摘要： A pressure difference measuring cell for registering pressure difference between a first pressure and a second pressure, comprises: an elastic measuring arrangement having at least one measuring membrane, or diaphragm, that comprises silicon; a platform, which is pressure-tightly connected with the elastic measuring arrangement; a first hydraulic path for transferring a first pressure onto a first surface section of the elastic measuring arrangement; and a second hydraulic path for transferring a second pressure onto a second surface section of the elastic measuring arrangement. The first pressure opposes the second pressure, and the elastic deflection of the measuring arrangement is a measure for the difference between the first and the second pressure, wherein the pressure difference measuring cell has additionally at least one hydraulic throttle, characterized in that the at least one hydraulic throttle comprises porous silicon.
