The basic principle of strain electronic measurement technique is introduced. The circuit of strain measurement with bonding resistance is analyzed and designed. In the strain expression deduced in this paper, nonlinear error is eliminated and error caused by wire resistance is modified, furthermore material Poisson effect is considered, so measurement precision is improved greatly. |
