Abstract (en)
[origin: WO2004098679A1] The invention relates to a device (1) for measuring the pressure of a medium (28), in particular a liquid medium. Said device comprises a measuring chamber (10), through which the medium flows and which has at least one elastically deformable wall (12), at least one wall (14) that is more rigid in comparison to said first wall and an inlet (20) and outlet (22) for the medium. To measure the impedance, at least one excitation electrode (30) is provided in or on the more rigid wall (14) of the measuring chamber (10) and at least one signal electrode (32) is provided in or on the elastically deformable wall (12).
