I used to use home-made clip-gauges when I worked in the structural integrity field. Those were just a bent bit of clock spring with strain gauges bonded on, but could be used to measure sub-micron displacement on a 20mm gauge length.This was using proto-board and an Op-amp. Dedicated strain gauge amps are available with 24 bit resolution and 50kHz sampling, for a price. https://www.ni.com/en-us/shop/select/c-series-strain-bridge-input-module?modelId=122190 -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
