Options 0701071 - Combined Bridge ConfigurationsStrain Gauge EquationsRecall that we developed an equation for strain in terms of the input and outputvoltages of a '/4 bridge circuit. The assemblies can, of course, be used for '/z andfull bridge measurements and a combination of bridges (10 maximum) can be inputto a single assembly.Although the assemblies are specifically designed for use with bonded resistancestrain gauges, they can also be used with any resistive transducer, such as RTDsand 3-element rosettes. For these reasons, Figure 123 (at the end of this section)shows equations for determining strain for strain gauge bridges, biaxial stress stateequations, rosette equations, wire resistances and selected materials properties.Artisan Technology Group - Quality Instrumentation ...
