class="title">詳細說明</p><div id="8qnzwd7" class="box"><p><p> 氧化鋯氧量分析儀的構成是由氧傳感器（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，瀘州氧化鋯分析儀批發(fā)、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）─鉑（電極）。鉑電極是多孔性的。煙道氣體通過過濾器或校驗氣體通過傳導管進入測量電池被測氣體一側，而另一側為參比空氣（含氧20.60％）。 </p> <p> 兩種含氧濃度不同的氣體作用在測量電池，便產生一個以對數(shù)為規(guī)律的電勢（兩側的氧濃度差愈大，瀘州氧化鋯分析儀批發(fā)，瀘州氧化鋯分析儀批發(fā)，電勢信號愈大）。毫伏信號經氧分析儀轉換成4－20mA標準電流。此電流由氧分析儀接線端子輸出。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="瀘州氧化鋯分析儀批發(fā)" src="http://tyunfile.71360.com/UploadFile/cdwckj/637110730026513672/568819.jpg"></div><p> 氧化鋯氧量分析儀（氧探頭） </p> <p> 氧化鋯是一種高溫電解質濃差電池，在數(shù)度的高溫環(huán)境下，具有能產生氧離子遷移的導電性能，由于被測氣體（煙氣或其它氣體）與參比氣體（空氣或其它氣體）在氧化鋯兩側鉑電極的氧分壓不同，在兩極間有一定數(shù)量的氧離子遷移而產生了氧濃差電勢，其電勢值與氧濃度的關系，可以用能斯特（Nernst）公式來表示： </p> <p> E=RT/4F×LnP1/P2 </p> <p> 公式中：E—氧濃差電勢（V） </p> <p> R—理想氣體常數(shù)（8.314J/moLK） </p> <p> T—溫度值（K） </p> <p> F—法拉第常數(shù)（96500c/moL） </p> <p> P1—參比氣體分壓（空氣） </p> <p> P2—被測氣體分壓 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="瀘州氧化鋯分析儀批發(fā)" 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換器實現(xiàn)智能化等方面較大改進，具體內容如下： </p> <p> （1）多孔性鉑電極的化學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> 本儀器依據濃差電池原理構成，和其他電池一樣，它具有兩個半電池，而在兩電極之間，用固體電介質氧化鋯聯(lián)結。 </p> <p> 在高溫下，當氧化鋯兩側有氧濃差時，就形成了氧濃差電池，電池電動勢的大小可依據Nernst公式計算 </p></p><br /><p>文章來源地址:
