A GAS SENSOR CHAMBER AND ODOUR DETECTION METHOD

摘要

The invention relates to a chamber ( 2 ) for gas sensors ( 9 ) to be used in a device ( 1 ) for detecting aromas or odors. The chamber ( 2 ) comprises three portions ( 5, 6, 7 ) in which there is a uniform, turbulence-free flow (F) of gas or vapors to be analyzed, and at least one gas sensor ( 9 ) positioned in the central portion in such a way as to be immersed in and to laterally and tangentially interact with the flow (F). The chamber ( 2 ) also comprises a heating and temperature regulating device ( 16, 17 ). The invention also relates to an odor detection method which comprises a step in which a uniform, turbulence-free flow (F) of gas or vapor interacts with a gas sensor ( 9 ) laterally and tangentially.
