I’m designing an equipment that will be in a rural area exposed to heavy rains. I already got an IP67 rated enclosure with IP67 connectors and it’s working as expected.
I need to measure the ambient pressure so I found this sensor 13C5000PA4K (datasheet:http://www.kynix.com/uploadfiles/pdf/13C5000PA4K.pdf)for the task. The issue is, I need to drill a hole for the pressure inside the enclosure be the same as the pressure outside. But this hole will be an entrance for water during heavy rains. I found this image from a mesh used in the iPhone 7 that allows air to pass through but not water:
But I couldn’t find the name of this meshes or something similar. I’m thinking that I could protect the hole with a mesh like that to prevent water entrance.
Does this meshes has any special name? What other approach is used to measure ambient pressure in this conditions?
