On the block diagram, drag down the arrow on the bottom of the Formula icon to expand
the input/output menu. To change the order of the elements, right click on an element and select
“select input/output”, then click on the input/output desired for the position. Connect the data
output of the DAQ Assistant, and the Numerical Controls for excitation voltage, gage factor and
gain to the corresponding inputs of the Formula. Connect the Numeric Control and Wave Graph
for micro strain to the result output of Formula. Then click on the text under the icon to change
the label to “micro strain”.
In similar ways, internal pressure can be calculated from strain and other properties of the
can. Use Formula to calculate internal pressure based on micro strain results from previous
Formula, inputs from Numeric Controls for material’s modulus of elasticity, material’s Poisson’s
ratio, thickness of the can wall, and diameter of the can. The formula is shown in the figure
below.
