Interesting that you want to use a Jeti radio. I have a DC16 and the possibilities are massive.
For your question about the sensor I don’t have a direct solution for Jeti, but for the Brixl radios you can buy a sensor directly at Brixl that works up to 35bar:

Perhaps someone at the Jetiforum can help out with the signals, with a Arduino nano in between you should be able to get it to work.
On the Jetiforum you can ask in English as well:
