| description | To measure electrode temperature while suppressing a mechanical load applied to a solid electrolyte and to enable stable concentration measurement, in a gas sensor holding a thin pipe-shaped solid electrolyte in a cantilever state.SOLUTION: A gas sensor for measuring the concentration of at least one ingredient in measured gas, includes a sensor pipe made of an ion conductive solid electrolyte formed in a thin pipe shape blocked at a tip end, a measuring electrode that is formed on the outer side on the tip end side of the sensor pipe and contacted with the measured gas, a reference electrode that is formed inside the sensor pipe, and is contacted with reference gas, a heater for heating the sensor pipe, and a temperature sensor for measuring temperature near the measuring electrode. The temperature sensor is provided on the heater, not on the sensor pipe.SELECTED DRAWING: Figure 4
【課題】 細管形状の固体電解質を片持ち状態で保持してなるガスセンサであっても、固体電解質に加わる機械的負荷を抑えた状態で電極温度が測定でき、安定して濃度測定を可能とする。【解決手段】 被測定ガス中の少なくとも１つの成分濃度を測定するためのガスセンサであって、先端が閉塞した細管状に形成されたイオン電導性の固体電解質からなるセンサ管と、前記センサ管の先端側の外側に形成され、被測定ガスに接する測定電極と、前記センサ管の内側に形成され、基準ガスに接する基準電極と、前記センサ管を加熱するヒータと、前記測定電極近傍の温度を測定する温度センサとを備え、前記温度センサを、前記センサ管ではなく前記ヒータに設けていることを特徴とするガスセンサを提供する。【選択図】 図４ |
