DEVICE TESTING DUST LOADING OF AIR

摘要

FIELD: labor protection, instruments measuring air dust content. SUBSTANCE: blast engine is connected to rotameter by means of inlet branch pipe. Two-way gate valve with filter attached to its one side is positioned between inlet branch pipe and rotameter. The latter communicates with chamber. Sensitive element of pickup of dielectric permittivity of environment whose electric output is linked to proper input of microprocessor test unit is placed inside chamber. EFFECT: increased timeliness of test of dust loading of air. 1 dwg
