<p> 控制易爆氣體：防爆壓力變送器工作原理是在一個(gè)密封的隔爆箱體內(nèi)，充滿不含易爆氣體的潔凈氣體或惰性氣體，并保持箱內(nèi)氣壓略高于箱外氣壓，將壓力變送器安裝在箱內(nèi)。 </p> <p> 控制局限：這種形式的工作原理是將防爆壓力變送器外殼設(shè)計(jì)為隔爆標(biāo)準(zhǔn)殼體，防爆壓力變送器設(shè)計(jì)時(shí)按隔爆標(biāo)準(zhǔn)的殼體，按規(guī)范嚴(yán)格設(shè)計(jì)、制造和裝配一切的管理辦法執(zhí)行工藝，使在殼體內(nèi)發(fā)作的不致于激發(fā)殼體外風(fēng)險(xiǎn)性氣體的。隔爆防爆辦法的設(shè)計(jì)與制造標(biāo)準(zhǔn)極端嚴(yán)厲，并且裝配、接線和維修的操作規(guī)程也十分嚴(yán)厲。該辦法決定了隔爆的電氣設(shè)備、儀表往往十分嚴(yán)格，操作須斷電等。 </p> <p> 控制yinbao源：此種方法的工作原理是應(yīng)用安全柵進(jìn)行隔離接線從防爆壓力變送器在用電配電進(jìn)行處理，將供應(yīng)給現(xiàn)場(chǎng)防爆壓力變送器的電能量限制在既不能發(fā)生足以yinbao的火花，又能發(fā)生足以yinbao的儀表外表溫升的平安局限內(nèi)。依照國(guó)際規(guī)范和我國(guó)的國(guó)度規(guī)范，當(dāng)安全柵平安區(qū)一側(cè)所接設(shè)備發(fā)作任何以障時(shí)，實(shí)質(zhì)安全防爆辦法確保風(fēng)險(xiǎn)現(xiàn)場(chǎng)的防爆安全。防爆壓力變送器價(jià)格查詢壓力變送器的靈敏度高，與被測(cè)量無關(guān)的外界噪聲也容易混入，也會(huì)被放大系統(tǒng)放大，影響測(cè)量精度。</p><div

壓力變送器采用進(jìn)口硅壓阻式隔離膜充油芯體作為信號(hào)測(cè)量元件，產(chǎn)品整體性能高，產(chǎn)品經(jīng)過元器件、半成品、成品嚴(yán)格測(cè)試，長(zhǎng)期老化等工藝篩選，長(zhǎng)期穩(wěn)定性好、抗干擾能力強(qiáng)，能長(zhǎng)期安全可靠地在環(huán)境相對(duì)惡劣的條件下工作。 </p> <p> 產(chǎn)品特點(diǎn): </p> <p> 測(cè)量范圍廣，鋁鑄防爆殼體，壓力接口形式多樣;輸出信號(hào)形式多樣，現(xiàn)場(chǎng)可調(diào)可顯示;多重防護(hù)，抗電磁干擾能力強(qiáng);表壓、絕壓和密封參考?jí)? </p> <p> 產(chǎn)品應(yīng)用:對(duì)316L不銹鋼無腐蝕的氣體、液體壓力測(cè)量。應(yīng)用于石油化工行業(yè)、電力、冶金、鋼鐵等工業(yè)現(xiàn)場(chǎng)的壓力測(cè)控。 </p><p> 擴(kuò)散硅壓力變送器工作原理: </p> <p> 擴(kuò)散硅壓力變送器是在單晶硅片上擴(kuò)散一個(gè)惠斯通電橋，當(dāng)被測(cè)介質(zhì)的壓力直接作用于變送器的擴(kuò)散硅膜片上，使得變送器的膜片產(chǎn)生與介質(zhì)壓力成正比的微小位移。正常工作狀態(tài)下，膜片較大位移不大于0.025毫米，這時(shí)擴(kuò)散硅壓力變送器的橋壁電阻值發(fā)生變化，會(huì)產(chǎn)生一個(gè)差動(dòng)電壓信號(hào)，這一信號(hào)經(jīng)過**放大器，將量程相對(duì)應(yīng)的信號(hào)轉(zhuǎn)換輸出一個(gè)標(biāo)準(zhǔn)的模擬信號(hào)或數(shù)字信號(hào)。 </p> <p> 硅的電阻率對(duì)壓力有較高的敏感度，現(xiàn)在普遍使用硅材料作壓力變送器，也就是擴(kuò)散硅壓力變送器。擴(kuò)散硅是制造壓力變送器的中心部件，被封裝在316L不銹鋼的材料之中，外加施壓通過不銹鋼膜片、內(nèi)部密封的硅油傳遞到敏感的芯片上，擴(kuò)散硅敏感元件不直接接觸被測(cè)介質(zhì)，形成壓力測(cè)量的全固態(tài)結(jié)構(gòu)，使得擴(kuò)散硅壓力變送器能夠應(yīng)用更多的工況場(chǎng)合。 </p> <p> 擴(kuò)散硅壓力變送器作為一種高性能的壓力測(cè)量產(chǎn)品，可以很方便地進(jìn)行放大處理，裝配成標(biāo)準(zhǔn)信號(hào)輸出。擴(kuò)散硅壓力變送器廣泛應(yīng)用于石油、化工、冶金、電力、航空、醫(yī)療設(shè)備、汽車等行業(yè)的過程控制。擴(kuò)散硅壓力芯體外加氟橡膠O型圈進(jìn)行可靠密封。擴(kuò)散硅壓力變送器具有結(jié)構(gòu)小巧、安裝方便，抗干擾強(qiáng)、精度高、穩(wěn)定性好、響應(yīng)速度快、耐沖擊等特點(diǎn)。壓力變送器把壓力信號(hào)傳到電子設(shè)備，進(jìn)而在計(jì)算機(jī)顯示壓力。</p><div

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. 擴(kuò)散硅壓力變送器體積小、重量輕、安裝、調(diào)試、使用方便。防爆壓力變送器價(jià)格查詢</p><p style="text-indent:25px">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)。防爆壓力變送器價(jià)格查詢</p><p> 水壓變送器介紹： </p> <p> 通用型壓力變送器采用壓阻式壓力傳感器。壓阻式傳感器是壓力式傳感器的一種。壓阻式壓力傳感器又稱擴(kuò)散硅壓力傳感器。壓阻式壓力變送器,傳感器信號(hào)經(jīng)過信號(hào)處理電路后轉(zhuǎn)換為標(biāo)準(zhǔn)信號(hào)輸出，產(chǎn)品經(jīng)過了長(zhǎng)期老化及穩(wěn)定性考核等工藝嚴(yán)格篩選，性能穩(wěn)定可靠。應(yīng)用于環(huán)境比較惡劣的露天現(xiàn)場(chǎng)，同時(shí)要求能夠現(xiàn)場(chǎng)觀測(cè)壓力顯示、需要零點(diǎn)遷移和量程調(diào)節(jié)的場(chǎng)合。應(yīng)用領(lǐng)域：適用于石油、化工、冶金、電力、輕工、紡織、建材、水文地質(zhì)、食品、醫(yī)藥、環(huán)境控制等行業(yè)的過程控制和壓力測(cè)量。 </p> <p> 水壓變送器擴(kuò)散硅跟電容變送器的對(duì)比:根本區(qū)別在于基礎(chǔ)檢出信號(hào)不同。以及相應(yīng)的電路和構(gòu)造不同;電容式變送器的基礎(chǔ)信號(hào)是電容量；擴(kuò)散硅變送器的基礎(chǔ)信號(hào)是電阻值;電容式在壓力作用下敏感元件的膜片發(fā)生位移，導(dǎo)致膜片與相鄰電極構(gòu)成的電容量發(fā)生變化而檢出壓力；擴(kuò)散硅在壓力作用下敏感元件的膜片發(fā)生位移，產(chǎn)生的力作用在擴(kuò)散硅材料商，使擴(kuò)散硅的阻值變化而檢出壓力;電容式利用的是物理性質(zhì)，所以主要受制造水平的限制；擴(kuò)散硅利用的是材料的物理性質(zhì)，所以受材料影響較大;擴(kuò)散硅在體積、價(jià)格上有優(yōu)勢(shì)；但受擴(kuò)散硅材料的穩(wěn)定性影響，壽命的精度較差。防爆壓力變送器價(jià)格查詢</p></p><br
