Abstract: 티타네이트로 이루어진 센서 소자를 배기 가스 중에 함유된 염소, 인 및 황 화합물로부터 보호하기 위해, 산소 감지 센서 영역을 다공성 SrTiO 3 층으로 커버한다.  적합한 λ프로브는 그것의 긴 수명에도 불구하고 지금까지 사용되지 못했는데, 그 이유는 그것의 출력 신호가 보호층의 오염으로 인해 너무 큰 드리프트를 나타내기 때문이다. 
     다공성 Al 2 O 3 커버층(34)은 2개의 Pt-전극(2, 2')에 의해 결합되는, Al 2 O 3 기판(1)상에 증착된 가스 센서 SrTiO 3 층(3)을 커버한다.  전기 절연 Al 2 O 3 층(34)은 바람직하게는 SrTiO 3 로 이루어지며 배기 가스에 노출된 보호층(4)을 지지한다.  이러한 구성은 산소 부분 압력을 나타내는 센서 출력 신호가 오염되지 않은 SrTiO 2 -센서층(3)의 저항 또는 전도도에만 의존하는 것을 보장한다. 
     본 발명은 특히 신속한 산소 센서, λ프로브, 공기 비율의 실린더 선택적 조절, 및 침식성 성분을 함유하는 가스 혼합물에 노출된 가스 센서에 적용된다.
