So avoiding heat variation which is increasing the error or it must be compensated. And will be a voltage variation for an acceleration variation. Not easy for an accurate measurement. And good only for great earthquakes where anyway does not care, you'll don't be allive to monitorise the signal... cheers, Vasile > > resistive flex strip set up the same way.
