摘要： A device for measuring the pressure of a gas mixture composed of gas components has an amperometric sensor that works on the limiting current principle, having two electrodes connected to a direct voltage that are situated on a solid electrolyte, of which one electrode is covered by a diffusion barrier, and a measuring element for measuring the limiting current flowing via electrodes as a measure for the gas pressure. For the purpose of error-free measurement of the gas pressure in a gas mixture in which the concentration of the gas components fluctuates with time, means are provided which fix the mole fraction of a gas component, drawn upon for pressure measurement, that is present upstream of the diffusion barrier at a constant 100%, at least during the pressure measuring phase. In one preferred exemplary embodiment, these means include a storage volume that is adjacent to the diffusion barrier which is separated from the gas mixture by a diffusion path, and two electrodes, situated on the solid electrolyte, for pumping of the gas component into the storage volume.

摘要： The invention concerns a procedure to determine a mass of particles or a particle mass flow in an exhaust gas system of an internal combustion engine, whereby at least one resistive particle sensor is disposed in the exhaust gas system of the internal combustion engine. The measured signal change of the particle sensor is compared with a predicted signal change of the particle sensor ascertained from an engine model.If the measured signal change of the particle sensor and/or the predicted signal change of the particle sensor are corrected while taking into account the influencing variables on the transverse sensitivities of the particle sensor, it is possible when ascertaining the predicted signal change of the particle sensor that a compensation for the transverse sensibilities can result even during dynamic operating point changes of the internal combustion engine, which occur faster than the actuation of the particle sensor. This is the case because the correction can even be implemented for small predicted signal changes, such as those occurring during a currently transpiring operating point of the internal combustion engine. Because the predicted signal changes are ascertained from a set of characteristic curves of the engine model, these measurement intervals capable of being assigned to very short times and for that reason to individual operating points of the internal combustion engine can be determined with the very small predicted signal changes, which are required for this purpose.
