ABSTRACT:
An electrochemical gas sensor is self-diagnosed on the basis of an output waveform that is generated when a power source of said gas sensor is turned on after said power source has been turned off for a short time and an output waveform that is generated when said power source is turned on after said power source has been turned off for a long time. In a normal gas sensor, when the power source is turned on after the power source has been turned off for the short time, a bottom will be generated in the potential of the sensing electrode side, and when the power source is turned on after the power source has been turned off for the long time, a peak will be generated in the potential of the sensing electrode side.A self-diagnosis of the electrochemical gas sensor can be done without pulse power source for self-diagnosis, and the dead time from self-diagnosis until start of detection can be shortened.
