Mechanism Analysis and Verification of Seawater Conductivity Measurement Based on Magnetic Resonance
This paper focuses on measuring conductivity in low-conductivity seawater environments such as saltwater,and focuses on researching seawater conductivity measurement methods based on magnetic resonance systems.The influence of seawater eddy currents on coupled coil systems is analyzed from different perspectives.A seawater equivalent circuit model for this problem is proposed,and the influence of seawater conductivity changes on the self-inductance,mutual inductance,and resistance parameters of coils is analyzed.The original model is parameterized and expanded,and relevant theories and formulas suitable for coil parameter analysis are derived.The influence mechanism of seawater conductivity changes on the system was verified through simulation and experiments.The results showed that seawater conductivity mainly affects the electric field around the coil,thereby changing the equivalent resistance of the coil and affecting the measured voltage parameters of the system.This theory can support the measurement of conductivity in low-conductivity media such as seawater.
