| 摘 要： | 文章着重介绍了基于恒流源激励的远距离高精度电子秤,这种电子秤克服了基于恒压源激励的电子秤在远距离传输信号的时候,信号不稳度而造成的精度下降问题,同时实践证明基于恒流源激励的电子秤在温度系数上也低于基于恒压源的电子秤.

| Abstract: | The paper introduces theelectronic weighing system excited by the constant source and with high accuracy and telecontrol.This system overcomes the shortages of the traditional weighing system excited by the constant voltage source.The accuracy of the later degrades as its unsteady signal with the transmitting distance extends.It has shown in practice that the new system also has the advantage of low temperature coefficient. |

| Keywords: | Electronic weighing system Constant current source Constant voltage source Temperature coefficient |
