The measurement value pick-up (1) outputs an alternating analog signal which represents the movement of its sensor (4) and forms a calibrated unit with a supply and output connecting part (2) into which circuit arrangements are integrated which are suitable for compensating for the linearity errors of the signal/movement response curve. For this purpose, the connecting part (2) comprises the following elements: - a converter circuit (11) for converting the alternating signal at the output of the sensor into an analog direct-voltage signal; - an analog/digital converter (12) for converting this converted signal; - a memory (13) in which the linearity errors in question are stored at addresses which correspond to certain measurement sectors, - a correction circuit (14) in which the value of a stored error is in each case added to the uncorrected value of the corresponding measurement sector which is represented by the output signal of the analog/digital converter (12). <IMAGE>
