A Novel Precision Strain Measuring Circuit with Double-Channel Method
To improve the accuracy of strain, the design method and technology based on the theory of double-channel parametric measurement is proposed. At last, the measuring circuit with linear conversion function is designed. Based on the theory, a measuring system is developed. The practical experimentation indicates that the theory and technology are right, and the accuracy, stability, anti-interference and reliability are excellent.
