选择合适的防水透气组件所要做的并不单单是从防水透气阀的目录中选择一个产品，而是需要综合考虑产品的材料、尺寸、膜的开孔率、厚度、孔径等多种因素。因此应根据具体的传感器要求（如大透气量、防护等级、工作温度、外壳的尺寸等）进行设计制造。

传感器的防护等级（IP67）表示防水透气组件必须能够承受对水进行防护的量，而周围环境的恶劣程度也会影响防水透气组件在传感器外壳上安装的位置和方法。

在防水透气组件的设计过程中，往往只关注组件的防水性、透气性以及环境适应性，忽略了实际工作条件下传感器的自然凝露带来的问题。如果在传感器设计上没有考虑到防凝露的措施或所采取的措施不当，就会导致传感器内部有水汽凝结在电路板上，导致电路漏电增加或短路，严重时甚至会导致电路烧毁；凝露还可能造成传感器的绝缘性能下降、漏电增大，甚至会出现飞弧和击穿等现象，造成整个系统的损伤。

经过理论分析及大量试验结果表明：安装防水透气组件的压力传感器，内部湿度会跟随外部迅速变化，在凝露情况不可避免的情况下，防水透气组件会迅速排出凝露，将凝露的量控制在比较小的范围不影响传感器性能；而不安装防水透气组件的压力传感器由于凝露的长期累积并不外排会导致电路短路，对压力传感器的可靠性带来巨大风险。RS-422/485 scTew termination includeASCIISerial Port Isolation
