Using third party Strain Amplfiers, feeding DC output to NI 1102 multiplexer to increase channel count, has anyone a vi. already?
As I see required events, measure un-strained millivolt value, file, after applying force, measure strained millivolt value, determine difference between strained and unstrained, convert delta millivolts to strain, and present. Using NI strain gage boards is good, if we already had them. They are either 4 or 8 chan/board. Amplifiers we already have along with several NI 1102 multiplexed boards. These allow us 32 strains/board. Calibration can be done by using external shunt with calculated equivalent strain, setting amplifier gain accordingly i.e., 1000ue=1.0 volts. Can eventually arrive at working vi., but if someone has done this and are willing to share, it would be of great benifit. Time is always of the essence.
