ABSTRACT:
A sensor for measuring partial pressures of oxygen with an ion-conducting lid electrolyte of zirconium dioxide as the sensor element, which is arranged between two electrodes for measuring an electrically measurable quantity, is improved so that it is usable at an operating temperature of about 200.degree. C., by providing that the zirconium dioxide as the solid electrolyte is solely in its tetragonal modification and containing an addition of about 2-3 mol % yttrium oxide.
