The constant current strain gauge bridge
Abstract
A simplified analysis is used to develop expressions for the output of the commonly used strain gauge bridge configurations with constant current excitation. Expressions for initial offset compensation, shunt calibration and the influence of lead resistance are developed. Consideration is given to some means for error correction.
