    • In known high-temperature sensors, the operating temperature in the functional layer of the sensor cannot be accurately adjusted or measured nor exactly regulated. The novel device aims at enabling exact adjustment of the operating temperature on the entire surface of the functional layer. In order to exactly regulate the operating temperature on the entire functional layer, the heating conductor path that is disposed beneath the functional layer is structured in such a way that it comprises different partial heat resistors in the different regions by varying the length of the paths and/or the width of the heating conductor path vary from one partial section to another. Said devices are especially high-temperature gas sensors that are used in the exhaust gas of an internal combustion engine.

    • The gas sensor employs a reference gas channel which enables simultaneous or sequential pumping of oxygen and sensing of the exhaust gas (e.g., to determine if the exhaust gas is rich or lean). The method comprises: using a gas sensor comprising a first electrode and a reference electrode with an electrolyte disposed therebetween, wherein the first electrode and reference electrode are in ionic communication, and a reference gas channel in fluid communication with the reference electrode and an exterior of the sensor; introducing an exhaust gas to the first electrode; applying a voltage to the reference electrode; ionizing oxygen at the first electrode; transferring the ionized oxygen across the electrolyte to the reference electrode; forming molecular oxygen at the reference electrode; ionizing the molecular oxygen on the reference electrode; transferring the ionized oxygen across the electrolyte to the first electrode to create a voltage; and measuring the voltage.

    • The invention relates to a process and circuit for controlling a measuring probe to determine the oxygen concentration in a gas mixture, especially in internal combustion engine exhaust gases, in which a detector voltage corresponding to the oxygen concentration and supplied by a reference probe is converted by a circuit into a pump voltage for a measuring probe. The shape of the detector voltage (UD) is used directly to determine the shape of the pump voltage (UP). A first input (38) of the circuit (36) is connected to a first input (46) of an adder (48) at the second input (50) of which there is an addition voltage and the output (54) of which is connected to the second input (40) of the circuit (36) via an amplifier (58).
