For under $5 you can buy a hand scale for luggage. I use it for all sorts of things like weigh propane bottles to see how much is left.
Also, don't poke the pressure vessel ... I had 2 PET kegs fail - one popped the valve assembly as I was connecting it, and I was lucky my face was not straight above ...
The're also the risk of adding something that can't be properly sterilized ... with "interesting" results
There has to be something better than shoving something into the keg. Remember your comments about taste and sterility? And while WiFi might make it into that crude Faraday cage, It would also be a PITA when you change the keg.
Bathroom load cells are actually very stable. I have been using one for forty years with no noticeable drift.
Fermentation vessels can be far worse. Yeast actually accelerate under pressure. So if you pitch yeast into sugar and seal it. It almost certainly WILL explode violently. This occurs far more often than you would think. Just with bottles and priming sugar. Either too much priming sugar or not letting the primary fermentation complete and it can produce enough pressure to shatter glass bottles if they capped tight enough.
Trouble... Finding a pressure transducer/load cell which will happily take a 25Kg load 24/7 for a month.
I don't quite understand why the load cells from a bathroom scale would not fit the bill?
In real life absolutely elasticity is not present.
If you constantly stand on the scales, you will become heavier.

When we install sensors for legs at industrial facilities, we sell kettlebells in a set so that the staff periodically calibrates.
Or install reset line to zero on the scales according to the void sensor if it possible.
I do not know the exact data, not involved in this process, but according to colleagues, there is information that the readings of the scales lose about 1% per winter storage of grain - they do not return to zerro after released.

This makes sense. So paulca would have to periodically reset the zero or recalibrate, the same as would be necessary with the elastic bumper idea.
