The invention relates to a pressure-measuring device (10) and to a method for measuring pressure using such a pressure-measuring device (10). The pressure-measuring device (10) has a pressure-measuring unit (11), wherein the pressure-measuring unit (11) has a rotary body (14a) for example, and the pressure-measuring unit (11) can be designed as a gas-friction manometer (11a). The pressure-measuring device (10) additionally has a unit (21) for detecting/determining characteristic properties of the pressure-measuring unit (11, 11a), said unit being provided in particular in order to detect the rotational frequency of the rotary body (14a) and being part of the pressure-measuring unit (11, 11a) or being paired with the pressure-measuring unit (11, 11a). In order to improve the performance of the pressure-measuring device (10), in particular in areas with strong electromagnetic fields and radiation, the unit (21) is designed as an optical device (25) for detecting/determining characteristic properties of the pressure-measuring unit (11, 11a), in particular in order to detect/determine the rotational frequency of the rotary body (14a).
