Measurement of Complex Permittivity of Dielectrics and Its Applications

Abstract

Measurement of dielectric properties provide valuable information about the physical parameters of agricultural & food products. Precise measurement of complex permittivity (CP) gives details of moisture content in products. In the present work we have used simple electronic method for the measurement of CP. We have used microcontroller for measurement & calibration of CP. The electronic circuit is designed with the help of low cost locally available components. The software program is developed in C language in Keil environment. The results obtained for CP are accurate and can be used for the estimation of moisture content. The electronic circuit can be used for the measurement of other dielectric properties such as dielectric strength & loss. The combine effect of all the dielectric properties can be easily implemented in the software.
