320px;" alt="樂山氧化鋯分析儀推薦,氧化鋯分析儀" src="http://tyunfile.71360.com/UploadFile/cdwckj/637110730022753906/9182129.jpg"></div><p> 氧化鋯分析儀的氧化鋯頭金屬化工藝及儀表信號轉(zhuǎn)換器實(shí)現(xiàn)智能化等方面較大改進(jìn)，具體內(nèi)容如下： </p> <p> （1）多孔性鉑電極的化學(xué)配方及制作工藝可保證氧量檢測器氧化鋯探頭在鍋爐煙氣氛中有足夠的使用壽命。 </p> <p> （2）儀表具有多種線性量程選擇。 </p> <p> （3）儀表溫度控制系統(tǒng)所給出的升溫曲線能滿足氧化鋯材料對升溫速度的要求。 </p> <p> （4）儀表信號具有必要的自診斷功能。 </p> <p> 1、工作原理 </p> <p> 本儀器依據(jù)濃差電池原理構(gòu)成，和其他電池一樣，它具有兩個半電池，而在兩電極之間，用固體電介質(zhì)氧化鋯聯(lián)結(jié)。 </p> <p> 在高溫下，當(dāng)氧化鋯兩側(cè)有氧濃差時，就形成了氧濃差電池，電池電動勢的大小可依據(jù)Nernst公式計(jì)算 </p><p> 氧化鋯氧量分析儀的構(gòu)成是由氧傳感器（又稱氧探頭、氧檢測器）、氧分析儀（又稱變送器、變送單元、轉(zhuǎn)換器、分析儀）以及它們之間的連接電纜等組成。 </p> <p> 傳感器裝置由不銹鋼外殼、測量電池、加熱器、熱電偶、過濾元件以及電纜接線端子等組成。測量電池本體分為3層：鉑（電極）─氧化鋯（電解質(zhì)）─鉑（電極）。鉑電極是多孔性的。煙道氣體通過過濾器或校驗(yàn)氣體通過傳導(dǎo)管進(jìn)入測量電池被測氣體一側(cè)，而另一側(cè)為參比空氣（含氧20.60％）。 </p> <p> 兩種含氧濃度不同的氣體作用在測量電池，便產(chǎn)生一個以對數(shù)為規(guī)律的電勢（兩側(cè)的氧濃度差愈大，電勢信號愈大）。毫伏信號經(jīng)氧分析儀轉(zhuǎn)換成4－20mA標(biāo)準(zhǔn)電流。此電流由氧分析儀接線端子輸出。 </p><p> 變送器把所測量出的數(shù)據(jù)，經(jīng)單片機(jī)計(jì)算轉(zhuǎn)換，將氧含量在數(shù)碼管上顯示出來，同時轉(zhuǎn)換成電流信號供計(jì)算機(jī)或計(jì)錄儀使用。 </p> <p> 700℃和750℃時氧濃度與氧濃差電勢關(guān)系見附表． </p> <p> 三、氧化鋯氧量分析儀（氧探頭）技術(shù)指標(biāo) </p> <p> 量程： 0.01～25.0%O2(量程從5.00％－25.00％內(nèi)自由設(shè)置） </p> <p> 輸出信號： 4 ～20mA 負(fù)載電阻≤500Ω 隔離 </p> <p> 重復(fù)性：滿量程的±0.5% </p> <p> 基本誤差： ≤±2%（滿量程） </p> <p> 穩(wěn)定性： ≤±1%（儀器連續(xù)檢定4h） </p> <p>
