Sensor element for detection of sooty particles emitted from vehicle, has supply lines comprising measuring electrode supply line insulation, which surrounds supply lines and is arranged over and/or adjacent and below supply lines

摘要

The sensor element has measuring electrodes (3, 4), measuring electrode supply lines (5, 6) and measuring electrode contacts (7, 8) arranged on an insulating layer (9). The insulating layer is arranged on a carrier layer (10). The supply lines have measuring electrode supply line insulation, which surrounds the supply lines. The supply line insulation is arranged over and/or adjacent and below the supply lines. A testing electrode is arranged between the supply lines. A testing layer and/or the carrier layer is made of yttrium doped zirconium oxide. An independent claim is also included for a method for determining and compensating shunt resistance of a sensor element.
