Design and build your own transducers.
These full bridge strain gages might be
used to design transducers for beams
that have a contraflexure point.
Contraflexure is defined as a point in a
structure where bending occurs in
opposite directions. This may also be
described as a reversed bending beam,
or a double bending beam. The 4 grids
are linear, all in the same direction.
Look up the modulus of elasticity and
the yield strength of your material, and
design the 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 strain gage temperature characteristics. You may use these full
bridge strain gages for bending strain
applications where only one side of the
beam is available for strain gage
installation. These gages are easy to
work with as the carrier piece has all
4 strain gages for fast and easy
installation. Having one carrier with
multiple strain gages offers several
advantages. Alignment of the 4 strain
gages with respect to each other is
already done. Some of the strain gages
share common ribbon leads or Solder
Padss which saves wiring steps and
valuable time. The corners of the
Wheatstone bridge at the signal output
have been left open so that sensor performance can be tested and
improved. Zero temperature
compensation resistors and zero
balance compensation resistors can be
easily added into the open corners of
the Wheatstone bridge circuit. An extra
bondable terminal pad can be placed at
the open corner so that the appropriate
resistors can be wired in. Or you can
simply connect your 4 leads
(+Excitation, -Excitation, +Signal,
-Signal) and jumper the signal leads
together as needed to complete the
Wheatstone bridge. Power up your
transducer, and calibrate it with a known
applied load.
