Device for measuring pressure
First Claim
1. Device for measuring the pressure of a liquid medium, said device comprising a measuring chamber through which the medium can flow and which has at least one elastically deformable wall, at least one wall that is more rigid by comparison to said deformable wall, and an inlet and outlet for the medium, wherein at least one excitation electrode is provided in or on the at least one more rigid wall of the measuring chamber, and at least one signal electrode is provided on the elastically deformable wall wherein a measure of impedance between the electrodes as a liquid medium flows through the measuring chamber serves to measure the pressure of the liquid medium.
