Abstract (en)
[origin: WO2016078817A1] The invention relates to a sensor (100) for analyzing an exhaust gas of an internal combustion engine (500). For this purpose, the sensor (100) comprises a cover element (102), which has, in a filter region (106), a plurality of pores (108) for filtering particles out of the exhaust gas, a measuring electrode (110) arranged on the cover element (102) for determining a particle concentration in the exhaust gas, a heating element (112) arranged on the cover element (102) for heating the filter region (106) and/or the measuring electrode (110), and a bottom element (104), which has at least one sensor element (118) for determining a gas concentration in the exhaust gas. The sensor element (118) is covered by the cover element (102) in order to prevent an accumulation of the particles on the sensor element (118). The sensor element (118) is fluidically coupled to an outer environment of the sensor (100) by means of the filter region (106).
