Sensitivity characteristic slope 2. Basic Measuring Circuit & Stability 1/5 NOx 센서는 고도로 성장하는 생활환경에서 대단히 많은 종류의 위험한 가스가 존재하는 가스중의 하나이다. 인간의 감각기관으로는 위 험 가스의 농도를 정량 하거나 종류를 거의 판별할 수 없다. 이에 대응하 기 위해 물질의 물리 ` 화학적 성질을 이용한 가스센서가 개발되어 가스 의 누설 감지, 농도 측정, 기록, 경보 등에 사용되고 있다. 매우 고가인 고체전해질 타입인 NOx 센서에 반하여, 반도체식 가스센서를 이용하여 보다 용이하게 사용할 수 있게 하고자 개발된 센서 이다. 특히 수입센서의 대부분 의존해온 국내 자동차용 AQS 센서에 맞게 개발된 제품으로 차량의 배기가스에서 주로 발생하는 NOx 가스를 감지토록 개발된 센서이다.
