Abstract
A continuous flow moisture tester includes first and second electrodes defining a capacitive-type test cell. The first electrode comprises a generally cylindrical tube of electrically conductive material, and the second electrode comprises a generally planar body of electrically conductive material disposed adjacent an inner wall of said first electrode member to define a substantially unobstructed passageway between the electrode members. Material carrying members are connected at an inlet and outlet of the passageway for providing a substantially constant flow of material therethrough and for maintaining the passageway substantially evenly filled with flowing material. An electrical circuit is connected with the test cell for producing a signal corresponding to the moisture content of the material flowing therethrough. The circuit is arranged for producing the above-described signal substantially independent of the density of the material or any variations therein, and in accordance with the electrical properties of the material-filled capacitive test cell.
