摘要
An oxygen sensor has a solid electrolyte layer placing a reference electrode and a measurement electrode. A control circuit producing AC current through the electrolyte between the electrodes to establish a reference oxygen partial pressure at the reference electrode- electrolyte interface includes a comparator for reference voltage and output between the electrodes, a multiplier for the output voltage, and a control current regulator utilizing comparator and multiplier outputs so that current intensity depends on output voltage value when one voltage is higher than the other to compensate variations duing to temperature.
