数据采集中减少传感器非线性影响的方法

The Method for Decreasing Nonlinear Effect of Transducer in Data Acquisition

本文提出了用折线拟合传感器特性曲线的方法和由查表得到特殊点输出值的方法,这二者相结合,可以把非线性误差减少到最低限度。

In this paper, a joint approach combining the fitting of the fold line with the transducer characteristic curve and the read ing of the speciall point output from the checking list is introduced, by which the nonlinear error can be reduced to the lowest limit.
