Electrodes for moisture meter
摘要:
An improved electrode assembly for an electrostatic type moisture meter for powdery or granular material includes an insulator, a high-tension electrode in the form of a stick mounted on the insulator so as to vertically extend therefrom, and a plurality of earth electrodes in the form of sticks arranged around and in parallel with the high-tension electrodes. The high-tension electrode has a protection insulator at the tip thereof. The insulator has air-emitting openings for emitting air therefrom to the base portion of the electrodes to remove the material remaining at the base portion of the electrodes after a measurement. The insulator preferably has an outer face sloped at its periphery.
