发明名称 Linear response humidity meter for granular materials
摘要 <p>Interface humidity (not included moisture) is determined by measurement of the current flowing between two immersed probes. The probes are in series with a moving coil galvanometer whose return spring has a force equal to the square of the displacement, and supplied by a constant voltage, D.C. source. A linear relationship between displacement and humidity is obtained.</p>
