    摘要: The invention is based on a planar sensor element for determining the oxygen content of gas mixtures, particularly in internal combustion engines such as those found in automobiles. The sensor element comprises a measuring cell and an integrated heat conductor embedded in electric insulation all of which rest on a solid electrolyte substrate. At least one hollow chamber separates one or several parts of the insulation from the solid electrolyte substrate in order to effect an improved decoupling of the sensor's heat conductor from its measuring cell.
