Abstract

A temperature measuring device for an electric appliance such as a fryer includes at least one temperature sensor in the form of an electric resistor, to which at least two different measuring voltages can be applied with cyclic switching between the measuring voltages. The temperature sensor is connected to a control, which includes a microcontroller and which is configured for applying at least two different measuring voltages to the temperature sensor.
