K6050便携式气体浓度分析仪
特性把昂贵的停机时间缩到zui短耐用、便携吹扫气用量zui少可靠,容易使用IP67防风雨外壳应用气体生产行业或钢铁行业氩气浓度分析或使用在发电站在充氢或再充空气之前,为避免产生可燃混合气,有必要使用一种惰性介质气体。二氧化碳(CO2)是zui常用的惰性介质气体。这样,在给涡沦发电机充气时,先用CO2把空气从系统中吹扫出来,然后再用氢气把CO2吹扫出来。
发电机吹扫气监测仪可以监测充氢、空气再充过程的所有阶段,也可检测正常运行过程中的氢气纯度。也可适用于电力行业高压开关六氟化硫浓度检测。
操作原理
在构造上,热导计由两个室构成,每个室都有一个相同的热导传感器。其中一个室是密封的,里面充满参比气,另一个室接收样气。二次表内的微处理器电路把参比气与样气的热导系数的差值转化为浓度值。
该系统的内在的稳定性和它几近*的温度补偿功能使得这种仪表成为当今市场上zui精确的仪表之一。
系统描述
仪表封装在坚固的防水外壳里。它使用充电电池供电,可以连续使用6个小时。如要连续使用仪表,把它连接到交流电电源即可。
使用内置泵、针阀和流量计来控制监测发电机气体过程中通过分析仪的样气。
K6050将显示如下量程之一,
用户可以通过键板选择要显示的量程:
空气中0~100%氩气或空气中0–100%的CO2
CO2中0–100%的H2空气中90–100%H2
大LCD显示检测浓度,还显示使用菜单对仪表进行设定和校验时所出现的信息和提示。
