详情介绍

带温度变送器隔爆热电偶:WRNB-140、WRNB-140G

1、应用

      通常和显示仪表、记录仪表、电子计算机等配套使用,输出4-20mA,直接测量生产现场存在碳氯化合物等爆炸物的-200℃-1300℃范围内液体、蒸汽的气体 质以及固体表面温度。

2、特点
   二线制输出4-20mA,抗干扰能力强;
   节省补偿导线及安装温度变送器费用;
   安全可靠,使用寿命长;
   冷端温度自动补偿,非线性校正电路 ;
 
3、工作原理
    防爆热电偶利用间隙隔爆原理,当腔内发生爆炸时,能通过接合面间隙熄火和冷却,使爆炸后的火焰全温度传不到腔外,从而进行防爆。
    热电偶(热电阻)产生的热电势(电阻)经过温度变送器的电桥产生不平衡信号,经放大后转换成为4-20mA的直流电信号给工作仪表,工作仪表便显示出所对应的温度值。
