标定方法对称重传感器标定的影响

Influence of Calibrating Method on Weighing Sensor

称重传感器标定可采用万用表和虚拟仪器(在线)两种方法,实验分别用这两种方法测量数据,使用Matlab进行最小二乘曲线拟合,对拟合结果进行比较,验证了不同标定方式对标定结果的影响,并对传感器标定提出建议。

To calibrate a weighing sensor has two methods, one is using multimeter, other is using virtual instrument （on-line）. Experiment use these methods to cahbrate the weighing sensor, and fits the date in a least squares sense use Matlab. The fitting result are compared, the influence of different methods to calibrate are validated, and to propose calibrating sensor.
