By high-frequency excitation, eddy currents are induced in the fluid and are counter-fields measured with a sensing coil. The coil’s resonance point is used for amplification. The developed prototype is analyzed based on a derived transfer function and FEM simulations. The theory is validated using a prototype implementation. With conducted experiments on a sensor test bench, the characteristics are confirmed and disturbances identified. It is shown that frequencies exist where temperature influence is minimal. This work gives a perspective for a novel sensor to allow seawater conductivity measurement.en2673-459120211MDPIhttps://creativecommons.org/licenses/by/4.0/salinityconductivityinductiveeddy currentsensorlow costuncertaintyTechnikIngenieurwissenschaftenJournal Article10.15480/882.372610.3390/I3S2021Dresden-1016010.15480/882.3726Journal Article
