in pressure transducer designs. This
linear diaphragm pattern has 4 strain
gages mounted onto a single carrier.
The strain gages in the center will go
into tension, and the outer 2 will go
into compression. In the pressure
transducer design, a diaphragm is
clamped around the outer edge, and
subjected to a uniform pressure. Near
the center of the diaphragm the radial
and tangential strains will be positive,
and will be nearly equal. The radial
strain decreases and becomes negative
as you move away from the center
toward the outer edge. Midway between
the center and the outer edge the strain
is at its lowest and the leads/solder

pads are located in this low stress area.
In this pattern, there are 2 half-bridges.
Each half-bridge has a common
lead/solder pad. The pattern has been
enlarged to show the detail. The strain
gages and terminal pads have been
numbered and labeled. The corners of
the Wheatstone bridge have been left
