防爆型,本安型熱電偶

概述     工業(yè)用隔爆熱電偶是一種溫度傳感器，在化學(xué)工業(yè)自控系統(tǒng)中應(yīng)用極廣，通過溫度傳感器， 可將控制對象的溫度參數(shù)變成電信號，傳遞給顯示、記錄和調(diào)節(jié)儀，對系統(tǒng)施行檢測、 調(diào)節(jié)和 控制。     在化工廠，生產(chǎn)現(xiàn)場常伴有各種易燃、易爆等　化學(xué)氣體、蒸汽，如果使用普通的熱電偶非 常不安全，極易引起環(huán)境氣體爆炸。因此，在這些場合必須使用隔爆熱電偶作溫度傳感器，本公 司生產(chǎn)的隔爆型熱電偶產(chǎn)品,適用于　dⅡCT6溫度組別區(qū)間內(nèi)的具有爆炸性氣體危險的場所內(nèi)。   工作原理:     如果由兩種不同成份的均質(zhì)導(dǎo)體（熱電極）組成閉合回路,當(dāng)兩端存在溫度梯度時,回路中就有電流通過,那么兩端之間就存在熱電勢（ 如下圖所示）   防爆原理:     利用間隙隔爆原理，設(shè)計具有足夠強度的接線盒等部件，將所有會產(chǎn)生火花、電弧和危險溫度的零部 件都密封在接線盒內(nèi)，當(dāng)腔內(nèi)發(fā)生爆炸時，能通過接合面間隙熄 火和冷卻，使爆炸后的火焰和溫度不傳到腔外   特 點 : 按符合IEC標(biāo)準(zhǔn)的防爆規(guī)程GB3836設(shè)計; 采用兩腔式隔爆結(jié)構(gòu),更換測溫元件簡便,使用安全可靠 防爆標(biāo)志dⅡCT6,適用于ⅡC級以下,引燃溫度T6以上,含爆炸性氣體場合的溫度測量。
