Andrew,

I know from firsthand experience that mechanical pressure gauges with a
maximum reading of 30,000 PSI are known to mankind; I imagine that they are
also available for higher pressure applications.  If nothing else, check out
an oxyacetylene outfit.  You will find an oxygen tank gauge which pegs out at
4000 PSI.
