Gas sensor i.e. lambda sensor, element for determining oxygen concentration in exhaust gas of internal combustion engine, has conductor producing heating zone with increased temperature, where outer contour of end section is adapted to zone

摘要

The element has a ceramic sensor body (10) comprising an electrical resistor-heating conductor (14) that is connected to heating voltage over a conductor path (15), where the conductor path runs in the sensor body. The heating conductor produces a limited heating zone with increased temperature in a body end section (101), where an outer contour of the end section is adapted to the heating zone in such a manner that the distance between the outer contour and a circumferential line of the heating line less varies or is constant along a part of the circumferential line.
