Quickly and easily design and build your
own transducer for bending or axial
strain applications where only one side
of the beam is available for strain gage
installation. Look up the Modulus of
Elasticity and the Yield Strength of your
material, and design your spring
element so that you will be working in
the linear portion of the stress-strain
curve. For best results use stainless
steel or aluminum and match the
material to the strain gage temperature
characteristics. Install one full bridge, as
the one carrier piece has all 4 strain
gages. Having one carrier with multiple
strain gages offers several advantages.
Alignment of the 4 strain gages with
respect to each other has already done
for you. Strain gages share common
ribbon leads or solder pads which saves
wiring steps and valuable time. Simply,
position the bondable terminal pad
close by, and connect your 4 leads
(+Excitation, -Excitation, +Signal,
-Signal) to the already completed full
Wheatstone bridge. Power up your
transducer, and calibrate it with a known
applied load. The full bridge has 2 fully
active strain gages in the principal
stress direction and 2 strain gages that
will see the effect of Poisson’s Ratio.
The full Wheatstone bridge tends to
cancel thermal and off-axis errors.
SGT-3G/350-FB** has 5 terminals,
which means it has an open corner at
the signal terminals, for addition of zero
temperature compensation, and zero
balance compensation resistors. All of
the other full bridge gages on this page
have 4 terminals.
