Abstract
A light transmission powder and granular material measuring apparatus for a continuous production line assembly is provided. A conduit line is capable of being connected to the production line to provide an alternative flow path for the powder and/or granular material. A light transmission cell is mounted in the conduit and a measurement apparatus is provided for measuring the light as it passes through the light transmission cell. A valve member can interconnect the conduit to the production line to control the flow of powder and/or granular material, whereby a measurement can be made when the valve is activated to permit the flow of powder and/or granular material to provide an accurate measurement, and also a measurement can be made as a reference measurement during a calibration cycle when the valve is activated to stop the flow of powder and/or granular material. The light transmission powder and/or granular material measuring apparatus can be provided as a modular unit for mounting in a continuous production line and can be automatically controlled to periodically calibrate its measurements.
