I recently got interested in getting a shop press. I see some presses come with a pressure gauge and wondered why is a gauge necessary and how is it used? Thanks Paul

Commercial ones show tonnage of force.
This of course is a predetermined multiple of the hydralic pressure and the area of the piston

Mine is attached to the top of the cylinder, so reads pressure directly off the hydraulic fluid. I find it useful for bending and straightening. If you know what pressure you were at and need just a little more or want to go back the other way the same amount it will get you closer than a wild guess. With hydraulics there is no feel like on an arbor press so the only way you can tell what it's doing is a gauge.

Although not a technical answer, my air over hydraulic pump and hydraulic press cylinder is equipped with a pressure gauge. When pressing, I check the gauge...when it gets too high I close my eyes, pucker my tailpipe and pray to higher powers...that's what I use the gauge for...

That's one way to increase the capacity of your arbor press!! :D :D

I also like the carrying capacity (though I'm not sure the casters are up to it) and fact that pressure chart is hidden behind I beam. LOL
