The utility model relates to gas
infrared gas analyzer technical field, and disclose a kind of high-precision
gas analyzer.The high-precision
gas analyzer includes:
flue pipe, the inside fixed mounting of
flue pipe has fixed plate, the top fixed mounting of
flue pipe has top cover, the outside fixed mounting of flue pipe has support ring, the top fixed mounting of support ring has PLC controller, the left side of flue pipe is inserted and installed with
infrared gas analyzer, the left side of flue pipe is inserted and installed with
barometer,
barometer is located the top of
fan blade, the air pressure size below the fixed plate in flue pipe can be monitored in real time, and
monitoring data is transmitted to PLC controller, set air
pressure threshold interval by PLC controller, by PLC controller to compare actual data with set threshold value, and according to comparison data to adjust the rotational speed of driving motor and the rotation angle of movable plate, to adjust internal
flue gas air pressure, so that air pressure is kept at proper size, to facilitate
infrared gas analyzer to analyze
flue gas.
