The characteristics of the 2 mm strain gauge were nonlinear up to 5 MPa stress values, which corresponded to about 0.300 kg mass.
If strain gauges are used, it is possible to achieve good results with a small amount of measurement points, and the measurement equipment can be set so individual loading components can be scanned directly during flight.
Both the strain gauge and the measuring circuit are, in the physical sense, passive components.
