Thank you Brant,

I saw vibration measuring project in Elector (well... 20 years old).
There was extra weight in role of changing nelinear piezo characteristic
(I suppose) and moving peak in region of interest or widening it. Today
one can do this in software, like you do.
I like to see physical realization of sensor (xyz) and mounting solution
(I already have piezo - 10 peaces, without enclosure). It will be very
good if you have some gif or jpg pictures.
I want to monitor ball valves in slurry pump (80bar).

Thank you for links (I will download later).

Regards,
Pedja
