METER, SYSTEM AND METHOD OF MEASURING MASS CONCENTRATION OF DUST PARTICLES Russian patent published in 2019 - IPC G01N15/06 

FIELD: measurement.

SUBSTANCE: invention relates to instrumentation, particularly, to instruments for measuring dust content of air, namely to devices for measuring concentration of dust particles and systems for measuring mass concentration of dust particles. Disclosed is a system for measuring mass concentration of dust particles, comprising a device for transmitting data, inside which a mass concentration meter of dust particles is located, comprising a meter body, a printed circuit board with a microcontroller, connected to them, at least, two dust sensors and output interface of the meter, characterized by that it additionally comprises a heating element and a fan which are electrically connected to the microcontroller; at least, one input channel connected to dust sensors, at least one outlet channel and at least one inlet flow temperature sensor. System implements a method of measuring mass concentration of dust particles.

EFFECT: technical result is possibility of operation mass concentration meter of dust particles at negative temperatures of incoming atmospheric air with high accuracy and ease of measuring concentration of dust particles with size of up to 10 mcm, as well as ease of manufacture of the claimed meter, high wear resistance and longer service life of the mass concentration meter of dust particles.
