Patent DE-3834987-A1 (DE)
Inventor: DIETZ HERMANN DR
IPC: G01N27/416
Filed: 1988-10-14
Abstract: A sensor element for limit current sensors used to determine the lambda  value of gas mixtures, in particular exhaust gases of internal combustion engines, has outer and inner pump electrodes arranged on a O<2-> ion conductive solid electrolyte. The inner pump electrode is exposed to the measurement gas supplied through a diffusion slot and the diffusion slot is covered by the solid electrolyte.
