Abstract
In this paper an eddy current sensor with new and simple contactless structure to determine the concentration of electrolyte solution is presented. The sensor determines the concentration of solution by detecting the change in inductance of the sensing coil due to the formation of eddy current inside the conducting solution. The responses of the sensor for various concentration solution of NaCl and K 2SO4 show distinct change in inductance for various concentration as well as for different types of solution
