There is described a differential pressure sensor made using glass-silicon technology with a diaphragm plate arranged between two carrier plates. To achieve a high resolution at the beginning of the measuring range in conjunction with high overload resistance, the measuring diaphragm plate of the sensor has for a prescribed measuring range within the same measuring chambers a plurality of mutually independent deflectable regions as measuring diaphragms. Each such region acts as a part-sensor with a part-measuring range. The part-measuring ranges of the part-sensors overlap and in total are equal to the prescribed measuring range of the differential pressure sensor. The displacement of the measuring diaphragm of each part-sensor is mechanically limited outside its part-measuring range by the carrier plates.
