摘要
激励电流源性能的好坏直接影响传感器输出的误差。本文通过实验的方法对阻抗含水率计激励源电路的带载能力,频带以及波形等特性进行了研究和分析。实验结果表明:阻抗含水率计的激励源带载能力与输出电流有关,输出电流越大,带载能力越小,输出电流越小,带载能力越大;阻抗激励源带载峰值与电流成乘幂的关系;激励源电路的频带为10Hz～100kHz;激励源波形的变化对输出电流没有影响。
The output of the impedance sensor is directly affected by the capacity of the sensor's source.So experiments on the sensor's source are made for researching on the load capacity,frequency band and waveform influence.The result shows that:the load capacity is relative with the output current,the higher the outflow of electricity is,the lower the load capacity is,and the larger the output current is,the lower capacity the load has;the relationships between the current and the load capacity is powerful;The frequency bandwidth is ranging from 10 Hz to 100 kHz;the waveform makes no difference on the output.
