熱傳導(dǎo)式氣體分析儀表是根據(jù)不同氣體具有不同熱傳導(dǎo)能力的原理，通過測定混合氣體導(dǎo)熱系數(shù)來推算其中某些組分的含量。這種分析儀表簡單可靠，適用的氣體種類較多，是一種**基本的分析儀表。但是直接測量氣體的導(dǎo)熱系數(shù)比較困難，所以實際上常把氣體導(dǎo)熱系數(shù)的變化轉(zhuǎn)換為電學(xué) 參量的變化來進行測定。熱導(dǎo)式氣體分析儀在氣體檢測領(lǐng)域的應(yīng)用范圍非常***，通常用來檢測氫氣、甲烷、二氧化碳、二氧化硫和低濃度可燃性氣體的含量。半導(dǎo)體式氣體傳感器利用半導(dǎo)體材料表面吸附、脫附氣體分子會引起半導(dǎo)

為參考通道濾光片，透射頻帶中心 4. 0 μm，G1 為氣體測量通道濾光片，透射頻帶中心 4. 64 μm．圖 5 所示為 TPS2534 兩探測窗口濾光片紅外吸收光譜與 CO 吸收光譜的對比圖。可以看出 TPS2534 探測窗口濾光片透射頻帶正好與 CO 吸收峰重合，而參考窗口濾光片透射頻帶遠離 CO 吸收峰，在此頻帶內(nèi)的光強不被其他氣體吸收，可以完整攜帶光源原始光強信息。熱釋電紅外探測器只響應(yīng)變化的光強，因此需要對光源進行一定頻率的調(diào)制。TPS2534 的頻率響應(yīng)曲線。可知 TPS2534 的相對輸出隨著入射紅外光頻率的增加 </p> <p> 而減小，當(dāng)入射紅外光頻率將為 5 Hz 時 TPS2534 的相對輸出降為－ 3
