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。寧夏防爆壓力變送器推薦不用的變送器要把引壓管放掉冷凝水，防止不用的冷凝水溫度下降造成水冷凝產(chǎn)生負(fù)壓吸力引起負(fù)壓損壞膜盒。</p><div

在**測(cè)試、化工爆破、土木及流體力學(xué)實(shí)驗(yàn)中，需要敏感元件將現(xiàn)場(chǎng)的“力”以及“力”從零到比較大的變化過程不失真的記錄下來，這就要求壓力傳感器有足夠高的響應(yīng)頻率。高頻壓力傳感器利用半導(dǎo)體硅的楊氏彈性模量和良好的力學(xué)特性做成，從而使傳感器具有很高的固有頻率，結(jié)合SMI先進(jìn)的結(jié)構(gòu)設(shè)計(jì)，減小了頻率損耗和應(yīng)力，從而獲得很高的響應(yīng)頻率和穩(wěn)定的信號(hào)，調(diào)理電路經(jīng)過寬帶放大、一體化溫度補(bǔ)償，穩(wěn)定性好、可靠性高、對(duì)敏感元件的帶寬無影響，是瞬間壓力測(cè)量的理想產(chǎn)品。

怎樣避免壓力變送器使用中的誤差:因?yàn)閴毫ψ兯推魇褂眠^程中的誤操作，會(huì)使得壓力變送器的測(cè)量結(jié)果產(chǎn)生誤差。壓力變送器測(cè)量誤差的大小，終將影響到整個(gè)測(cè)控系統(tǒng)的性能。為大家總結(jié)整理了壓力變送器可能造成誤差的原因，并教大家一些減少和避免誤差的有效方法。 </p> <p> 造成誤差的原因：原因一：液體管路中有氣體;原因二：磨損損失;原因三：泄露;原因四：氣體管路中存有液體;原因五：兩邊導(dǎo)壓管之間因溫差引的密度不同. </p> <p> 減少誤差的方法：方法一：壓力變送器使用現(xiàn)場(chǎng)的導(dǎo)壓管盡可能短些;方法二：當(dāng)壓力變送器測(cè)量液體或蒸汽時(shí)，導(dǎo)壓管向上流連接到工藝管道，其斜度應(yīng)不小于1/12;方法三：壓力變送器對(duì)于氣體測(cè)量時(shí)，導(dǎo)壓管向下連接到工藝管道，其斜度應(yīng)不小于1/12;方法四：液體導(dǎo)壓管道的布設(shè)要避免中間出現(xiàn)高點(diǎn)，氣體導(dǎo)壓管的布設(shè)要避免中間出現(xiàn)低點(diǎn);方法五：兩導(dǎo)壓管之間應(yīng)保持相同溫度;方法六：為避免磨擦影響，導(dǎo)壓管的口徑應(yīng)足夠大;方法七：充滿液體的導(dǎo)壓管中應(yīng)無氣體存在;方法八：當(dāng)使用隔離液時(shí)，兩邊導(dǎo)壓管的液體要相同;方法九：采用潔凈劑時(shí)，潔凈劑連接處應(yīng)靠近工藝管道取壓口，潔凈劑所經(jīng)過的管路，其長(zhǎng)度和口徑應(yīng)相同，應(yīng)避免潔凈劑通過壓力變送器。不管什么型號(hào)的差壓變送器，其正、負(fù)壓室都有排氣、排液閥或旋塞;這為我們現(xiàn)場(chǎng)校準(zhǔn)差壓變送器提供了方便。</p><div

壓力變送器在使用過程中會(huì)遇到輸出電流波動(dòng)或不穩(wěn)定的狀況。我們要如何進(jìn)行這種故障的維修呢？我們就結(jié)合壓力變送器輸出電流波動(dòng)或不穩(wěn)定的現(xiàn)象，來對(duì)壓力變送器進(jìn)行分析處理。壓力變送器輸出電流波動(dòng)，在DCS顯示曲線上是可以明顯地看到的。在進(jìn)行故障排查的時(shí)候，可以先將控制系統(tǒng)切換至手動(dòng)觀察波動(dòng)情況。如果測(cè)量曲線波動(dòng)仍很頻繁,應(yīng)該是工藝的原因。如果波動(dòng)減少了，則可能是壓力變送器的原因或PID參數(shù)整定不當(dāng)引起。壓力變送器輸出電流波動(dòng)很明顯，顯示時(shí)有時(shí)無，時(shí)高時(shí)低時(shí)，應(yīng)重點(diǎn)檢查測(cè)量回路的連接情況。認(rèn)真排查接線端子的螺釘有沒有松動(dòng)、氧化、腐蝕而造成接觸不良。如果懷疑壓力變送器有問題，可以在有流量或壓力的狀態(tài)下，把三閥組或取樣閥關(guān)閉,使變送器保持一個(gè)固定的差壓或壓力，觀察變送器的輸出電流是否穩(wěn)定,如果電流仍不穩(wěn)定則變送器有故障或有干擾。 </p> <p> <br /> </p> <p> <br /> 壓力變送器引壓管內(nèi)是否有沙子、雜質(zhì)等堵塞管道，有雜質(zhì)時(shí)會(huì)使測(cè)量精度受到影響。寧夏防爆壓力變送器推薦</p><p
