| The detection structure of type inductive conductivity sensor (TICS) is not exposed, which can avoid the corrosion of core coil and improve the stability of seawater conductivity detection. However, the relative permeability of the magnetic core of inductive conductivity sensor is not only affected by external temperature and pressure, but also attenuates greatly with the increase of working frequency, resulting in a low output signal and reduced resolution. Firstly, this paper analyzes the physical structure parameters and input signal parameters of the induction probe theoretically. Then, the induction probe is customized according to the structural parameters of theoretical analysis. Finally, through experimental demonstration, the selection basis of structural parameters and working signal parameters of the probe is obtained, which can improve the accuracy and resolution of output signal better. |
