简式称重传感器电桥测量中的非平衡误差分析

The analysis of the Unbalanced Error for Measurement by Bridge of Cylindrical Weight Sensor

在称重传感器的测量中，大部分是在非平衡状态下进行的。因此，在电压源供电的情况下，电桥支路中桥臂电阻的变化即引起支路中电流的变化。本文即对筒式称重传感器由于这种变化引起的附加误差进行了探讨，定量地指出这种误差的大小、特点以及解决办法。

As the measurment by cylindrical weight sensor is carried out mostly in the unbalanced condition, the variety of resistance in the arm of electric bridge causes the vedety of cunrent in it in the condihon of power on. The error caused by this change is discussed,defined in its amount and specified in its specification and compensation solution in the article.
