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

We prepare a dive test for the next 2 month. <br>

Do you plan to add a O2 sensor monitor?</p>
</blockquote>
Yes.<br>
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.<br>

Did you see the MSG3500 from the same Swiss manufacturer: <a

This seems to be specifically for scuba applications already
with the correct port for first stage fitting.<br>

Don't know it, we will check.<br>

Let's first check if applicable, then ask for the price.<br>
