Method and apparatus for measuring parameters of material

摘要: A method and apparatus for measuring at least one parameter of material are disclosed herein. The includes generating multiple frequency signals having frequencies selectable by control signals, combining the into a combined signal components, applying as an excitation to sensing element. response is determined each using output from element, analysis performed determine parameters material. element may include capaciflector sensor located non-intrusively along surface conveyor. However, other elements such capacitive, resistive inductive be used. being measured mass flow rate moisture content. circuit which applies conditioning determines based upon processing performing analysis. used measure moved vehicle-mounted pink or white noise generator circuit.
