Abstract:
1. A differential pressure sensor for measuring the pressure difference between a pressure acting on a high-pressure side and a pressure acting on a low-pressure side, comprising: A measuring mechanism having: a chamber on the high-pressure side that is sealed by a first dividing membrane and filled with a transfer medium, said first dividing membrane is loaded with a pressure acting on the high-pressure side; a chamber on the low-pressure side that is sealed by a second dividing membrane and filled with a transfer medium, said second dividing membrane is loaded with a pressure acting on the low-pressure side; a pressure-sensitive element which separates said chamber on the high-pressure side from said chamber on the low-pressure side; and a single throttle for damping overload pulses; wherein: said throttle is arranged on the low pressure side between said pressure-sensitive element and said second dividing membrane; and no throttle is arranged on the high pressure side.
