Was the pressure sender screwed into a blind hole where the pressure never changes?
Interesting idea. And it is items like that which make the spoliation arguments even stronger. How can Rossi claim the results to attack IH if he destroys such evidence? In Penon's test plan the pressure gauges would have been outside the container and thus the pipe they fitted in were destroyed and he sent the gauges out of the country never to be seen again.
Where was the temp sensor placed? Out side on the now destroyed plumbing?
