</p> <p> 壓力變送器的常規(guī)供電電壓為12～36V DC,采用此范圍的供電電壓可以有效的避免因電壓過(guò)高造成損壞，選擇此范圍的供電電壓也比較符合現(xiàn)在主流設(shè)備，方便壓力變送器與其它設(shè)備系統(tǒng)進(jìn)行對(duì)接，LED顯示壓力變送器分類(lèi)、組合使用。習(xí)慣上24V

壓力變送器的精度。在質(zhì)量上分析，壓力變送器的精度是zui重要的技術(shù)參數(shù)。壓力變送器精度關(guān)系到整個(gè)測(cè)量系統(tǒng)的zui終結(jié)果。儀表的精度簡(jiǎn)言之就是儀表測(cè)量值接近真值的準(zhǔn)確程度，通常用相對(duì)百分誤差（也稱(chēng)相對(duì)折合誤差）表示。按儀表工業(yè)規(guī)定，儀表的精確度劃分成若干等級(jí)，簡(jiǎn)稱(chēng)精度等級(jí)。精度等級(jí)的數(shù)字越小，精度越高。我們可以從三個(gè)方面理解壓力變送器精度的概念：1、精度表示測(cè)量結(jié)果與真值之間的一致程度，它反映測(cè)量結(jié)果中系統(tǒng)誤差與隨機(jī)誤差的綜合。其定量特征可用測(cè)量的不確定度(或極限誤差)來(lái)表示。2、精度表示在一定條件下進(jìn)行多次測(cè)量時(shí)，所得測(cè)量結(jié)果彼此之間符合的程度，它反映測(cè)量結(jié)果中隨機(jī)誤差的影響程度。3、精度表示測(cè)量結(jié)果中系統(tǒng)誤差大小的程度，反映了規(guī)定條件下，測(cè)量結(jié)果中所有系統(tǒng)誤差的綜合。在價(jià)格上，壓力變送器的精度越高，其價(jià)格也越昂貴。在實(shí)際使用過(guò)程中，如果測(cè)量目的是定性分析，不必要選用juedui量值精度高的壓力變送器；如果是為了定量分析，必須獲得精確的測(cè)量值，就需選用精度等級(jí)能滿(mǎn)足要求的壓力變送器。立柱式壓力變送器變送器的輸出信號(hào)傳輸?shù)街锌厥疫M(jìn)行壓力指示、記錄或控制。</p><div

一般壓力變送器的適用于測(cè)量氣體、液體等與變送器材質(zhì)兼容的介質(zhì)。壓力變送器是如何測(cè)量氣體介質(zhì)的。壓力變送器對(duì)于氣體可進(jìn)行絕壓、負(fù)壓和表壓的測(cè)量。氣體的壓力簡(jiǎn)單的說(shuō)就是氣體本身對(duì)于容器壁的壓力。很多物理和化學(xué)特性都與壓力有關(guān)，比如氣體的沸點(diǎn)、熔點(diǎn)和蒸氣壓，熱力學(xué)，動(dòng)力學(xué)等。所以說(shuō)壓力變送器對(duì)于壓力氣體的測(cè)量是具有重要意義的。在壓力變送器的單晶硅片上擴(kuò)散一個(gè)惠斯通電橋，當(dāng)管道或者容器內(nèi)的氣體對(duì)壓力變送器進(jìn)行施壓，使得壓力變送器橋壁電阻值發(fā)生變化（壓阻效應(yīng)），這樣就產(chǎn)生一個(gè)差動(dòng)電壓信號(hào)，這個(gè)信號(hào)在經(jīng)過(guò)**的放大器，終將測(cè)得的量程相對(duì)應(yīng)的信號(hào)轉(zhuǎn)化成標(biāo)準(zhǔn)的電流、電壓或者數(shù)字信號(hào)。這就是壓力變送器如何對(duì)氣體進(jìn)行測(cè)量的一個(gè)過(guò)程。壓力變送器對(duì)于氣體的測(cè)量尤其是蒸汽或其他高溫氣體進(jìn)行測(cè)量的時(shí)候，需要注意不要讓高溫氣體的溫度超過(guò)壓力變送器的工作溫度范圍，必要時(shí)，為壓力變送器添加冷卻裝置是個(gè)不錯(cuò)的選擇。 </p> <p> <br /> </p><p> 變送器需要多大的精度：決定精度的有，非線(xiàn)性，遲滯性，機(jī)電商務(wù)網(wǎng) 非重復(fù)性，溫度、零點(diǎn)偏置刻度，溫度的影響。但主要由非線(xiàn)性，遲滯性，非重復(fù)性，精度越高，價(jià)格也就越高。每一種電子式的測(cè)量計(jì)都會(huì)有精度誤差的,但是由于各個(gè)國(guó)家所標(biāo)的精度等級(jí)是不一樣的. </p> <p> 變送器的溫度范圍：通常一個(gè)變送器會(huì)標(biāo)定兩個(gè)溫度范圍，即正常操作的溫度范圍和溫度可補(bǔ)償?shù)姆秶?emsp;正常操作溫度范圍是指變送器在工作狀態(tài)下不被破壞的時(shí)候的溫度范圍，在超出溫度補(bǔ)范圍時(shí)，可能會(huì)達(dá)不到其應(yīng)用的性能指標(biāo)。溫度補(bǔ)償范圍是一個(gè)比操作溫度范圍小的典型范圍。在這個(gè)范圍內(nèi)工作，變送器肯定會(huì)達(dá)到其應(yīng)有的性能指標(biāo)。溫度變從兩方面影響著其輸出，一是零點(diǎn)漂移；二是影響滿(mǎn)量程輸出。如：滿(mǎn)量程的+/-X%/℃，讀數(shù)的+/-X%/℃，在超出溫度范圍時(shí)滿(mǎn)量程的+/-X%，在溫度補(bǔ)償范圍內(nèi)時(shí)讀數(shù)的+/-X%，如果沒(méi)有這些參數(shù)，會(huì)導(dǎo)至在使用中的不確定性。變送器輸出的變化到度是由壓力變化引起的，還是由溫度變化引起的。溫度影響是了解如何使用變送器時(shí)zui復(fù)雜的一部分。大氣壓力變送器指的是，能將大氣重量轉(zhuǎn)換為電信號(hào)進(jìn)行輸出，并為我們提供查看數(shù)據(jù)的儀器儀表。</p><div

第一步：差壓變送器量程；不管我們選擇什么樣的差壓變送器，先要確認(rèn)的就是差壓量程、單端靜壓。因?yàn)榱砍痰牟町?，直接影響差壓變送器選擇的類(lèi)型不同。 </p> <p> 第二步：差壓變送器所處環(huán)境；影響差壓變送器的環(huán)境因素有兩個(gè)，一是環(huán)境溫度和濕度，二是現(xiàn)場(chǎng)干擾情況。差壓變送器對(duì)溫度和濕度都是有嚴(yán)格要求的。像是室內(nèi)環(huán)境中應(yīng)用的差壓變送器，選擇變送器環(huán)境溫度在-40～85℃之間，環(huán)境濕度在0%～95%RH之間即可。在戶(hù)外使用或超過(guò)上述范圍、現(xiàn)場(chǎng)有雨水或露水淋濺時(shí)，就要考慮用價(jià)格更貴的3051型差壓變送器。 </p> <p> 第三步：差壓變送器被測(cè)介質(zhì)；差壓變送器實(shí)際測(cè)量的介質(zhì)必須要與變送器接觸材質(zhì)兼容。以免損壞或腐蝕變送器元器件。 </p> <p> 第四步：差壓變送器的防爆性；防爆參數(shù)是差壓變送器的一個(gè)重要技術(shù)參數(shù)，現(xiàn)場(chǎng)有防爆要求的必須采用防爆型差壓變送器。防爆的類(lèi)型也有所不同，有本安防爆、隔離防爆、粉塵防爆等不同要求。 </p> <p> 第五步：差壓變送器的顯示功能：因具體使用需求的差別，需不需要差壓變送器的顯示功能，也是要進(jìn)行選擇的。帶顯示差壓變送器能實(shí)時(shí)監(jiān)測(cè)差壓的測(cè)量值，當(dāng)然，帶顯示的價(jià)格會(huì)比不帶顯示的高一些。 </p> <p> <br /> LED顯示壓力變送器分類(lèi)</p><p
