Consistency calibration method for multi-sensor
Haiyong Liu · China Measurement & Test · 2012
For solving the problem of the adjacent region interaction of positions error calibration and regulation for systems with multiple weighting sensors,a calibration technique was proposed,whose main principle was normalizing the output for multiple-sensor applications.By measuring the output-voltage of each sensor with the same excitation,and calculating the calibration value difference between the loaded and no-loaded,the bias resistor was obtained through normalization method.The result indicates that the new method could reduce the positions error under 1%,and reduce the blindness of the modification process.
