Abstract
A measurement system for a dry powder agent includes a sensor system which includes at least one sensor head at least partially within a powder calibration column and a control system in communication with the sensor system.
Claims16
A calibration system for a dry powder agent sensor head comprising:
- a powderizer calibration column including an observation tube, a test section in fluid communication with said observation tube, and a powder capture box in fluid communication with said observation tube wherein said powder capture box defines a relatively large volume compared to said observation tube to prevent recirculation of a dry powder agent back into said test section;
- a sensor system which includes at least one sensor head at least partially within said powderizer calibration column;
- and
- a control system in communication with said sensor system.

A powderizer calibration column comprising:
- an observation tube;
- a test section in fluid communication with said observation tube;
- a powder capture box in fluid communication with said observation tube, wherein said powder capture box defines a relatively large volume compared to said observation tube to prevent recirculation of a dry powder agent back into said test section;
- a powder feeder system operable to communicate a dry powder agent into said observation tube opposite said powder capture box at a defined rate;
- and
- an inert gas distribution system operable to communicate an inert gas into said observation tube opposite said powder capture box at a define rate.
