Thermometers
Flameproof thermocouple

application

通常和显示仪表、记录仪表、电子计算机等配套使用, 隔爆热电偶直接测量生产现场存在碳氢化合物等爆炸的0~1300℃范围内的液体、蒸汽和气体介质以及固体表面温度。 Explosion-proof thermocouples are usually used in conjunction with display instruments, recording instruments, electronic computers, etc. Explosion-proof thermocouples directly measure liquid, steam, gaseous media and solid surface temperatures in the range of 0 to 1300 ° C where hydrocarbons and other explosives are present on the production site. . zzyfwh.com

  特点 Flameproof Thermocouple Features

Multiple explosion-proof forms

Spring-loaded temperature sensor with good anti-vibration performance

Large measuring range

High mechanical strength and good pressure resistance


working principle

Explosion-proof or intrinsically safe thermocouples have the same structure and principle as assembled thermocouples. The difference is that the explosion-proof or intrinsically safe product junction box (enclosure) is designed with a special explosion-proof structure. The junction box is made of high-strength aluminum. The alloy is made of die-casting and has sufficient internal space, wall thickness and mechanical strength. 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 be diffused outward and transmitted.
