GAS ANALYZER Russian patent published in 2018 - IPC G01N33/00 

FIELD: measurement; testing.

SUBSTANCE: group of inventions refers to the detection and monitoring of gases and vapors in the ambient air. Presented sensor unit for gas detection is provided with a pressure-tight measuring channel, a gas inlet for introducing gas into the measuring channel, gas outlet for the discharge of gas from the measuring channel and the pump unit for evacuating the measuring channel, wherein the measurement channel includes a gas sensor for detecting gas and a heating unit for heating the gas sensor, wherein the sensor unit is designed to be operated in a measuring mode and a regeneration mode, wherein, in the regeneration mode the measuring channel is evacuated and the gas sensor is heated. Gas analyzer comprising the above sensor unit and a method of operating the sensor unit are also described.

EFFECT: possibility of an early and reliable gas warning is achieved due to a shorter sensor operating time.
