Abstract
A sensor assembly includes a sensor housing or mounting apparatus for positioning in a free flowing stream of particulate matter in order to accomplish on-line measurement of a physical property of the material such as moisture content. The housing has an inlet nozzle, a mid-section or sensing chamber, and a discharge section. The inlet nozzle has flow deflector plates that intercept a sample of material from the process stream from a single plane and channel it to the sensing chamber. A sensor is embedded in the walls of the sensing chamber and positioned to sense the material property of the passing sample. A discharge nozzle extends from the sensing chamber and has a constricted discharge opening in order to regulate flow through the sensing chamber. The discharge nozzle has a pair of downwardly convergent deflector plates such that the flow of particulate matter is restricted in a single vertical plane that is perpendicular to the vertical plane referenced by the inlet section.
