摘要
介绍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时,信号不稳定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。
The constant current source exciting scale is introduced. This kind of the scale overcomes shortcoming of the traditional scale based on the constant voltage exciting： the accuracy degraded with the transmitting distance extended. This scale also has lower temperature coefficient than that of constant current source scale.
