固定法兰防爆热电阻WZP-441固定法兰防爆热电阻上海天康仪表有限公司
【产品应用】
固定法兰防爆热电阻WZP-441固定法兰防爆热电阻通常和显示仪表、记录仪表、电子计算机等配套使用。直接测量各种生现场存在碳氢化合物等物的-200℃~500℃范围内液体、蒸汽和气体介质以及固体表面温度。
【工作原理】
固定法兰防爆热电阻WZP-441固定法兰防爆热电阻是利用物间隙隔爆原理,设计具有足够强度的接线盒等部件,将所有会产生火花、电弧和危险温度的零部件都密封在接线盒腔内,当腔内发生时,能通过接合面间隙熄火和冷却,使后的火焰和温度传不到腔外,从而进行隔爆。
【特点】
1.压簧式感温元件,抗振性能好;
2.测量准确度高;
3.毋须补偿导线,节省费用;
4.进口薄膜电阻元件,性能可靠稳定;
常温绝缘电阻:防爆热电阻在环境温度为15~35℃,相对湿度不大于80%,试验电压为10~100V(直流)电极与外套管之间的绝缘电阻≥100MΩ
防爆等级:防爆热电偶的防爆等级按其使用于性气体混合物***大试验安全间隙分为A、B、C三级
Ⅰ类——煤矿井下用电气设备
Ⅱ类——工厂用电气设备
A 0.9≤MESG
B 0.5<MESG<0.9
C MESG≤0.5
