Measurement of the dielectric properties of wheat using the Q-Meter


, : Measurement of the dielectric properties of wheat using the Q-Meter. Engenharia Agricola 18(2): 92-106

The aim of this work was to develop a method to determine the relative permittivity ( epsilon '), and the dielectric loss factor ( epsilon "), of wheat seeds by measuring the quality factor (Q) using an electric circuit. These dielectric properties allow the indirect estimation of the moisture content of agricultural products such as grain and seeds. Measurements were made using a Q-Meter, operating in the frequency range 100 kHz to 10 MHz.
