NDIR系統(tǒng)存在的一個(gè)主要問題是隨著時(shí)間的推移，如何準(zhǔn)確地知道發(fā)送給檢測(cè)器的光線變化是否真的因氣體吸收所引起，而不是光源變化或者艙室污染所引起。盡管在NDIR系統(tǒng)工作之初進(jìn)行校正是可能的，但是為了應(yīng)對(duì)隨著時(shí)間推移而出現(xiàn)的光源變化和艙室污染問題，要求不斷進(jìn)行校準(zhǔn)。這樣做成本很高昂、耗費(fèi)時(shí)間，并且在長(zhǎng)期現(xiàn)場(chǎng)運(yùn)行過程中也不可行。解決這個(gè)問題的一個(gè)方法是，在你的系統(tǒng)中使用一條基準(zhǔn)通道。該基準(zhǔn)通道包含一個(gè)檢測(cè)器，在沒有光線吸收的范圍內(nèi)測(cè)量光源。現(xiàn)在，氣體濃度由兩個(gè)發(fā)送光量之比來決定。光源偏差引起的任何誤差現(xiàn)在都被抵消。這種偏差導(dǎo)致長(zhǎng)期漂移，其出現(xiàn)在較大的時(shí)間段內(nèi)。因此，無需同時(shí)對(duì)基準(zhǔn)和有源通道進(jìn)行采樣。你可以使用一個(gè)輸入多路復(fù)用器(MUX)來在兩條通道之間切換，從而降低系統(tǒng)成本和復(fù)雜程度，并同時(shí)維持度

在NDIR系統(tǒng)中用作紅外檢測(cè)器的熱電堆根據(jù)其接收的入射光多少(單位為瓦特)來產(chǎn)生電壓。被測(cè)氣體類型、其吸光系數(shù)和氣體濃度范圍都影響熱電堆檢測(cè)器的入射光線量。它產(chǎn)生熱電堆輸出電壓(范圍通常為數(shù)十μV)。因此，你需要設(shè)計(jì)出具有使用不同增益放大熱電堆輸出電壓功能的電子支持組件?？梢酝ㄟ^一個(gè)含內(nèi)置PGA的模擬前端(AFE)來處理這種情況。要求使用數(shù)百到數(shù)千V/V范圍的增益設(shè)置，來把小熱電堆信號(hào)放大到系統(tǒng)全刻度模數(shù)轉(zhuǎn)換器(ADC)，從而實(shí)現(xiàn)大系統(tǒng)度。
