The device comprises a converter (32) for converting an analog signal on an operating cycle of the transducer comprising an initial position and a measurement position, into a digital signal, a means (38, 40) for recording the value of the digital signal representing the initial position and the measurement position, and a means (42, 50, 54) for deriving the digital signal according to the difference between the recorded value. It can be applied in particular to displacement recorders for measuring road deformations. <IMAGE>
