Sensor unit manufacturing method for determining physical characteristic i.e. oxygen concentration, of gas mixture i.e. exhaust gas, involves separating areas of output electrode such that two electrodes are formed from areas, respectively

摘要

The method involves attaching an output electrode (116) on a solid electrolyte (114), where the output electrode has an area (122) and another area (124). The areas of the output electrode are separated from each other using a laser (130) such that an electrode is formed from the area (122) and another electrode is formed from the area (124). The electrodes are electrically separated from each other, where the output electrode includes two inlets (118, 120). An independent claim is also included for a device for executing a method for manufacturing a sensor unit.
