Operating method for a group of pressure sensors

Method (100) for operating a group (1) of pressure sensors,

• wherein the group comprises at least a first pressure sensor (1′) having a first pressure measurement range (4′) and a second pressure sensor (1″) having a second pressure measurement range (4″), wherein the first and second pressure sensors are arranged in such a manner that they can measure the pressure in a common measurement volume (2), wherein the first (4′) and second (4″) pressure measurement ranges overlap in an overlap pressure measurement range (6), and wherein the method comprises the steps of:
• aa) reading out (101) a first measurement signal of the first pressure sensor and a second measurement signal of the second pressure sensor substantially at the same time while the pressure in the common measurement volume is in the overlap pressure measurement range;
• bb) stipulating (102) the first measurement signal which has been read out as the adjustment point for the second pressure sensor;
• cc) determining (103) at least one calibration parameter (K1, K2), in particular a gas-dependent calibration parameter, for the second pressure sensor as a function of the first measurement signal, as a function of the adjustment point as stipulated in step bb) and as a function of the second measurement signal.
