Has anybody a prize estimate (and reference)
for pressure sensors to measure depth
in water for the range 0-50 m (10-60 N/cm2)
and precision 10 cm (0.1 N/cm2) ?

Try Omega Engineering, www.omega.com, probably cost around $800 for one
that won't be thrashed by saltwater.

There are dozens of other manufacturers. Did you try doing a web search?

Note that atmospheric pressure variation can introduce perceived
differences of around +/- 50cm if not compensated for.

My sensors are assumed to go up and down from the surface
rather regularly :-)

By the way: I did not find such pressure sensors for much less than
EURO 500 each. I need an "array" of such sensors (10-20 sensors),
and it would be preferable that are cheap and small (and to be
read off via some kind of "data bus" - i.e. one cable for all
to the logger).
