Aimed to the problems of difficult installation and low measurement accuracy in high moisture, the grain moisture sensor has improved from the traditional parallel polar plate probe to plane polar plate probe. The plane polar probe with protect pole was used to decrease the affect of the stray capacitance and interference, and some critical parameters of the plane polar probe that influenced sensitivity and accuracy of the sensor were proposed. The finite element method was used to analyze the electric field and capacitance of the plane polar probe.
