Hi,
I am somewhat inexperienced with LabView and would appreciate any guidance y'all could offer.
My goal is to process voltage readings from four 3-wire strain gauges into Labview by means of an NI Elvis board for a super high tech digital scale. As a search on these forums have found (and lots of hours), the signal usually needs to be amplified. Many people choose to use additional USB add-on modules like the 9237. This application is for a design project and our budget is limited--hence the need to only use Labview and an Elvis board.
My problem lies with gaining enough resolution as the signals are inherently noisy and oscillate all over the place. I've tried using filters to get rid of 100 Hz and 55-65 Hz noise. Increasing the order and changing the magnitude doesn't seem to do anything! I've tried changing the orders, combinations, etc. Furthermore, because the signal oscillates, the value that Labview gets at one time instant for the zero is completely different just a few minutes later. This leads to a significant amount of fluctuations in the final weight values.
Any suggestions or help would be most helpful!
Thanks!
