传感器防水透气材料和过滤器

优质组件可最大限度提高传感器应用的性能

利用尖端技术保护和增强传感器性能

全球制造商信赖 Porex 的尖端技术，其性能远超竞争对手。POREX® 材料可最大程度提升众多传感器应用的性能，包括气体吸收、透气、扩散以及电解质的储存和芯吸。

我们为传感器制造商提供的定制解决方案可以根据特定的应用或设备进行定制，并与许多制造流程无缝集成。

气体吸收过滤器

采用 Porex 的气体吸收材料定制的过滤器旨在针对可能导致传感器读数错误或导致电池本身过早退化的特定气体。

我们的气体吸收过滤器专为您的传感器设备而设计，具有以下特点：

Gas absorbing filters for industrial sensors

定制气体传感器吸收过滤的选项

主要特点和优点

可有效捕获多种可能对传感器有害的气体，包括硫化氢（H2S）、二氧化硫(SO2)、六甲基二硅氮烷(HMDS)、有机物、酒精等。
吸收大量有害气体 –与竞争材料相比，POREX® 过滤器每单位体积可吸收更多的有害气体，使用寿命比竞争产品更长。
材料安全—POREX 过滤器采用可安全使用的试剂制成，不同于含有有毒铅成分的竞争产品。

透气防水介质和扩散层

平衡压力并排斥污染物

POREX Virtek® IP 等级 PTFE 透气膜快速扩散气体，同时有效防尘、防水及其他污染物。我们的保护透气膜专为电子设备设计，具有以下特点：

定制传感器透气防水和扩散层的选项

主要特点和优点

实现快速检测—允许目标气体更快地扩散，从而实现更快的检测
平衡压力—减少压力积聚并让热量从电子外壳中逸出，因为透气结构充当了泄压阀的作用，保护外壳密封免于过早失效。
防止污染—通过防水、防汗、防油和其他液体来保护内部组件。
