A dual coil eddy current pressure transducer is way more immune to magnetic
field, radiation and noise, but costs $6k instead of the $500 one they have.
It also can go to 580C or so, instead of 85C as this one, in use.

I think it would be interesting to test a similar pressure transducer to the
one that they are using to understand how it operates under a varying magnetic
or electric fields. It may be that local conditions are affecting the
transducer and are indicative of unexpected electric or magnetic conditions in
the reactor. They may be caused by LENR or SPP formation or something
unexpected.

I am glad to see that with 30% pressure swings indicated, the operator
decided to at least wear a face mask. I think I heard that the tube was good
for 1000 psi and they were getting indications of over 600 psi with large
swings. It appeared they did not believe their pressure sensor. I think they
should have a good bullet proof shield around the dog bone.
I would worry about the integrity of an alumina pressure vessel. Is such
material commonly used for pressure containing vessels at high temperatures and
pressures?
It seems they disconnected the pressure sensor at about 2 hrs. and 40 min.
into the test, or at least discontinued the video of the signal. I hope they
keep the pressure data that since it may be real. However, it would appear
that it was correlated with heater power input.

Ya' gotta love the 21st century.
This seems kind of pointless. Why not read the data a week later? Still, it
is fun!
The technical chatter makes it sound like NASA. Impressive!
I wish Arthur Clarke had lived to see this.
