Method for operating a group of pressure sensors (1', 1'') which are arranged to measure the pressure in a common measurement volume, wherein the group of pressure sensors comprises at least a first pressure sensor having a first pressure measurement range and a second pressure sensor having a second pressure measurement range, wherein the first and second pressure measurement ranges overlap in an overlap pressure measurement range, wherein the first pressure sensor is based on a first indirect pressure measurement principle and is adapted to output a first measurement signal calibrated to a reference gas (G ref), wherein the second pressure sensor is based on a second indirect pressure measurement principle and is adapted to output a second measurement signal calibrated to the reference gas, characterized in that the method comprises the steps of: a) providing gas-type-specific first calibration data (K 1 [G i]) for the first measurement signal and gas-type-specific second calibration data (K 2 [G i]) for the second measurement signal, wherein the first and second calibration data describe a dependence of the first and second measurement signals, respectively, on the effective pressure (p eff) and on a gas type in the common measurement volume for a list of gas types comprising at least one first gas type (G 1) which is different from the reference gas; b) substantially simultaneously recording a first measured value (p 1) of the first measurement signal and recording a second measured value (p 2) of the second measurement signal; c) determining a resultant gas type (G*) as that gas type in the list of gas types which best matches the combination of the recorded first measured value (p 1) and the recorded second measured value (p 2), taking into account the first and second calibration data. wherein the group of pressure sensors comprises at least a first pressure sensor having a first pressure measurement range and a second pressure sensor having a second pressure measurement range, wherein the first and second pressure measurement ranges overlap in an overlap pressure measurement range, wherein the first pressure sensor is based on a first indirect pressure measurement principle and is adapted to output a first measurement signal calibrated to a reference gas (G ref), wherein the second pressure sensor is based on a second indirect pressure measurement principle and is adapted to output a second measurement signal calibrated to the reference gas, characterized in that the method comprises the steps of: a) providing gas-type-specific first calibration data (K 1 [G i]) for the first measurement signal and gas-type-specific second calibration data (K 2 [G i]) for the second measurement signal, wherein the first and second calibration data describe a dependence of the first and second measurement signals, respectively, on the effective pressure (p eff) and on a gas type in the common measurement volume for a list of gas types comprising at least one first gas type (G 1) which is different from the reference gas; b) substantially simultaneously recording a first measured value (p 1) of the first measurement signal and recording a second measured value (p 2) of the second measurement signal; c) determining a resultant gas type (G*) as that gas type in the list of gas types which best matches the combination of the recorded first measured value (p 1) and the recorded second measured value (p 2), taking into account the first and second calibration data. a) providing gas-type-specific first calibration data (K 1 [G i]) for the first measurement signal and gas-type-specific second calibration data (K 2 [G i]) for the second measurement signal, wherein the first and second calibration data describe a dependence of the first and second measurement signals, respectively, on the effective pressure (p eff) and on a gas type in the common measurement volume for a list of gas types comprising at least one first gas type (G 1) which is different from the reference gas; b) substantially simultaneously recording a first measured value (p 1) of the first measurement signal and recording a second measured value (p 2) of the second measurement signal; c) determining a resultant gas type (G*) as that gas type in the list of gas types which best matches the combination of the recorded first measured value (p 1) and the recorded second measured value (p 2), taking into account the first and second calibration data.
