Wang Ping Wang · Applied Mechanics and Materials · 2014
Moisture measurement of grain is an important aspect of its quality indicators. In this paper, a resistive grain moisture meter device was developed and the measuring principle and adopted scheme were illustrated. The structures and work principles of the resistance-to-frequency switching circuit and the temperature compensation circuit were introduced in detail. Finally, this paper gives a brief introduction to the mechanical grain sample. The resistive grain moisture meter has the advantages of fast testing speed, high precision and low cost, it’s one of the important tools in measuring grain moisture.
