| Aiming at the problem of seawater conductivity measurement, this paper presents a seawater conductivity measurement method
based on magnetic coupling resonance technology, analyzes the influence of seawater eddy current on the magnetic coupling resonance
system from different angles, and verifies the amplification effect of resonance on magnetic field and eddy current by using simulation
software. Taking the two parameters of phase difference and virtual value as the measurement objects, an underwater magnetic coupling
conductivity measurement system is built for experimental research. The influence of seawater conductivity change on the system and the
conductivity measurement effect are compared. The experimental results show that it is feasible to use the magnetic coupling resonance
technology to measure the conductivity of seawater by measuring the phase difference or the effective value of voltage. |
