一、產(chǎn)品簡(jiǎn)介 Product introduction
WZP系列工業(yè)用隔爆熱電阻是一種溫度傳感器。在工業(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。
WZP seriesindustrial flameproof thermal resistance is a kind of temperature sensor. It iswidely used in the industrial automatic control system. Through the temperaturesensor, the temperature parameters of the control object can be changed intoelectrical signals and transmitted to the display, recording and regulatinginstruments to detect, adjust and control the system.
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阻非常不安全,極易引起環(huán)境氣體爆炸。因此,在這些場(chǎng)合必須使用隔爆熱電阻作溫度傳感器。本公司生產(chǎn)的隔爆熱電阻產(chǎn)品適用dIIBT4~dIICT6溫度組別區(qū)間內(nèi)具有爆炸性氣體危險(xiǎn)的場(chǎng)所內(nèi)。
Productionsite of a chemical plant is often accompanied by various flammable, explosiveand other chemical gases and vapors. If ordinary thermal resistors are used, itis very unsafe, and it is very easy to cause environmental gas explosion. therefore,flameproof thermal resistance must be used as temperature sensor in theseoccasions. the flameproof thermal resistance products produced by the companyare applicable to places with explosive gas hazards within the temperaturegroup of dIIBT4~dIICT6.
本公司生產(chǎn)的隔爆熱電阻采用引進(jìn)元件作感溫元件,其技術(shù)性能符合ZBY301-85工業(yè)熱電阻技術(shù)條件和分度表。同時(shí)符合爆炸性環(huán)境用隔爆電氣設(shè)備通用要求GB3836.1~2010、GB3836.2-2010標(biāo)準(zhǔn)。防爆證編號(hào): CNEx19.4448X
Flameproof thermal resistance producedby the company adopts imported components as temperature sensing elements, andits technical performance meets the technical conditions and graduation tableof zby301-85 industrial thermal resistance. At the same time, it meets thegeneral requirements for flameproof electrical equipment for explosiveatmospheres GB3836.1~2010 and GB3836.2-2010 standards. Explosion proofCertificate No.: CNEx19.4448X
二、工作原理 Operational principle
隔爆或本安熱電阻與裝配式熱電阻的結(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)上采用隔爆特殊結(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)定性均符合國(guó)家隔爆標(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 Thermalresistance And the assembly type Thermal resistance Structure, The same basicprinciples,The difference is, Flameproof Or intrinsically safe product Junctionbox (shell) In the design of the Explosion proof special structure, Wiring boxfor high strength aluminum alloy die-casting and, And has sufficient internalspace, Wall thickness and mechanical strength, The rubber sealing ring Thermalstability Are in line with national standards for explosion proof. So, When thewiring inside the box Explosive gas mixture When the explosion, The innerpressure Will not damage the junction box, The resulting Heat energy can not beoutward diffusion of detonation.
由于產(chǎn)品采用上述隔爆特殊結(jié)構(gòu),使產(chǎn)品符合使用在dIIBT4至dIICT6、ibBT4、iaIICT6隔爆類(lèi)別范圍內(nèi),只要用戶(hù)嚴(yán)格遵守產(chǎn)品使用規(guī)則,產(chǎn)品就能達(dá)到可靠的隔爆效果。
Because the product uses Theexplosion-proof special structure, The product fully meets the use in dIIBT4 TodIICT6、ibBT4、iaIICT6Explosion proof class scope, As long as the user Products in strict compliancewith the rules of use, The product can achieve reliable Explosion proof effect.
