Abstract (en)
[origin: WO2005017481A1] Disclosed is a compact differential pressure sensor that has a simple structure and a symmetrical design. Said differential pressure sensor comprises a sensor element (1), two pressure measurement chambers (2, 3) that are located next to said sensor element (1), two pressure-absorbing chambers (22, 32) which are closed by two separating membranes (21, 31), and two overload chambers (23, 33) separated from each other by means of an overload membrane (6). Said overload membrane (6) is provided with a closed outer edge and a closed inner edge and is clamped in a fixed manner along the outer and inner edge thereof. The sensor element (1) is disposed within the inner edge of the overload membrane (6) when projected onto a plane that is defined by the overload membrane (6).
