摘要： The invention relates to a circuit assembly for operating a sensor array, in particular, a gas sensor array for detecting gases, which comprises at least one signal line. According to said invention, a signal line is divided into two parallel line branches with a sensor and a diode, preferably a Schottky diode, arranged in each of said two parallel line branches, whereby the two diodes have opposite electrical polarity. The use of different polarity diodes permits actuation of both sensors through only one signal line. It can be determined if the current flows through one or the other of both sensors by merely polarizing the electrical potential applied to the signal line appropriately.

摘要： The invention is directed to a circuit arrangement for operating an exhaust-gas probe including a NOx double chamber sensor. The exhaust-gas probe includes: a heatable solid-state electrolyte body having first and second pump chambers and diffusion barriers for separating the chambers from each other and from the exhaust gas. A third chamber communicates with the atmosphere. An external pump electrode is exposed to the exhaust gas and a first oxygen pump electrode is disposed in the first pump chamber. A second oxygen pump electrode is disposed in at least one of the first and second pump chambers and a nitrogen oxide pump electrode is disposed in the second pump chamber. An air reference electrode is disposed in the third chamber. Only one pump voltage generating circuit unit is provided and a switching device switches the pump voltage generating circuit unit between respective ones of the pump electrodes. The pump voltage generating unit functions to generate, in a controlled manner, all of the voltages applied to the pump electrodes in dependence upon respective reference voltages.

摘要： A method and a sensor element are provided for determining the concentration of an oxidizable gas in a gas mixture, e.g., in exhaust gases of internal combustion engines. Within the sensor element of a gas sensor, nitrogen oxides, hydrogen, and/or carbon monoxide contained in the gas mixture are at least partially removed in an initial step. In a further step, the concentration of the gas to be detected in the gas mixture freed of nitrogen oxides, carbon monoxide and/or hydrogen is ascertained.

摘要： A gas sensor based on solid electrolyte is proposed for measuring a gas component in a gas mixture, having at least one sensitive region, which has a first means for producing a reaction gas from an additional gas component of the gas mixture. A second means is situated in the sensitive region of the gas sensor, using which the residual content of the reaction gas may be determined, after a reaction that takes place between the reaction gas and the gas component to be measured.

摘要： A device for operating a gas sensor having both at least one pump cell and a measuring cell is provided. A constant current source is provided that makes available a pump current which acts upon an outer electrode of the pump cell. The constant current source provides at least two different amounts of the pump current and/or allows for an alternating operation having ON phases and OFF phases, the duration of the ON phases/OFF phases being specifiable. The device may be largely implemented in digital circuitry and adapted to different requirements.
