Abstract
A pressure sensor arrangement () for measuring a pressure of a fluid is described, the sensor arrangement () comprising a connector housing () having a fluid opening () and a fluid chamber () in connection with the fluid opening (), at least one pressure sensitive element (), a membrane () arranged between the pressure sensitive element () and the fluid chamber (), and pressure attenuation means (). Such a pressure sensor arrangement should be able to protect the measuring membrane from high frequency pressure pulsations with low costs. To this end the pressure attenuation means () are arranged in the fluid chamber () in direct contact with the membrane () separating the membrane () from the fluid in the fluid chamber and comprise a homogenous incompressible material having a mechanical loss factor of 0.1 or higher at frequencies of 200 Hz or higher.
