Abstract
A compact and durable gas detecting sensor for detecting the partial pressure of oxygen gas in the exhaust gases of an internal combustion engine is disclosed. The sensor is provided with a sensing element made of ceramic material having an electrical characteristic which varies in response to variations in the partial pressure of oxygen gas, such as CoO, a base member made of electrically insulating ceramic material, such as alumina, and electrodes held by the base member. The sensing element is integrally fixed to the base member through an intermediate layer made of ceramic material which is non-reactive with the sensing element.
