摘要： The invention concerns a device comprising a sensor for supplying a voltage representing the relationship between an oxygen pressure reference and the oxygen pressure in a volume of the sensor and provided with electrodes (12, 14) for passing a pumping current controlling said oxygen pressure in the volume and controlling/commanding means with a digital controller (26) receiving said representative voltage on an input and for supplying the pumping current. Said controlling/commanding means supply the pumping current in the form of a continuous, gradual and non-chopped current controlled by the digital controller so as to automatically set the input voltage at a predetermined value.
