摘要： A differential pressure sensor includes a measuring mechanism having a chamber on the high-pressure side that is sealed by a first dividing membrane, and a chamber 6 on the low-pressure side that is sealed by a second dividing membrane. The first dividing membrane is loadable with a pressure acting on the high-pressure side and the second dividing membrane with a pressure acting on the low-pressure side, and the chamber on the high-pressure side is separated from the chamber on the low-pressure side by a pressure-sensitive element, especially a measuring membrane, and the chambers of the high- and low-pressure sides are filled with a transfer medium. For damping of overload pulses acting on the first dividing membrane on the high-pressure side, a hydraulic throttle is provided, which is arranged on the low-pressure side between the second dividing membrane and the pressure-sensitive element.
