RE: [PSUBS-MAILIST] pressure gauge

This is one that I put together for inside to make sure I don’t build pressure inside and another outside they have feet of H2O, the ball is a solder sucker from radio shack and swagelock fittings filled with mineral oil ,I have check them against a dive computer down to fifty feet and seem to be working I changed it back to psi and was right on the money with my dive computer, can’t wait to check them at 1000 feet

Hi David,

That is so nineteenth centuary; we are now in the 21st.

I bought mine from Grainger in the U.S.A.

I think people fit them with an oil filled balloon on the outer side of the hull so seawater doesn't get in to them.

Someone else might comment on that.

Alan

I got one!
 
   If I took an air tank and lobbed off the bottom to it and placed it such that the lower part was down deep in the water within an ambient submarine. A small metal tube was then attached to the upper or output end and ran up to a pressure gage. Would this show pressure in psi as can be converted to the depth of the sub?
