溫度變送器隔爆熱電偶

帶溫度變送器隔爆熱電偶:WRNB-140、WRNB-140G

1、應(yīng)用

      通常和顯示儀表、記錄儀表、電子計(jì)算機(jī)等配套使用,輸出4-20mA,直接測(cè)量生產(chǎn)現(xiàn)場(chǎng)存在碳氯化合物等爆炸物的-200℃-1300℃范圍內(nèi)液體、蒸汽的氣體 質(zhì)以及固體表面溫度。

2、特點(diǎn)
   二線制輸出4-20mA,抗干擾能力強(qiáng);
   節(jié)省補(bǔ)償導(dǎo)線及安裝溫度變送器費(fèi)用;
   安全可靠,使用壽命長(zhǎng);
   冷端溫度自動(dòng)補(bǔ)償,非線性校正電路 ;
 
3、工作原理
    防爆熱電偶利用間隙隔爆原理,當(dāng)腔內(nèi)發(fā)生爆炸時(shí),能通過接合面間隙熄火和冷卻,使爆炸后的火焰全溫度傳不到腔外,從而進(jìn)行防爆。
    熱電偶(熱電阻)產(chǎn)生的熱電勢(shì)(電阻)經(jīng)過溫度變送器的電橋產(chǎn)生不平衡信號(hào),經(jīng)放大后轉(zhuǎn)換成為4-20mA的直流電信號(hào)給工作儀表,工作儀表便顯示出所對(duì)應(yīng)的溫度值。
 
4、主要技術(shù)參數(shù)
