FIELD: machine building. ^ SUBSTANCE: calibrating system for sensor head for dry powder reagent consists of powder calibrating column. Also, the system consists of a sensor system including at least one sensor head at least partially installed inside the powder calibrating head. Additionally, the calibrating system consists of a control system connected with the sensor system. The powder calibrating column is equipped with a measuring tube, a measuring section communicating with the measuring tube and a box for accumulation of powder communicating with the measuring tube. The powder calibrating column additionally has a system for supply of powder and a system for distribution of inert gas. The system of powder supply delivers dry powder reagent into the measuring tube from the side opposite to the box of powder accumulation at a specified rate of delivery. The system of inert gas distribution supplies inert gas at a specified rate into the measuring tube from the side opposite to box of powder accumulation. ^ EFFECT: simultaneous measurement of fire extinguishing reagent concentration in aerosol cloud and calibration facilitating measurement of reagent concentration for certification tests of powder system of fire extinguishing at aircraft. ^ 19 cl, 2 tbl, 15 dwg |
