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。 Introduced based on constant current source excitation of long-range high-precision electronic scale, this electronic scale to overcome the constant voltage source based on the long-distance transmission of electronic scales in the signal, the signal instability caused by the decline in accuracy, while practice has proved based on constant Flow-inspired electronic scales are also lower in temperature coefficient than electronic scales based on a constant voltage source.
