A circuit arrangement with a differential transformer is proposed, the transformer core (8) of which is used as a distance sensor. To eliminate temperature influences and other influences impairing the measurement result, it is provided that the aggregate voltage of the two secondary coils (4, 5) is kept constant by regulating the primary voltage (Up). This, at the same time, results in a linearisation of the distance signal. <IMAGE>
