Abstract (en)
[origin: WO2009127469A1] The invention relates to a sensor element (112) for determining at least one physical property of a gas in a measuring gas chamber (130), in particular for determining an oxygen concentration in the exhaust gas of an internal combustion engine. The sensor element (112) has at least two electrodes (124, 128), and at least one solid electrolyte (126) connecting the electrodes (124, 128). Furthermore, the sensor element (112) has at least one heating element (136) having at least two heating contacts (144, 146), wherein at least one first heating contact (144) of said heating contacts (144, 146) and one first electrode (124) of said electrodes (124, 128) can be contacted via a shared connection line (152), and wherein at least one second heating contact (146) of said heating contacts (144, 146) and one second electrode (128) of said electrodes (124, 128) are connected using a shared ground line (148).
