Abstract: A device and method for calibrating a first pressure sensor. The method includes: a) recursive analysis and forecasting of at least one correction function for finding a correction signal for the correction of a drift signal with the aid of a corresponding pressure reference signal, which is measured by the first pressure reference sensor, at constant internal pressure and at constant internal tube temperature; b) first calibration of a force signal, measured by the first pressure sensor and corrected using the correction signal, with the pressure reference signal, which is measured by the first pressure reference sensor, prior to an active use of the tube; and c) second calibration of the force signal, measured by the first pressure sensor and corrected using the correction signal, with the pressure reference signal, which is measured by a second pressure reference sensor during an active use of the tube.
