Abstract
The invention relates to a solid oxygen sensor consisting of an electrolytical cell, with a first electrode exposed to the atmosphere whose partial oxygen pressure is to be measured, a second electrode exposed to a reference atmosphere and a solid electrolyte in surface contact with both electrodes, the material of the electrolyte being a ceramic oxide or a vitreous phase with pure ion conduction and at least the first electrode containing a non-stoechiometric ceramic oxide. According to the invention, the first electrode consists of a mixture (CERMET) of at least one non-stoechiometric ceramic oxide and a metal, the latter being chosen from the group constituted by gold, platinum, nickel and chromium. Such a sensor can record the partial oxygen pressure in a wide measuring range and is rather insensitive against poisoning of the electrodes by carbon monoxide or lead.
