Abstract

The invention relates to a pressure-measuring device (M1) with a controller (C) for controlling the functions of the measuring device (M1) and/or for processing measured data, a sensor (S1) for measuring a variable (p1) to provide first measured data (I1), and an output interface (IA1, D1) for outputting the measured data (I1). In order that additional measured data of a second measuring device (M2) 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 (M1) have a communications interface (I2C1, I2C) for an additional, second measuring device (M2) with another sensor (S2) for measuring a variable (p2) to provide second measured data (I2), and, when the second measuring device (M2) is connected via the communications interface (I2C1, I2C, I2C2) or the second measuring device (M2) is activated, the controller (C) initiates a reception of the second measured data (I2), a joint processing of the first and second measured data (I1, I2; ΔI=I1−I2) and an output of jointly processed measured data (ΔI).
