Abstract (en)

[origin: EP2639512A2] The appliance (101) has a lambda probe (102) that is connected with a down converter (109), or the lambda probe comprises the down converter. A sensor system (107) is arranged upstream of components of the lambda probe, where the sensor system comprises the down converter. An output voltage of the down converter is set as a probe voltage (U out) that is applied to a probe heater (104) of the down converter. A switch of the down converter is arranged with a frequency lying in a range between 20 KHz and 150 KHz. An independent claim is also included for a method for operating a lambda probe.
