詳細(xì)介紹




 

一、產(chǎn)品簡(jiǎn)介   Product Brief

       WR系列工業(yè)用隔爆、本安型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(guò)溫度傳感器,可將控制對(duì)象的溫度參數(shù)變成電信號(hào),傳遞給顯示、記錄和調(diào)節(jié)儀表,對(duì)系統(tǒng)實(shí)行檢測(cè)、調(diào)節(jié)和控制。

        WR Series For industrial use Flameproof, Intrinsically safe type thermocouple Is a kind of temperature sensor, In the chemical industry in the automatic control system of wide application, Through the temperature sensor, Can put the control object The temperature parameter to electrical signal, Transferred to display, record and control instrument, On the system The implementation of inspection, regulation and control.

 

       在化工廠,生產(chǎn)現(xiàn)場(chǎng)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(chǎng)合必須使用隔爆或本安型熱電偶作溫度傳感器,本公司生產(chǎn)隔爆或本安型熱電偶產(chǎn)品適用在EX dIICT1~dIICT6溫度組別區(qū)間內(nèi)具有爆炸氣體危險(xiǎn)的場(chǎng)所內(nèi)。

       In the chemical plant, The production site is often accompanied by a variety of flammable, Explosive chemical gas, Steam, If using the ordinary thermocouple very unsafe, Extremely easy to cause environment gas explosion. Therefore, In these situations must use flameproof Or intrinsically safe type thermocouple as temperature sensor, The company production of Flameproof Or intrinsically safe type thermocouple products Applicable in EX dIICT1~dIICT6 Temperature group interval With explosive gases in dangerous places.

 

       本公司生產(chǎn)的隔爆或本安型隔爆熱電偶技術(shù)性能符合ZBN11002-2010工業(yè)熱電偶技術(shù)條件和ZBY300-2010工業(yè)熱電偶分度表及允許誤差,同時(shí)產(chǎn)品均符合爆炸性環(huán)境用防爆電氣設(shè)備通用要求GB3836.1~2010GB3836.2-2010標(biāo)準(zhǔn),由儀器儀表防爆安全監(jiān)督檢驗(yàn)站對(duì)產(chǎn)品的圖樣、技術(shù)文件、樣機(jī)進(jìn)行專(zhuān)門(mén)審定和批準(zhǔn),并以給防爆合格證,隔爆熱電偶合格證號(hào):CNEx14.2076X

       The company production of Flameproof Or intrinsically safe type thermocouple Technical performance in line with ZBN11002-2010 Industrial thermocouple Technology conditions And ZBY300-2010 Industrial thermocouple indexing table And permissible error, At the same time product Accord with the used in explosive environment Explosion proof electrical equipment General requirements GB3836.1~2010GB3836.2-2010 Standard, By the national Explosion-proof instrument of safety supervision and inspection station On the product pattern, Technical documents, Prototype Special Examination and approval, And to give the explosion-proof certificate, Explosion proof thermocouple certificate no.: CNEx14.2076X

 

       本安型隔爆熱電偶必須使用本安補(bǔ)償導(dǎo)線,其分布參數(shù)控制范圍:總電感量≤2mH,電容量≤0.06μ,同時(shí)使用關(guān)聯(lián)設(shè)備安全柵,關(guān)聯(lián)設(shè)備的選用按下原則,熱電偶(必須是絕緣式)配二次儀表時(shí),必須選用FB系列安全柵,安全柵的具體接線見(jiàn)具體產(chǎn)品的說(shuō)明書(shū)。

       Intrinsically safe type thermocouple You must use the intrinsically safe compensation wire, The distributed parameter control range: The total inductance ≤2mHCapacitance≤0.06μAt the same time, the use of Associated equipment safety gate, The device context Selection Press the principle, Thermocouple(must be insulated type) With two instruments, Must be selected FB series of safety barrier, Safety grid Specific wiring See specific product specifications.

 

二、原理結(jié)構(gòu)   The principle structure

       隔爆或本安熱電偶與裝配式熱電偶的結(jié)構(gòu),原理基本相同,所區(qū)別的是,隔爆或本安型產(chǎn)品接線盒(外殼)在設(shè)計(jì)上采用防爆特殊結(jié)構(gòu),接線盒用高強(qiáng)度鋁合金壓鑄而成,并具有足夠的內(nèi)部空間、壁厚和機(jī)械強(qiáng)度,橡膠密封圈的熱穩(wěn)定性均符合防爆標(biāo)準(zhǔn)。所以,當(dāng)接線盒內(nèi)部的爆炸性混合氣體發(fā)生爆炸時(shí),其內(nèi)壓不會(huì)破壞接線盒,而由此產(chǎn)生的熱能不能向外擴(kuò)散傳爆。

       Flameproof Or intrinsically safe thermocouple And the assembly type thermocouple Structure, The same basic principles,The difference is, Flameproof Or intrinsically safe product Junction box (shell) In the design of the Explosion proof special structure, Wiring box for high strength aluminum alloy die-casting and, And has sufficient internal space, Wall thickness and mechanical strength, The rubber sealing ring Thermal stability Are in line with national standards for explosion proof. So, When the wiring inside the box Explosive gas mixture When the explosion, The inner pressure Will not damage the junction box, The resulting Heat energy can not be outward diffusion of detonation.

 

       由于產(chǎn)品采用上述防爆特殊結(jié)構(gòu),使產(chǎn)品*符合使用在dIIBT4dIICT6ibBT4iaIICT6防爆類(lèi)別范圍內(nèi),只要用戶嚴(yán)格遵守產(chǎn)品使用規(guī)則,產(chǎn)品就能達(dá)到可靠的防爆效果。

       Because the product uses The explosion-proof special structure, The product fully meets the use in dIIBT4 To dIICT6ibBT4iaIICT6 Explosion proof class scope, As long as the user Products in strict compliance with the rules of use, The product can achieve reliable Explosion proof effect.
