A method and apparatus for monitoring during dynamic processes that determines when effective measurements of thermal effusivity and/or thermal conductivity can be made during a portion of a cycle during a calibration phase then , measures thermal effusivity and/or thermal conductivity during a subsequent dynamic process in dependence upon the time delay value and the measurement duration value until a desired value is obtained. A sensor having a measurement period of between one of two seconds allows monitoring of materials during dynamic processes such as tumbling blending, mixing, and , rocking. For example measurements can be made until a value indicative of a desired mixture …
