</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，河北防腐壓力變送器價(jià)格查詢、組合使用。習(xí)慣上24V

工作原理相同：壓力變送器與差壓變送器都是通過(guò)壓阻效應(yīng)產(chǎn)生的電壓信號(hào)，經(jīng)過(guò)放大、零點(diǎn)和靈敏度溫度補(bǔ)償來(lái)實(shí)現(xiàn)其終的測(cè)量。 </p> <p> 輸出信號(hào)相同：不管是壓力變送器還是差壓變送器，都能進(jìn)行4～20 mA 的電流輸出、RS485 數(shù)字信號(hào)輸出和0～10 VDC、0～5 VDC等電壓信號(hào)輸出。 </p> <p> 壓力變送器與差壓變送器的不同點(diǎn)： </p> <p> 壓力端的不同：壓力變送器只能測(cè)量一個(gè)壓力端的壓力，而差壓變送器可以測(cè)量?jī)蓚€(gè)壓力點(diǎn)的壓力，兩者壓力相減，正壓端壓力減負(fù)壓端壓力得出壓力差值。 </p> <p> 連接方式的不同：壓力變送器一般采用的都是螺紋連接，差壓變送器除了可采用螺紋連接，更多的則選用寶塔嘴和快接口的連接方式，可直接接相應(yīng)直徑的軟管。安裝更加方便。陜西設(shè)備級(jí)壓力變送器哪里買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。</p><div

壓力變送器輸出電流波動(dòng)或不穩(wěn)定故障: </p> <p> 壓力變送器在使用過(guò)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(lái)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(wú)，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(méi)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(wèn)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 /> 靈敏度指相對(duì)于被測(cè)量變化的位移率，靈敏度是衡量物理儀器的標(biāo)志，特別是電學(xué)儀器注重儀器靈敏度的提高。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

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 /> 從精度角度來(lái)分類，因?yàn)槲覈?guó)國(guó)標(biāo)的精度就為0.5%.　所以近年來(lái)又可以分為高精度壓力變送器和一般壓力變送器。陜西設(shè)備級(jí)壓力變送器哪里買</p><p
