍵小數(shù)點(diǎn)全亮，按S鍵可進(jìn)行小數(shù)點(diǎn)位置的選擇。輸入完畢后按M鍵進(jìn)行數(shù)據(jù)的保存，并切換到量程上限界面。此時(shí)，智能型壓力變送器液晶顯示左下角顯示“4”，接下來(lái)就是重復(fù)以上操作，更改成想要的量程后，按M鍵進(jìn)行保存即可。需要注意的是，如果不需要調(diào)整智能型壓力變送器的量程下限，可在進(jìn)入“3”后直接按下M鍵保存并跳過(guò)，進(jìn)入“4”的界面進(jìn)行調(diào)整量程上限。水暖管道壓力變送器廠家供應(yīng)</p></p><br
