Hi!
I have bought some strain gauge rosettes like those in the figure.


In the attached datasheet there are two values of transverse sensitivity.


Why? What does it mean?
I think because there are two measuring grids. So if I apply a tensile force the two transverse sensitivities are referred to them. Precisely, if I apply a vertical tensile force the grid to the left is characterized by 0.3% of transverse sensitivity and the grid at right by 1.1%.
Is it correct? I don't know...

 

Please upload the appropriate file size, I already compressed the second graphic, thank you.

 

The transverse sensitivity refers to unwanted signal generated as a result in a direction perpendicular to the maina axis ie transverse.

Here is a manufacturer's pdf on the subject.
