Pressure measuring device for measuring a pressure, comprising: - a pressure measuring cell; - a rotationally symmetrical sensor bushing into which the pressure measuring cell is inserted; - a rotationally symmetrical process connection for detachably fastening the pressure measuring device to a wall of a measuring point, wherein the process connection has at one end a circumferential stop surface extending inwards and intended for the sensor bushing and at another end an opening for receiving the sensor bushing, wherein the sensor bushing with the pressure measuring cell is inserted in an installed state through the opening as far as the stop surface into the process connection, so that the pressure measuring cell is introduced into the measuring point substantially flush with the front; - a ring-like process seal, which runs radially in a ring-like manner in a sealing plane between the sensor bushing and the stop surface of the process connection and seals in order to prevent the process medium from penetrating into the pressure measuring device characterized in that - the stop surface of the process connection and/or a counter-stop surface of the sensor bushing, which is directed towards the stop surface in the installed state, have a plurality of individually formed webs which are formed in such a manner, that, in the installed state, a plurality of openings with a defined height and a width defined by the arrangement of the webs are formed between the mating stop surface of the sensor bushing and the stop surface of the process connection, the plurality of openings together forming a fluidic path network consisting of a plurality of individual fluidic paths (EP1-EP4) running parallel to one another, via which, in the event of a failure of the process seal, the process medium is conducted from the sealing plane at the process seal to at least one leakage opening which is visible from the outside when the pressure measuring device is installed, the webs being designed in such a way, that a sum of the individual cross-sections of the plurality of openings corresponds to a predetermined minimum cross-section, the defined height and the defined width being used to calculate the individual cross-sections, and the webs being designed as a function of the properties of the process seal in such a way that the process seal does not extrude into the openings. - a pressure measuring cell; - a rotationally symmetrical sensor bushing into which the pressure measuring cell is inserted; - a rotationally symmetrical process connection for detachably fastening the pressure measuring device to a wall of a measuring point, wherein the process connection has at one end a circumferential stop surface extending inwards and intended for the sensor bushing and at another end an opening for receiving the sensor bushing, wherein the sensor bushing with the pressure measuring cell is inserted in an installed state through the opening as far as the stop surface into the process connection, so that the pressure measuring cell is introduced into the measuring point substantially flush with the front; - a ring-like process seal, which runs radially in a ring-like manner in a sealing plane between the sensor bushing and the stop surface of the process connection and seals in order to prevent the process medium from penetrating into the pressure measuring device characterized in that - the stop surface of the process connection and/or a counter-stop surface of the sensor bushing, which is directed towards the stop surface in the installed state, have a plurality of individually formed webs which are formed in such a manner, that, in the installed state, a plurality of openings with a defined height and a width defined by the arrangement of the webs are formed between the mating stop surface of the sensor bushing and the stop surface of the process connection, the plurality of openings together forming a fluidic path network consisting of a plurality of individual fluidic paths (EP1-EP4) running parallel to one another, via which, in the event of a failure of the process seal, the process medium is conducted from the sealing plane at the process seal to at least one leakage opening which is visible from the outside when the pressure measuring device is installed, the webs being designed in such a way, that a sum of the individual cross-sections of the plurality of openings corresponds to a predetermined minimum cross-section, the defined height and the defined width being used to calculate the individual cross-sections, and the webs being designed as a function of the properties of the process seal in such a way that the process seal does not extrude into the openings.
