The invention relates to a sensor for locating metallic or magnetizable objects, comprising two emission coils and a receiving coil which are inductively interconnected. In the method for determining the influence of the temperature on the sensor, a first pair of predetermined alternating currents are applied to the emitter coils and simultaneously, flows which pass through the emitter coils and a first current of the receiver coil are sampled. Subsequently, a second pair of predetermined alternating currents are applied to the emitter coils and simultaneously, flows which pass through the emitter coils and a second current of the receiver coil are sampled. Based on the determined flows and voltages, coupling factors between the emitter coils and the receiver coils can then be determined and the object is determined based on the coupling factors. |
