PRECISION STRAIN GAGE

ROSETTE STRAIN GAGES 0/45/90° AND 0/60/120°
RECTANGULAR AND DELTA, 3 ELEMENT

OMEGA®offers planar and stacked
rosettes. Planar rosettes have all 3
strain gage elements in one plane.
Stacked rosettes have the 3 strain gage
elements stacked one on top of the
other. Consider the difference when you
make your strain gage selection. Planar
rosettes have some advantages over

stacked rosettes. Planar rosettes tend
to be thinner and more flexible. They
can be used on curved surfaces and
conform better to the irregular surfaces.
Reinforcement effects of planar gages
are minimized. Planar rosettes have
superior heat dissipation capability,
and better stability. Stacked rosettes are
