    • PURPOSE:To remove a detection error by combustible gas, by allowing sensitivity to combustible gas and that to oxygen well-balanced. CONSTITUTION:A beater built-in ceramic pipe 4 is attached to the leading end of a 6- hole tube base body 2 made of a alumina. The pipe 4 has a membrane heater 6 provided therein to heat a gas detection piece 8 and a temp. detection piece 10 to definite temp. Detection pieces 8, 9 are provided to the substrate 2 and the recessed part of the pipe 4 through threshold parts 12. The detection piece 8 is constituted by embedding a pair of noble metal electrodes 16, 18 in a porous ceramic piece made of a compound A SnO3-delta and coating said ceramic piece with a mullite film 20.
    • 目的:通过可燃气体消除检测误差,允许对可燃气体的敏感性以及对氧气平衡的敏感性。 构成:将搅拌器内置的陶瓷管4安装在由氧化铝制成的6孔管基体2的前端。 管4具有设置在其中的膜加热器6,用于加热气体检测片8和温度。 检测片10到确定温度 检测片8,9通过阈值部件12提供给基板2和管4的凹部。检测片8通过将一对贵金属电极16,18嵌入由化合物制成的多孔陶瓷片中 SnO3-δ并用莫来石膜20涂覆所述陶瓷片。

    • PURPOSE:To improve durability and sensitivity and to decrease a detection error by constituting a gas detecting piece and temp. detecting piece of a specific compd. CONSTITUTION:The gas detecting piece 8 and temp. detecting piece 10 are provided via a threshold part 12 in the recess between a base body 2 and a ceramic pipe 4. The piece 8 is constituted by embedding a pair of electrodes into the porous ceramic piece of the compd. ASnO3-delta having >=15% open porosity (A is one member of the group consisting of Ra, Ba, Sr and Ca, delta denotes a non-stoichiometric parameter). The piece 10 is constituted by embedding a pair of electrodes to the dense ceramic piece of the compd. ASnO3-delta having
