A measuring device for detecting operating characteristics in a motor vehicle, the variation with time of which characteristics can be represented, in particular, by means of variable frequency components, comprising an inductance (L) as sensor and a circuit exhibiting at least one operational amplifier (30), which is connected to the inductance, is proposed. The measuring device is characterised by the fact that the electronic circuit is constructed in such a manner that the inductance (L) is operated at least approximately in short-circuit mode. This results in the crest value of the output signal amplitude of the measuring device being largely independent of the frequency of the measurement variable. <IMAGE>
