Crazy Idea #35
Is there a pressure switch (10psi specifically) that doesn't require reference to atmospheric...Ten psi is the "full" point when my ballast tanks should stop filling. Rather then using a float switch , I am thinking of an in line pressure switch to stop the pumps-it would be simpler. Is there such a thing? I guess it would have to be a sealed bellows that compresses air (or a gas) within the chamber. I believe its called a "sealed" (reference) pressure switch.
