Method for determining a pressure in a pressure cell, the method consisting in determining a measuring signal (x) that is at least proportional to a measured pressure in the pressure cell, generating an output signal (y) from the measuring signal (x) using a filter unit (10) comprising a transfer function by at least reducing, preferably eliminating, a noise signal contained in the measuring signal determining a change over time of the measuring signal (x), and setting the transfer function as a function of the change over time of the measuring signal (x). A measuring cell arrangement is also specified.
