摘要： PURPOSE:To make a sensor simple in structure, inexpensive and durable, by forming such a gas detecting part that is represented by a specific formula with electric conductivity or semiconductivity, and uses a composite oxide in a crystal structure with 2212 faces as a main component. CONSTITUTION:The sensor is provided with a gas detecting part 3 on the upper side of a heating substrate 2 constituted of a ceramic heater panel. A pair of Pt current adding electrodes 4 and Pt voltage detecting electrodes 5 corresponding to the electrodes 4 are set to the detecting part 3. A main component of the detecting part 3 is represented by the formula, wherein X is not smaller than 0 and smaller than 1, and sigma is not smaller than 0 and not larger than 1. In this constitution of the sensor, the change of an electric resistance value of the detecting part 3 is detected. In the constitution of the electrodes, a current runs also in a part of the detecting part 3 where the resistance changes, so that the change of the electric resistance of the detecting part 3 due to nitrogen oxide gas is effectively detected.

摘要： PROBLEM TO BE SOLVED: To establish a diagnosis method for an electrochemical type sensor capable of rationally estimating a factor other than abnormality related to a humid condition between a detection electrode and a counter electrode and abnormality due to jamming of a part of or the whole diffusion limitation hole.SOLUTION: The AC of an interface abnormality diagnosis frequency is applied between a detection electrode and a counter electrode, and the capacity component of impedance between the detection electrode and the counter electrode is detected. When the capacity component of the detected impedance increases more than the capacity component of reference impedance in a normal state, it is diagnosed that an electrode catalyst forming the detection electrode or the counter electrode is possibly in an abnormal state due to the influence of the electrolyte of an electrolyte layer.
