防爆型壓力變送器是通過(guò)被測(cè)的氣體或者液體的施壓，使得防爆壓力變送器的電阻值發(fā)生變化（電阻效應(yīng)），將測(cè)量的相對(duì)應(yīng)的信號(hào)轉(zhuǎn)化成相對(duì)應(yīng)的4~20mA輸出信號(hào)或者帶HART協(xié)議的數(shù)字信號(hào)以進(jìn)行通訊。防爆型壓力變送器安全防爆，可廣泛應(yīng)用于石化、電力、冶金、制藥、食品加工等行業(yè)。 </p> <p> 防爆型壓力變送器應(yīng)用的性危險(xiǎn)場(chǎng)所可分為0區(qū)、1區(qū)和2區(qū)。所謂0區(qū)是指在正常情況下，性氣體混合物連續(xù)的或長(zhǎng)時(shí)間地存在的場(chǎng)所；1區(qū)是指在正常情況下，性氣體混合物有可能出現(xiàn)的場(chǎng)所，2區(qū)指的是在正常情況下，性氣體不可能出現(xiàn)或即使出現(xiàn)也只是短暫時(shí)間存在的場(chǎng)所。對(duì)于防爆型壓力變送器來(lái)說(shuō)，對(duì)0區(qū)的防爆要求是為嚴(yán)格的。壓力變送器可以是本安型、隔爆型，需要注意的是，不管什么形式的防爆型壓力變送器，均需要有國(guó)家防爆檢測(cè)部門的核實(shí)、取得相關(guān)防爆證書方可使用。 </p> <p> 防爆型壓力變送器中本安型需要配合安全柵才能在有性混合物的危險(xiǎn)場(chǎng)所使用。安全柵是靠控制能量來(lái)達(dá)到防爆規(guī)定的。本質(zhì)安全型防爆壓力變送器為了安全起見，應(yīng)區(qū)別本質(zhì)安全回路及非本質(zhì)安全回路，把本質(zhì)安全回路的接線與其它的電氣回路的接線分開走線。煙塵治理壓力變送器性能壓力變送器的殼體、過(guò)程連接與膜片采用的都是不銹鋼材質(zhì)，測(cè)量介質(zhì)要與304、316不銹鋼兼容。</p><div

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(guò)**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(guò)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(guò)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)。 </p><p> 溫度變從兩方面影響著壓力變送器的輸出，一是零點(diǎn)漂移，二是影響滿量程輸出。如：滿量程的+/-X%℃，讀數(shù)的+/-X%℃，在超出溫度范圍時(shí)滿量程的+/-X%，在溫度補(bǔ)償范圍內(nèi)時(shí)讀數(shù)的+/-X%，如果沒有這些參數(shù)，會(huì)導(dǎo)至在使用中的不確定性。壓力變送器輸出的變化到底是由壓力變化引起的，還是由溫度變化引起的。溫度因素是了解如何使用變送器時(shí)復(fù)雜的一部分。壓力變送器的各項(xiàng)基本參數(shù)是我們考量壓力變送器優(yōu)劣的重要綜合指標(biāo)。在實(shí)際應(yīng)用過(guò)程中，也需要對(duì)各項(xiàng)參數(shù)進(jìn)行嚴(yán)格把控。使得我們的工況安全有效的持續(xù)運(yùn)行。

壓力變送器常用選用方法壓力變送器的輸出信號(hào)與壓力變量之間有一給定的連續(xù)函數(shù)關(guān)系（通常為線性函數(shù)）。為了保證您挑選的變送器符合現(xiàn)場(chǎng)的使用要求，選型時(shí)有幾點(diǎn)需要注意的地方： </p> <p> 1、測(cè)量壓力的類型:壓力類型首要有表壓、絕壓、差壓等；表壓是指以大氣壓力為基準(zhǔn)，小于或大于大氣壓力的壓力；絕壓是指以肯定壓力零位為基準(zhǔn)，高于肯定壓力零位的壓力；差壓是指兩個(gè)壓力之間的差值。 </p> <p> 2、準(zhǔn)確度等級(jí):變送器的測(cè)量誤差錯(cuò)按精度等級(jí)來(lái)劃分，實(shí)際使用過(guò)程中，依據(jù)測(cè)量誤差的需求并本著適用經(jīng)濟(jì)的原則進(jìn)行挑選。 </p> <p> 3、體系的比較大過(guò)載:體系的比較大過(guò)載應(yīng)小于變送器的過(guò)載維護(hù)極限，否則會(huì)影響商品的運(yùn)用壽命乃至損壞商品。2倍丈量規(guī)模的過(guò)載維護(hù)是我公司商品的規(guī)范裝備（也可依據(jù)客戶請(qǐng)求進(jìn)行定制）。 </p> <p> 4、測(cè)量范圍:一般按實(shí)際測(cè)量壓力為測(cè)量范圍的80%挑選。 </p> <p> <br /> 河北經(jīng)濟(jì)型壓力變送器哪個(gè)好</p><p
