Abstract

본 발명은 고온 고습한 곳에서 도시가스의 누설을 감지할 수 있는 센서에 관한 것으로, 알루미늄졸과 알루미나, 증류수를 혼합한 페이스트를 백금선에 부착, 소성하여서된 소결체를 얻어 이를 촉매 수용액에 침적, 건조후 건조공기와 수증기 공급하에서 소성하고 촉매 수용액에 침적 건조후 다시 건조 공기 공급하에서 소성함을 특징으로 하는 도시가스용 가스센서의 제조방법에 관한 기술임.The present invention relates to a sensor that can detect the leakage of city gas at a high temperature and high humidity, and attaches a paste mixed with aluminum sol, alumina and distilled water to a platinum wire to obtain a sintered body obtained by sintering and drying it in an aqueous solution of catalyst. After the firing under dry air and water vapor supply, immersed in a catalyst aqueous solution, dried and fired again under dry air supply technology.
