氯(lv)化(hua)氫氣(qi)體是一(yi)種有危害性的氣(qi)體，所(suo)以在要在儲存的地點安裝檢(jian)測儀器(qi)。那下(xia)面小編就為您介紹一(yi)下(xia)有關氯(lv)化(hua)氫檢(jian)測儀的知(zhi)識(shi)，這有利(li)于您對檢(jian)測儀原理的認識(shi)。

    氯(lv)化(hua)氫(qing)檢(jian)測(ce)(ce)儀采用(yong)(yong)進(jin)(jin)口原裝安培型電(dian)(dian)(dian)(dian)(dian)化(hua)學傳(chuan)感器，通常由(you)浸(jin)沒在電(dian)(dian)(dian)(dian)(dian)解液(ye)中(zhong)的(de)(de)(de)(de)(de)三個(ge)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)構成(cheng)。工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)是用(yong)(yong)具有催化(hua)活性的(de)(de)(de)(de)(de)金屬(shu)，將其(qi)(qi)涂(tu)覆(fu)在透氣但憎水的(de)(de)(de)(de)(de)膜上(shang)(shang)做成(cheng)。被測(ce)(ce)量(liang)氣體經擴(kuo)散透過多孔(kong)的(de)(de)(de)(de)(de)膜，在其(qi)(qi)上(shang)(shang)進(jin)(jin)行電(dian)(dian)(dian)(dian)(dian)化(hua)學氧(yang)化(hua)或(huo)還原反(fan)應，其(qi)(qi)反(fan)應的(de)(de)(de)(de)(de)性質(zhi)(zhi)依(yi)工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)熱力學電(dian)(dian)(dian)(dian)(dian)位(wei)(wei)和分析氣體的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)化(hua)學性質(zhi)(zhi)而定。氯(lv)化(hua)氫(qing)檢(jian)測(ce)(ce)儀電(dian)(dian)(dian)(dian)(dian)化(hua)學反(fan)應中(zhong)參加反(fan)應的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子(zi)流(liu)(liu)入或(huo)流(liu)(liu)出(chu)工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)。氯(lv)化(hua)氫(qing)檢(jian)測(ce)(ce)儀工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)工(gong)(gong)作(zuo)信號(hao)經運放U2放大(da)成(cheng)為儀器的(de)(de)(de)(de)(de)輸出(chu)信號(hao)。電(dian)(dian)(dian)(dian)(dian)路(lu)同(tong)時保(bao)持(chi)工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓使之處于其(qi)(qi)偏(pian)壓VBIAS之值。基準電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)則為電(dian)(dian)(dian)(dian)(dian)解液(ye)中(zhong)的(de)(de)(de)(de)(de)工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)提供(gong)一(yi)個(ge)穩定的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)位(wei)(wei)。基準電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)電(dian)(dian)(dian)(dian)(dian)位(wei)(wei)與VBIAS比(bi)較后，在運放U1輸出(chu)電(dian)(dian)(dian)(dian)(dian)壓信號(hao)，其(qi)(qi)大(da)小正好是產生一(yi)個(ge)與工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)相等(deng)相反(fan)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)信號(hao)。同(tong)時電(dian)(dian)(dian)(dian)(dian)路(lu)使工(gong)(gong)作(zuo)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)與參比(bi)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)間保(bao)持(chi)恒定的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)位(wei)(wei)差。測(ce)(ce)量(liang)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)只是一(yi)個(ge)完整的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)化(hua)學傳(chuan)感器所需(xu)要(yao)的(de)(de)(de)(de)(de)第二電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)，其(qi)(qi)主要(yao)作(zuo)用(yong)(yong)是允許(xu)電(dian)(dian)(dian)(dian)(dian)子(zi)進(jin)(jin)入或(huo)流(liu)(liu)出(chu)電(dian)(dian)(dian)(dian)(dian)解液(ye)。

    氯化(hua)氫檢(jian)測(ce)儀主要用于煤(mei)礦、冶金、化(hua)工、液化(hua)氣(qi)(qi)站等行業檢(jian)測(ce)有(you)害氣(qi)(qi)體濃度及其他工作環(huan)境中的(de)(de)有(you)害氣(qi)(qi)體，對(dui)于危險氣(qi)(qi)體的(de)(de)檢(jian)測(ce)很(hen)是(shi)重(zhong)要。
