The arrangement includes an absolute pressure sensor (4) connected to a high pass filter (5) whose time constant is larger than that of the pressure variations to be measured and smaller than that of the pressure variations in the ambient air. The input of the high pass filter is directly connected to the absolute pressure sensor without an amplifier connected between them. The output of the high pass filter is connected to an amplifier (6). The high pass filter can be in the form of an active filter.
