“…Grain moisture meters were subsequently developed based on this principle. Later, the use of capacitance measurements for moisture determination in grain was studied, and moisture meters were developed that utilized relationships between instrument readings and reference method moisture determinations [3][4]. The historical development of electrical grain moisture meters has been reviewed previously [2,[5][6].…”

Abstract-The importance of moisture measurement in grain and seed is discussed, and a brief history of the development of moisture sensing instruments, based on sensing electrical properties of these materials, is presented. Data are presented graphically on the permittivities or dielectric properties of grain and seed showing their variation with frequency, moisture content, temperature, and bulk density, and references are cited for further information. More recent developments on microwave measurements for moisture content and bulk density sensing are briefly described, and numerous studies are cited providing sources of information on these techniques.

“…Literature review: Part I Capacitance was used for determining water concentration in plant tissues as early as 1929 when Burton and Pitt (1929) measured moisture in wheat kernels. Tliey described an r-f (radio frequency) oscillator, with the customary I-C (inductance and capacitance) tank in the plate eircuit of a vacuum tube triode and a tickler coil to couple inductively the tank electrical field to the tube control grid to sustain oscillation.…”
