輻射溫度計(jì)是怎么校準(zhǔn)黑體輻射源的？輻射溫度計(jì)的光路一般有兩種形式，即變焦距和定焦距。輻射溫度計(jì)的靶標(biāo)為測(cè)溫儀光路是變焦距，并聚焦到黑體腔底。從光路圖可看出，通過(guò)黑體腔口的面積比到腔底的大，對(duì)于等溫黑體，只要腔口充滿視場(chǎng)，測(cè)量的溫度就準(zhǔn)確。沒(méi)有必要將鏡頭聚焦到腔底。如果鏡頭聚焦到黑體腔底，當(dāng)黑體腔和黑體的前沿段都較長(zhǎng)時(shí)，為了滿足測(cè)溫的要求，這勢(shì)必要增加管式黑體的內(nèi)徑和腔口直徑，否則，腔口的尺寸就不能充滿測(cè)溫儀的視場(chǎng)，測(cè)溫就不準(zhǔn)確。

黑體輻射源主要用于校準(zhǔn)輻射溫度計(jì)、紅外溫度計(jì)等非接觸式輻射測(cè)溫儀器。黑體源的主要技術(shù)指標(biāo)為黑體腔口發(fā)射率和輻射溫度準(zhǔn)確性。除黑體腔的特殊設(shè)計(jì)外，腔體內(nèi)壁面溫度均勻性，是黑體技術(shù)的關(guān)鍵之一。上海蕓尖智能公司目前擁有國(guó)內(nèi)先進(jìn)的黑體研究和制造技術(shù)，產(chǎn)品種類全、溫度范圍寬的黑體系列產(chǎn)品。球形腔黑體系列的工作溫度為 -50～1700℃ </p><p> 等溫黑體的探討：現(xiàn)假定有一不等溫黑體腔，將其溫度不均勻近似劃為3個(gè)區(qū)域，為了簡(jiǎn)化計(jì)算并將各面看作相等，光譜發(fā)射率均看作1（只考慮溫度差異的影響，而不考慮發(fā)射率的影響），每個(gè)區(qū)域只看作一個(gè)溫度（即等價(jià)溫度），后面用算術(shù)平均值作為黑體腔的溫度。計(jì)算結(jié)果得出，對(duì)于不等溫黑體，光譜能量迭加后當(dāng)量溫度，不等于不同面積上的溫度算術(shù)加權(quán)平均值。波長(zhǎng)越短，當(dāng)量溫度越高，如果算術(shù)平均值為298.33℃（溫度差異性為±35℃），在0.665μm波長(zhǎng)處，當(dāng)量溫度為318.62℃；而在5μm當(dāng)量溫度為300.86℃；隨著波長(zhǎng)的增加，當(dāng)量溫度值趨向算術(shù)加權(quán)平均值，接近300℃。在平均溫度1098.33℃時(shí)（溫度差異性±35℃），0.665μm的當(dāng)量溫度為1102.94℃，與平均溫度差4.6℃；?5μm處當(dāng)量溫度為1098.57℃，與平均溫度基本接近。那么溫度究竟以哪個(gè)為準(zhǔn)？很難有個(gè)確定的標(biāo)準(zhǔn)。不等溫黑體內(nèi)表面的溫度差異性越大，當(dāng)量溫度和算術(shù)加權(quán)平均溫度之差也越大。在相同的溫度差異性上，隨著黑體自身溫度的升高，當(dāng)量溫度與平均溫度差值下降。

黑體使用過(guò)程中的使用日常維護(hù)及注意事項(xiàng)： </p> <p> 注意事項(xiàng)一：黑體爐的溫度上限值不可長(zhǎng)時(shí)間使用，否則會(huì)造成爐膛被燒壞！應(yīng)該保留10%～15%的余量。 </p> <p> 注意事項(xiàng)二：高溫黑體爐升溫后，需要散熱降溫。使用完畢后，不可盲目切斷黑體爐的供電。否則會(huì)造成散熱受阻，儀器被燒壞！應(yīng)該先關(guān)閉黑體爐本機(jī)電源或者把黑體爐溫度設(shè)置為0（但是風(fēng)扇仍然在運(yùn)轉(zhuǎn)）一段時(shí)間后，黑體爐顯示溫度為200℃以下時(shí)，確認(rèn)風(fēng)扇停止運(yùn)轉(zhuǎn)后，再關(guān)閉總電源！（低溫及常溫黑體爐風(fēng)扇可能不會(huì)啟動(dòng)!） </p> <p> 注意事項(xiàng)三：黑體腔輻射表面涂有昂貴的黑體漆，請(qǐng)不要用手指等試圖直接擦拭，否則會(huì)造成黑體腔輻射表面受污染，輻射率下降。 </p> <p> 注意事項(xiàng)四：在黑體爐工作的時(shí)候一定不要去觸碰其表面的紅外目標(biāo)源。紅外目標(biāo)源上表面的溫度都會(huì)在顯示器上顯示出來(lái)，它實(shí)際的溫度和顯示溫度是一樣的，假如，黑體爐設(shè)置的溫度為200℃，那么黑體靶心的位置的溫度就是200℃，而在其周圍區(qū)域的溫度也非常高，如果觸碰其表面，就會(huì)很容易使自己燒傷; </p> <p> 注意事項(xiàng)五如果在沒(méi)有正確的連接黑體爐電源線的時(shí)候，請(qǐng)不要立即開(kāi)啟或者操作黑體爐，請(qǐng)讓專業(yè)人員檢查后方可繼續(xù)使用。 </p> <p> <br /> 上海熱像儀黑體爐</p></p><br /><p>文章來(lái)源地址:
