摘要
基于双极性脉冲电压技术,设计了一种新型电导测量仪。它不仅能够削弱直流激励模式下介质的极化现象,还能避免传统交流激励模式下所必须的滤波器等复杂信号调理环节,从而简化了电路结构。同时为了提高测量精度,引入了线性校正模型。实验表明所研制的电导测量仪是成功的。
A new electrical conductance measurement instrument based on bi-directional pulsed voltage technique is proposed.Polarization effects of the media are eliminated.The complex and time-consuming filters are not needed.Thus,the measurement circuitry is simplified and has high speed capability.Linear calibration models are introduced to improve the accuracy of the instrument.Experimental results show that the developed instrument is effective.
