摘要： PROBLEM TO BE SOLVED: To provide a mixed potential type sensor for detecting various gases in a gas mixture enabling its operation in a wide temperature range and greatly facilitating temperature control by optimally matching the sensor to ambient conditions. SOLUTION: The sensor includes an exhaust gas electrode and a second electrode with a mixed potential characteristic or Nernst characteristic disposed in an exhaust gas chamber or a reference electrode disposed in an air reference duct. These electrodes contain different electrode materials and exhibit different sensitivities for the types of gases. One and the other electrodes function as a sensor electrode and a reference electrode, respectively. A measurement unit measuring a potential generated between the exhaust gas electrode and the reference electrode is provided, A load resistance with a variable electric resistance connected between the first electrode and the reference electrode or second measurement electrode is connected to make the sensor operate over a wide temperature range.

摘要： Disclosed is a NOx sensor (10) for measuring a NOx concentration comprising a main pumping cell (28) and a detecting electrode (40), the main pumping cell (28) including an electrode (an inner pumping electrode (24) and an outer pumping electrode (26)) having no decomposing/reducing ability for NOx or a low decomposing/reducing ability for NOx, to be used so that an oxygen concentration in a measurement gas is controlled to have a predetermined value at which NO is not substantially decomposable, and the detecting electrode (40) having a certain decomposing/reducing ability for NOx or a high decomposing/reducing ability for NOx, to be used so that NOx is decomposed to measure the NOx concentration by measuring an amount of oxygen produced during this process, wherein a cermet electrode composed of a Pt-Rh alloy and a ceramic component is used as the detecting electrode (40). Accordingly, it is possible to suppress the oxidation of Rh and the reconversion into the metal contained in the detecting electrode (40), stabilize the impedance, and stabilize the sensitivity to NOx.
