一、工作原理(li)

電化學(xue)法：水(shui)中(zhong)溶氧(yang)量(liang)(liang)一(yi)般(ban)采用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)化(hua)學法測(ce)(ce)(ce)量(liang)(liang)，以 COS4 氧(yang)量(liang)(liang)測(ce)(ce)(ce)量(liang)(liang)傳(chuan)感器(qi)(qi)為例，其電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極由陰(yin)極（常用(yong)金(jin)和鉑制(zhi)成）、帶電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)反(fan)(fan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極（銀）和無電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流的(de)(de)參(can)比(bi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極（銀）組(zu)成，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極浸(jin)沒在電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)質如 KCl、KOH 中(zhong)，傳(chuan)感器(qi)(qi)有隔膜(mo)覆(fu)蓋，隔膜(mo)將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解(jie)質與被(bei)測(ce)(ce)(ce)量(liang)(liang)的(de)(de)液體分開。當測(ce)(ce)(ce)量(liang)(liang)元件浸(jin)入有溶解(jie)氧(yang)的(de)(de)水(shui)中(zhong)，氧(yang)會通過隔膜(mo)擴(kuo)散，在陰(yin)極上(shang)(shang)被(bei)還(huan)原成氫氧(yang)根(gen)離子，同時氯化(hua)銀沉淀在反(fan)(fan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)極上(shang)(shang)，形成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流大小與被(bei)測(ce)(ce)(ce)污(wu)水(shui)的(de)(de)氧(yang)分壓成正比(bi)，該信(xin)號連(lian)同傳(chuan)感器(qi)(qi)上(shang)(shang)熱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻測(ce)(ce)(ce)出(chu)(chu)的(de)(de)溫度信(xin)號被(bei)送(song)入變送(song)器(qi)(qi)，利用(yong)傳(chuan)感器(qi)(qi)中(zhong)存儲的(de)(de)含氧(yang)量(liang)(liang)和氧(yang)分壓、溫度之間的(de)(de)關(guan)系曲線計算(suan)出(chu)(chu)水(shui)中(zhong)的(de)(de)含氧(yang)量(liang)(liang)，然后轉(zhuan)化(hua)成標準信(xin)號輸出(chu)(chu)。
