Thermometers
Flameproof thermal resistance

Flameproof thermal resistance
It is usually used together with display instruments, recording instruments, and computers. 直接测量生产现场存在碳氢化合物等爆炸的0~500℃范围内液体、蒸汽和气体介质以及固体表面温度。 Explosion-proof thermal resistance directly measures the temperature of liquid, steam, gaseous medium and solid surface in the range of 0 ~ 500 ℃ where there are explosions such as hydrocarbons on the production site. zzyfwh.com
Features
1. Spring-loaded temperature sensor with good shock resistance
2.Large measurement range
3.Imported thin film resistance elements, reliable and stable performance

working principle
和装配式热电阻的结构,原理基本相同,所区别的是隔爆型产品的接线盒(外壳)在设计上采用防爆特殊的结构,接线盒用高强度铝合金压铸而成,并具有足够的内部空间、壁厚和机械强度、橡胶密封圈的热稳定性均符合国家防爆标准,所以,当接线盒内部的爆炸性混合气体发生爆炸时,其内压不会破坏接线盒,而由此产生的热能不能向外扩散、传爆。 The structure of the flameproof thermal resistance and the assembled thermal resistance are basically the same. The difference is that the junction box (housing) of the explosion-proof product is designed with a special explosion-proof structure. The junction box is die-cast from high-strength aluminum alloy. It has sufficient internal space, wall thickness and mechanical strength, and the thermal stability of the rubber seal ring meets national explosion-proof standards. Therefore, when the explosive mixed gas inside the junction box explodes, its internal pressure will not damage the junction box, and The resulting thermal energy cannot spread or explode.
