The invention relates to a pressure-measuring device (M 1 ) with a controller (C) for controlling the functions of the measuring device (M 1 ) and/or for processing measured data, a sensor (S 1 ) for measuring a variable (p 1 ) to provide first measured data (I 1 ), and an output interface (IA 1 , D 1 ) for outputting the measured data (I 1 ). In order that additional measured data of a second measuring device (M 2 ) can be easily processed without using another external data processor or an arrangement with a capillary line in the case of a differential pressure-measuring device, it is proposed that the measuring device (M 1 ) have a communications interface (I 2 C 1 , I 2 C) for an additional, second measuring device (M 2 ) with another sensor (S 2 ) for measuring a variable (p 2 ) to provide second measured data (I 2 ), and, when the second measuring device (M 2 ) is connected via the communications interface (I 2 C 1 , I 2 C, I 2 C 2 ) or the second measuring device (M 2 ) is activated, the controller (C) initiates a reception of the second measured data (I 2 ), a joint processing of the first and second measured data (I 1 , I 2 ; DeltaI=I 1 -I 2 ) and an output of jointly processed measured data (DeltaI).
