style="text-indent:25px">化工、石油、煤炭等行業(yè)工作環(huán)境中有危險性氣體或者粉塵的存在，因此安裝防爆攝像頭是非常必要的，保障工業(yè)生產(chǎn)安全環(huán)境，是防爆監(jiān)控攝像機存在的主要意義。現(xiàn)在工廠對生產(chǎn)安全的重視程度越來越高，而且對于工作效率的要求也是越來越高，工廠要提高生產(chǎn)安全，提高生產(chǎn)效率，合理利用人力資源，防爆攝像頭起到了很大的作用，現(xiàn)在簡單為大家介紹一下防爆監(jiān)控設(shè)備的相關(guān)知識。防爆監(jiān)控鏡頭如何選擇：防爆攝像頭選鏡頭的原理如同普通攝像機，有4-25MM鏡頭可選。主要根據(jù)現(xiàn)場要監(jiān)控的距離和范圍來選定合適的鏡頭。例如被監(jiān)控物體離安裝點大約30米距離，那么應(yīng)該選12MM或者16MM鏡頭。想看得清楚些，棗莊市內(nèi)防爆攝像頭廠家，那就選16MM鏡頭，模糊一些，選12MM鏡頭。實際上鏡頭有個長度理論值，鏡頭毫米數(shù)乘以2，等于被測物體的距離。鏡頭的缺陷是看寬不看遠，看遠不看寬。鏡頭毫米數(shù)越小，棗莊市內(nèi)防爆攝像頭廠家，那么范圍越大，反之距離越短，棗莊市內(nèi)防爆攝像頭廠家。防止對地絕緣的焊件，焊機的空載電壓或工作電壓延伸。棗莊市內(nèi)防爆攝像頭廠家</p><div

style="text-indent:25px">如何選擇防爆攝像頭：早期的防爆攝像頭以本質(zhì)安全型和正壓型為主。本質(zhì)安全型防爆攝像頭的特點在于對攝像機的電路進行本質(zhì)安全處理，電氣線路輸出或輸入均被設(shè)計控制在不足以產(chǎn)生使氫氣發(fā)生引火的能量以下，使其在正常工作中不會產(chǎn)生電火花、電弧及高溫，從而避免易爆物質(zhì)。這種類型的防爆監(jiān)控機結(jié)構(gòu)單位成本過高是較大缺點，此外也不利于日后的升級。正壓型是早期美系防爆攝像頭產(chǎn)品的常用結(jié)構(gòu)，使用中維護相當(dāng)不便，如不精心維護，危險性相當(dāng)大。此結(jié)構(gòu)目前除極少數(shù)地區(qū)廠商仍在制造外，基本已被較全淘汰。防爆攝像頭是防爆工業(yè)電視系統(tǒng)的中心設(shè)備，但由于市場上的產(chǎn)品良莠不齊，加之信息不對稱，某些無認證、無生產(chǎn)、無售后的“三無”廠家，以假亂真，隨意更改國家標(biāo)準(zhǔn)，降低品質(zhì)要求，以次充好。這種魚龍混雜的局面使設(shè)備選型形同霧里看花，難以抉擇。雖然完全了解一家企業(yè)的質(zhì)量管理體系并非易事，卻可以讓產(chǎn)品告訴我們許多秘密，正所謂窺一斑而知全豹。棗莊市內(nèi)防爆攝像頭廠家</p></p><br
