  • Gas sensor chip and gas sensor provided therewith
    Patent number: 8156789
    Abstract: To provide a gas sensor chip, and a gas sensor provided therewith, capable of producing stable output characteristics over an extended period of time even when installed in a harsh environment such as a boiler smokestack carrying exhaust gasses. There is a backside structure wherein a catalyst carrier that contacts a gas to be measured is disposed on one side of a thermal conductor, a temperature sensing portion is disposed in a location that does not contact the gas to be measured, on the other side of the thermal conductor, and the temperature sensing portion measures the temperature corresponding to the temperature of the catalyst carrier through the thermal conductor, to enable the sensing of the amount of flow over an extended period of time without the temperature sensing portion being negatively affected by the gas to be measured.
