FIELD: measuring equipment.
SUBSTANCE: chamber comprises the body, the inner side of which faced with the optical meshed screen, and is made of the porous sound absorbing material. The body has the tube from the side of the input gas main. This tube is equipped with the forced-draught variable fan with the adjustable angles setting. This fan is set in communication with the clearance between the body and the chamber. The optical scanning system of the acoustic and gasdynamic parameters recording is placed within the chamber at the output of the gas main with the nozzle and is equipped with the combined sensor of the total, static pressure and the temperature. There is the outlet nozzle on the body opposite side. It is set in communication with the clearance between the chamber and the body. Within the tube, there is the fan with the adjustable angles setting, before the inlet of which the optical gasdynamic parameters control system, the adjustable damper with the feedback transmitter and with the actuating unit are installed.
EFFECT: reliability and integrity growth.
