摘要： A high sensitive and high responsive gas detecting sensor for detecting the partial pressure of oxygen gas in the exhaust gases is disclosed. The sensor is provided with a sensing element having an electrical characteristic in response to the partial pressure of oxygen gas, a ceramic base member which supports the sensing element so that the sensing element is exposed to the exhaust gases, and electric current conducting means for supplying an electric current to the sensing element. The sensing element is formed of alloy ceramic material composed of 20 to 60 mol percent of cobalt monoxide, 20 to 60 mol percent of magnesium monoxide and 10 to 50 mol percent of nickel monoxide. In the preferred embodiment, the base member is formed into a plate shape and the sensing element is formed on the base member like a film.

摘要： A gas detecting sensor for precisely detecting the partial pressure of oxygen gas in the exhaust gases without being affected by the change of the temperature of the environment thereof, is disclosed. The sensor is provided with a ceramic base member, a film-shaped gas sensing element having a characteristic in response to the partial pressure of oxygen gas which is held by the base member so as to be exposed to the exhaust gases, a film shaped temperature sensing element having temperature coefficient of resistance substantially equal to that of the gas sensing element, which is held by the base member so as to be isolated from the exhaust gases, and an electric current wherein the gas and the temperature sensing elements are connected to each other in series to form an electric junction therebetween, from which output voltage is taken. In the preferred embodiment, the temperature sensing element is embedded within the base member and a heating member is further provided for maintaining both elements within a temperature range in which temperature coefficient of resistance of both elements are substantially equal to each other.
