# Strain-gauge bridge sensitivity
# Scope: Small-strain quarter bridge with ideal completion resistors.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

gaugeFactor = 2
strain = 0.001
excitation = 5 V

fractionalResistance := gaugeFactor*strain
bridgeOutput := excitation*fractionalResistance/4 [mV]

check bridge output budget: bridgeOutput <= 5 mV

scenario alternative: gaugeFactor = 1.6
