Description

一种结露系统及其露点仪 技术领域
本发明涉及结露测量技术领域，更具体地，涉及一种结露系统及其露点仪。
 背景技术
在天然气、冶金、卫生检疫、含有有毒腐蚀性气体等作业环境中，气体中的水蒸气对作业产生重要的影响。而目前常常通过露点仪来检测气体中水蒸气的露点温度，从而间接测量气体中的湿度。
露点仪根据所使用的冷却方法和检测控制方法，可以分为多种类型。露点仪可利用热电制冷器(Peltier元件) 冷却露层传感器，从而使气体中的水蒸气在露层传感器上发生冷凝，产生露或霜，同时将经接收器采集的信号通过自动控制电路使露层传感器上的露或霜与气体中的水蒸气呈相平衡状态，再用温度计准确测量露层传感器的温度，即露或霜层的温度，从而获得气体的露点温度，也从而间接测量得气体中的湿度。露层传感器包括镜面及发光管、接收管或声表面波器件等元器件。
气体的露点温度是在等压的条件下使气体中水蒸气冷却至凝聚相出现，再通过控制露层传感器露层的温度，使气体中的水蒸气与水或冰的平展表面呈热力学相平衡状态，此时露层的温度即为气体的露点温度。
