Abstract
A pressure gauge for measuring a pressure includes: a pressure measuring cell; a rotationally symmetric sensor bushing configured to accept the pressure measuring cell; a rotationally symmetrical process connection for releasably attaching the pressure gauge to a measuring point; a process seal to prevent the process medium entering the pressure gauge; the process connection and/or the sensor bushing having multiple individual recesses configured such that the individual recesses together form a fluidic path group of multiple fluidic individual paths extending parallel to one another, by means of which, in the event that the process seal fails, the process medium is conducted from a sealing plane for the process seal to at least one opening visible from the outside when the pressure gauge is in an installed state, the individual recesses configured such that a total cross-sectional area of the recesses forming the path group has a predefined minimal cross-sectional area.
