Is it so difficult to have a sensibly smaller sensor than today?
Theoretically speaking: If it is custom made, we can try optimize for a
small size. In principle the size depends
* on the parts that need to be covered by the housing (piezo-sensor,
electronic, battery, connector, ..)
* the pressure to resist on
* the material used (brass)
* the manufactoring process (turning machine, miller, etc).
I think we can minimise the size and give it a shape that fits better to
an application like diving in caves.
Using industry sensors needs probably more space, we use that pressure
transmitter at the moment;

We prepare a dive test for the next 2 month.
Do you plan to add a O2 sensor monitor?
Yes.
We made a proof of concept for an old military O2-rebreather (RG-UF).
The electrical part is easy the do. The mechanical parts depends on the
application.

Did you see the MSG3500 from the same Swiss manufacturer:

This seems to be specifically for scuba applications already with
the correct port for first stage fitting.
Don't know it, we will check.
Too bad I cannot find a dealer/price quote.
Let's first check if applicable, then ask for the price.
