| 摘要 |
<p>The invention concerns a sensor for determining the concentration of oxidisable elements in a gas compound, in particular for determining one or more of the gases, NOx, CO, H2 and especially unsaturated hydrocarbons, by measuring the tension between a measuring electrode (1, 2) and a reference electrode (3) or by measuring the tension between two measuring electrodes [(1) and (2)]. Selectivity of response for individual components of the measured gases can be improved by using specific material for the measuring electrodes, in particular semiconductors. By using porous fixed electrolytes, a reference gas atmosphere can be avoided and, therefore, increased miniaturisation and constructive simplification can be achieved.</p> |
