Sensor head for a dry powder agent

摘要

A sensor head (24A) for a dry powder agent according to an exemplary aspect of the present disclosure includes a housing (50) defined along an axis (S) along which light is communicated, the housing (50) defines a multiple of apertures (52) transverse to the axis (S) and in communication with a measurement volume (72) along the axis (S). Each of the multiple of apertures (52) defines a longitudinal length along the axis (S) which is less than a lateral length defined around the axis (S). A mirror (62) is within the housing to reflect the light through the measurement volume (72).
