Abstract : A fluidic partial pressure sensor for measuring the partial pressure of a gas constituent in a mixture relative to a reference gas. The pressure drop output of a fluidic bridge concentration sensor is connected to the aspirated input of a fluidic aspirator which is operated in its sonic or saturated region. By virtue thereof, the vacuum created in the aspirated input is directly proportional to the ambient pressure at the output of the aspirator. Since the ratio of the bridge pressure drop is therefore made constant, the output pressure of the bridge sensor is thereby directly proportional to the partial pressure of the gas constituent of interest.
