A sensor is suggested for measuring physical dimensions as well as a method for balancing its measuring values, whereby an evaluation circuit is used for the calculation of the accurate measuring value. The sensor (10) is combined with a PROM (15) into a structural unit (19), whereby the correction values for the measuring signals of sensor (10) are stored in PROM (15). Sensor (10) and PROM (15) have at least one output (18) through which the measuring signals as well as the correcting data have to be transmitted to evaluation circuit (30).
