What about something like this then?
These guys make pressure transducers/transmitters for
boilers, which operate in a nastier environment than you plan on putting your
ROV in.
Assuming your ROV is operated on a cable you could get
the matching gauge mounted on your instrument panel and again mark up the face
to read in depth instead of PSI. A call to a gauge manufacturer wouldn't be a
waste of time here.

Preasure Gauge
I need the gauge to report back electronicly so
an analog gauge would be good only if I had a video camera that looked at it
constantly.

Subject: RE: [PSUBS-MAILIST] Preasure
Gauge
I'm sure this a subject that has come up many times
however I'm new at this. Could you not simply use a mechanical pressure
gauge and recalibrate the dial to read in feet instead of PSI? I have a
mechanical pressure gauge on my old Jeep that uses a small tube to the oil
pump to read the pressure. The tube is always full of oil and it doesn't
foul the gauge so I can't imagine that water would either. Obviously an oil
pressure gauge from an automobile wouldn't work because it only reads uo to
about 80 PSI but with some research I'm sure you can find a gauge that reads
up to whatever PSI you expect to encounter and
beyond.
I'm looking to make myself some sort of
preasure gauge so I can calculate depth, but the best Idea I can come up
with is to embed a Preasure sensor in a ball of silicon and mount it to the
outside of my preasure hull, I'm thinking that the silicon will transfer
preasure to the sensor evenly as well as protect it from water damage. The
biggest problem with that would be the wires coming out of the silicon ball
causing rippage if any stress was put on them, thus allowing water in
however minute amount to get to the sensor, so I'd have to make some sort of
cradle for it so it can't move... maybe epoxy it onto a machine brass
craddle that can be mounted to the preasure hull which I can then run the
wires through so I can connect the Preasure sensor to the MC this way I can
avoid loose wires. Another problem is would the silicon transfer the
preasure so I could get an accurate reading.
Am I over thinking this, is there some simple
solution I'm over looking?
Thanks
