I am currently working on my bachelor project and I might have been a bit overly ambitious. I am trying to make an automatic circuit for testing the integrity of sterile filters.
In order to do that I need to find a way to regulate the air pressure from my source (which is 4.8bar) so that it increases gradually. I also need to increase the pressure to 10-15bar and release it after I do measurements I need.
After looking at few posts about projects with controlled air pressure I think I could use some magnetic valves, pressure sensors and an air compressor. The main issue is those projects used significantly lower pressure values so I don't know if that would work for me.
