在易燃易爆的工況場合下，考慮到現(xiàn)場的安全性，需要選擇具有防爆功能的壓力變送器。壓力變送器在防爆方式中有三種方式：控制易爆氣體、控制局限和控制yinbao源。 </p> <p> 控制易爆氣體：防爆壓力變送器工作原理是在一個密封的隔爆箱體內(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)計為隔爆標(biāo)準(zhǔn)殼體，防爆壓力變送器設(shè)計時按隔爆標(biāo)準(zhǔn)的殼體，按規(guī)范嚴(yán)格設(shè)計、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)險性氣體的。隔爆防爆辦法的設(shè)計與制造標(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。

實際上廠家對智能變送器的校準(zhǔn)也是有說明的，如ABB的變送器，對校準(zhǔn)就有:“設(shè)定量程”、“重定量程”、“微調(diào)”之分。其中“設(shè)定量程”操作主要是通過LRV.URV的數(shù)字設(shè)定來完成配置工作，而“重定量程”操作則要求將變送器連接到標(biāo)準(zhǔn)壓力源上，通過一系列指令引導(dǎo)，由變送器直接感應(yīng)實際壓力并對數(shù)值進行設(shè)置。而量程的初始、終設(shè)置直接取決于真實的壓力輸入值。但要看到盡管變送器的模擬輸出與所用的輸入值關(guān)系正確，但過程值的數(shù)字讀數(shù)顯示的數(shù)值會略有不同，這可通過微調(diào)項來進行校準(zhǔn)。由于各部分既要單獨調(diào)校又必需要聯(lián)調(diào)，因此實際校準(zhǔn)時可按以下步驟進行： </p> <p> 1．先做一次4-20mA微調(diào)，用以校正變送器內(nèi)部的D/A轉(zhuǎn)換器，由于其不涉及傳感部件，無需外部壓力信號源。 </p> <p> 2．再做一次全程微調(diào)，使4-20mA、數(shù)字讀數(shù)與實際施加的壓力信號相吻合，因此需要壓力信號源。 </p> <p> 3．做重定量程，通過調(diào)整使模擬輸出4-20mA與外加的壓力信號源相吻合，其作用與變送器外殼上的調(diào)零(Z)、調(diào)量程(R)開關(guān)的作用完全相同。 </p> <p> 壓力變送器是一種比較常用的測量儀器，可以將測壓元件受到的氣體、液體等物理參數(shù)轉(zhuǎn)變成標(biāo)準(zhǔn)的信號輸出，具有測量精細(xì)、性能穩(wěn)定、靈敏度高、操作簡便等優(yōu)點。 </p><p style="text-indent:25px">在選用壓力變送器之初，要對現(xiàn)場使用工況進行分析，根據(jù)具體使用環(huán)境選擇適合的壓力變送器，還要采取適當(dāng)?shù)拇胧瑴p少環(huán)境對壓力變送器的影響。壓力變送器穩(wěn)定性有定量指標(biāo)，在超過使用期后，需要重新進行標(biāo)定，以確保壓力變送器的性能是否發(fā)生變化。在某些要求壓力變送器能長期使用而又不能輕易更換或標(biāo)定的場合，所選用的壓力變送器穩(wěn)定性要求更嚴(yán)格，要能夠經(jīng)受住長時間的考驗。壓力變送器穩(wěn)定性有著重要的意義，選擇高穩(wěn)定性的壓力變送器是非常有必要的。在高穩(wěn)定性能這個基礎(chǔ)前提下，才能制造出具有高準(zhǔn)確度、高可靠性等能力的壓力變送器。壓力變送器穩(wěn)定性對于生產(chǎn)的正常運行以及壽命的使用都有著重要的影響。壓力變送器具有工作可靠、性能穩(wěn)定。</p><div

但是過載能力也有一個度，一般是150%的范圍內(nèi)，（星儀壓力變送器的過載能力能達(dá)到滿量程的200%或者是120MPa。）使得壓力變送器在瞬間環(huán)境影響造成的超量程中，也能免受損壞，保護芯體等元器件不被燒毀等。對我們的壓力變送器起到很好的保護作用。 </p> <p> 過載能力是每種壓力變送器都要考慮的，因為在壓力變送器的使用過程中，很有可能會出現(xiàn)測量值大于量程的情況，只有設(shè)計了過載保護的變送器才能更好的使用，也才能使用得更久。所以不管是買什么類型的壓力變送器，一定要了解它的過載能力是多少，這樣才能更好的方便使用，在未來使用過程中也不會出現(xiàn)由于過載燒壞電路的情況。 </p> <p> 在這里也要提醒大家這是個瞬間造成過載的保護措施，我們在選購壓力變送器時，還是要對量程范圍作出精確的判斷，這是壓力變送器長期穩(wěn)定工作的基礎(chǔ)。隔離變壓器的初、次級之間均用屏蔽層隔離，減少其分布電容，以提高抵抗共模干擾能力。吉林高溫型壓力變送器哪家好</p><p
