Abstract

PURPOSE: To make stable the operation as sensor element and to simplify the constitution, by supplying the reference electrode oxygen partial pressure control current in response to the change in the voltage applied to heater for temperature maintenance.
CONSTITUTION: Oxygen ion conductive solidstate electrolyte 4 is used, oxygen ions are moved in the electrolyte 4 with the control current supplied through the connection to external power supply Vc, and oxygen partial pressure of the reference electrode 3 is controlled. Further, when an external power supply VB is input, the heater 2 is heated, and the voltage of the power supply VB is changed depending on the running state of an automobile, the oxygen sensor element temperature is changed and the sensor element request current is also changed. Thus, the control current Ic controls the reference electrode oxygen partial pressure, and the electromotive force E corresponding to the difference between the partial pressure of oxygen of the reference electrode 3 and that of the measuring electrode 5 is detected at the measuring device Vs.
