Abstract
An agricultural permittivity sensor has a drive electrode and a separate sense electrode. Both electrodes have surfaces that face the sensed material and the surfaces are co-planar. The drive electrode receives an excitation signal and generates an electric field that produces a current in the sense electrode. The current is indicative of a test weight of the sensed material.
