Take a look at the latest KWIK circuit FAQ from Tim Green. Here Tim takes you through a step by step guide on how to address the design challenges associated with full bridge strain gauge sensors. The details captured in the KWIK circuit FAQ not only talk to the generic formula associated but there is also a model that can be used in LTspice making it easy to simulate and understand the associated performance, which makes it very easy to tune and scale to different strain gauge applications.
