A sensor device for sensing at least a proportion of at least one gas component of a gas in a measurement gas space, in particular for detecting oxygen in an exhaust gas of a combustion machine, is proposed. The sensor device includes at least one sensor element. The sensor element includes at least one first electrode and at least one first reference electrode and at least one second reference electrode. The second reference electrode is connected to at least one reference gas channel. The first electrode is connected to the first reference electrode and the second reference electrode by at least one respective solid electrolyte. The sensor element has at least one diffusion element between the first reference electrode and the reference gas channel.

Step-change sensor for pumped and unpumped operation

A sensor element for determining a gas component or particles in a measuring gas, having a first and a second measuring electrode, the measuring electrodes being developed as interdigital electrodes having a row of intermeshing branches as well as a main conductor each, to which the branches are connected in an electrically conducting manner; and the branches of the interdigital electrodes being aligned essentially in parallel to a longitudinal axis of the sensor element.
