Abstract

The transducers employed to measure the concentration of CO₂ launched to the atmosphere are only calibrated in a static manner. Thus, the transient effects of the flow of such gas are not properly recorded. This study aims at presenting a new methodology to characterize the dynamic performance of carbon dioxide transducers, and to experimentally determine its transference function. To achieve this goal, a device was developed in which the variables influencing the measures are controlled, allowing the transducer’s dynamic response to be assessed.
