pressure transducers / depth gauge

Anybody have an idea where one can get the type of submersible
electronics that can be used to build an electronic depth gauge ?

Dive computers must have them - anybody had a look inside ?

Do a search on google for "pressure transducers".
Then narrow it down. You probably want piezoelectric,
absolute pressure (have a sealed vacuum for reference),
and capable of at least 715K pascal(233 fsw). In addition
it will need temperature compensation - not a problem since
most of the ones that fit the bill already are and also
permit interrogation of the temp sensor...and of course,
water proof. You'll find a number of suppliers.

safe diving,

Yes.
