Bending Poisson Full
Bridge (FBPoisson)
In applications where there is no equal strain of opposite sign as there is for
the beam in Figure 4-14, Poisson strain can be measured by mounting the
strain gages at right angles on the specimen. Mounting the gages in this
manner is known as a Poisson arrangement and is represented in Figure
4-15. With a Poisson arrangement, the sensitivity is not as great as with the
bending full bridge. However, since the gages are adjacent legs of the
Wheatstone Bridge circuit, complete temperature compensation is achieved.
