style="text-indent:25px">不銹鋼防爆攝像機護(hù)罩的耐腐性比碳鋼好。不銹鋼按組織狀態(tài)分為：馬氏體鋼、鐵素體鋼、奧氏體鋼、奧氏體-鐵素體（雙相）不銹鋼及沉淀硬化不銹鋼等。其中沉淀硬化型不銹鋼是通過熱處理手段使鋼中碳化物沉淀析出，從而提高的鋼強度，具有很好的成形性能和良好的焊接性，可作為超大強度的材料在核工業(yè)、航空和航天工業(yè)中應(yīng)用。不銹鋼防爆攝像機護(hù)罩主要采用304不銹鋼材質(zhì)，產(chǎn)品表面可應(yīng)客戶需求選擇原面加工（不銹鋼原色）或高溫噴涂氟碳烤漆的防銹處理。由于不銹鋼防爆攝像機護(hù)罩對碳含量的要求高于碳鋼，因而工藝更為復(fù)雜，以及它們所含其他成分的差異，成本上碳鋼防爆攝像機護(hù)罩優(yōu)于不銹鋼；從不銹鋼和碳鋼的防腐蝕性來說，不銹鋼防爆攝像機護(hù)罩更勝一籌，并且同種產(chǎn)品，不銹鋼產(chǎn)品更輕。因此，在相對優(yōu)勢和劣勢并存的情況下，企業(yè)應(yīng)該根據(jù)自身的需求來選擇合適材質(zhì)的產(chǎn)品。延安無線防爆攝像頭廠家推薦防爆監(jiān)控攝像機使用：危險下限＞10%的可燃?xì)怏w。</p><div

style="text-indent:25px">防爆攝像機解析度技術(shù)分析：垂直清晰度完全由信號格式?jīng)Q定，這非常易懂。而水平清晰度卻是較容易令人混淆的概念，其中較大的問題就是因為水平清晰度有多種表達(dá)方式。在防爆攝像機這樣的視頻監(jiān)控領(lǐng)域，我們更習(xí)慣使用“每圖像高度”的像素多少來表示水平清晰度，或者稱之為“電視線”。這種習(xí)慣的由來要追溯到電視機誕生的60年前。當(dāng)時，由于信號的格式已經(jīng)決定了圖像的垂直清晰度，因此**們的想法是用和垂直清晰相關(guān)的方式來表示水平清晰度。也就是說，到底是水平方向更清晰還是垂直方向更清晰，通過這個相對的清晰度表示就可以一目了然。由于這個原因，水平清晰度被定義為：在和屏幕高度相等的水平方向上可以顯示的像素數(shù)。在這種定義下得到的清晰度就叫做“電視線”，也就是所謂的線數(shù)。所以，當(dāng)仍然聽到別人講視頻信號有多少清晰度的時候，它并不是指從圖像較左邊到較右邊有多少像素組成，而是指在和圖像高度相同的水平寬度上有多少像素。</p><p style="text-indent:25px">防爆攝像機如何防水防霧：攝像機防護(hù)罩會出現(xiàn)水霧等現(xiàn)象的另一原因還在于設(shè)備密封性不佳，比如攝像機接縫、螺絲口等地方都會出現(xiàn)漏水的現(xiàn)象。如果要解決這一問題，廠商必須要下足功夫，考慮是否采用凹底槽設(shè)計，或在螺絲接口墊橡膠墊等。其實，不要小看監(jiān)控攝像機上的任何一個小部件，因為有了它才能夠讓監(jiān)視過程更完美。如果你不想給你的球機留遺憾，是否想過在極端天氣下更換隱形雨刷玻璃罩呢？機器內(nèi)部出現(xiàn)霧氣：霧、霜的形成是由于空氣中的飽和水蒸氣遇冷凝結(jié)而成，因冷環(huán)境的強、弱分別凝結(jié)成霜和霧。紅外攝像機在工作過程中，尤其是在室內(nèi)的攝像機常常會因場館內(nèi)的霧氣或者水汽等原因在防護(hù)罩視窗玻璃上形成霧或霜，導(dǎo)致攝像機無法看清物體，直接影響監(jiān)控效果。防爆攝像機維護(hù)：合理安排監(jiān)控中心的監(jiān)控網(wǎng)絡(luò)需求，如帶寬、IP地址等限制。</p><div

style="text-indent:25px">防爆攝像頭的發(fā)展與類型：為了實現(xiàn)在易燃易爆的現(xiàn)場環(huán)境中應(yīng)用工業(yè)電視監(jiān)控，防爆攝像頭便應(yīng)運而生了。較初的需求是來自于煤礦井下。尤其是近十年，隨著國家工業(yè)化進(jìn)程，防爆要求的需求擴(kuò)大至各個領(lǐng)域石油、化工、航海、航天、冶金、科研和**工業(yè)等需求更甚，要求各異，針對性更強，特別是我國石化工業(yè)的迅猛發(fā)展，加速了防爆工業(yè)監(jiān)控、防爆工業(yè)擴(kuò)音對講產(chǎn)品的發(fā)展。防爆攝像頭也隨之開始在各個領(lǐng)域普遍使用。值得注意的是，與電子工業(yè)的普遍情況不同，中國的防爆攝像頭的發(fā)展就時間而言在國際同行業(yè)中是相當(dāng)早的，就技術(shù)水平而言，也是始終不亞于國外同類產(chǎn)品的。防爆紅外攝像機不清晰解決：采用雙濾光片或者雙玻璃結(jié)構(gòu)，提高晚上紅外燈的攝入程度和避免水霧影響鏡頭。延安無線防爆攝像頭廠家推薦</p><p

style="text-indent:25px">由于防爆攝像機身處十分危險的環(huán)境中工作，對煤礦、開井作業(yè)提供安全保障，對人身安全起到了至關(guān)重要的作用。防爆攝像機能夠有效壓制可能發(fā)生危險的情況，可以檢測到易燃易爆物體的濃度等，甚至可以探測到有威脅的熱量。考慮到應(yīng)用環(huán)境的特殊性，防爆攝像機也由原來的視頻線+電源電纜升級到網(wǎng)絡(luò)監(jiān)控模式。圖像畫質(zhì)質(zhì)量有明顯提升，在傳輸介質(zhì)上也避開了電源，采用網(wǎng)線或光纖供電及傳輸數(shù)據(jù)。以及逐漸開發(fā)和應(yīng)用的智能化，網(wǎng)絡(luò)化，IP化等方向發(fā)展。青島防爆攝像頭</p></p><br
