Abstract : A fluidic partial pressure sensor for obtaining a direct indication of the partial pressure of a gas constituent in a mixture relative to a reference gas. A fluidic bridge's geometry is so designed and structured that if the pressure across the bridge is maintained constant, the pressure differential between the two channels thereby becomes directly proportional to the partial pressure of the gas constituent of interest. A typical bridge sensor therefore can provide a direct indication of partial pressure. The geometry of the bridge network is chosen so that the sensor gain constant varies linearly with ambient pressure. (Author)
