摘要
本文提出了用于磁感应方式电导率测量的单通道硬件系统的原理和结构,在此基础上,以NaCl溶液和琼脂为目标,进行了一系列试验,初步评估了场域的敏感性分布,证明了补偿线圈可以有效提高系统的相对灵敏度,试验结果与理论分析的比较证明了试验结果的可靠性。
This paper presents the principle and structure of the hardware used in the single-channel measurement of conductivity in a magnetic induction way. Based on the hardware, a series of experiments are made over saline solution targets and agar targets, the sensitivity distribution are evaluated preliminarily, we proved that a higher relative sensitivity can be obtained by using a back-off coil, reliable conclusions are drawn from the comparison between theoretical analysis and experiment results.
