1. A diaphragm seal system comprising: a pressure measurement instrument with an elastic measuring element provided therein, the pressure measurement instrument having a pressure connection at one end thereof, the pressure connection being provided with an external thread that forms a threaded section of the pressure measurement instrument;a connected analysis device that displays pressure values on a display;a measurement connection flange having a measurement membrane;an adapter that connects the pressure measurement instrument to the measurement connection flange,wherein a fluidic pressure connection between the measurement membrane and the elastic measuring element being established through a pressure path of the adapter,wherein the adapter has, at least on a first end, a recess that accommodates the threaded section of the pressure measurement instrument,wherein the threaded section is inserted into the recess of the adapter and is connected to the adapter by a circumferential weld, such that the entire adapter is positioned to an exterior of the pressure measurement instrument, andwherein a second end of the adapter is attached to a first surface of the measurement connection flange and the measurement membrane is attached to a second surface of the measurement connection flange, the first surface opposing the second surface. 2. The diaphragm seal system according to claim 1, wherein the recess of the adapter is conical and wherein the threaded section of the pressure measurement instrument is conical, and is supported in the conical recess of the adapter. 3. The diaphragm seal system according to claim 1, wherein the adapter has cooling fins formed thereon or has a relatively long insulating section. 4. The diaphragm seal system according to claim 1, wherein the pressure connection of the pressure measurement instrument is provided with a collar that sits on or is inserted into the adapter and that is welded to the adapter. 5. The diaphragm seal system according to claim 1, wherein the recess of the adapter is provided with a vertical or horizontal channel that stands in connection with the pressure path of the adapter. 6. The diaphragm seal system according to claim 1, wherein the pressure path of the adapter has a bore diameter of 0.5-2.0 mm. 7. The diaphragm seal system according to claim 1, wherein the pressure connection of the pressure measurement instrument has recesses on portions of the threads of the threaded section that are stamped, milled, or formed. 8. The diaphragm seal system according to claim 1, wherein the external thread of the pressure measurement instrument is a quarter inch or half inch thread that has a conical shape. 9. The diaphragm seal system according to claim 1, wherein the elastic measuring element is a Bourdon tube or a membrane. 10. The diaphragm seal system according to claim 1, wherein the adapter is made of stainless steel. 11. The diaphragm seal system according to claim 1, wherein the adapter has a fill opening that is closed with a pin or plug. 12. The diaphragm seal system according to claim 1, wherein the adapter has a recess formed on its circumference in the form of a bore. 13. The diaphragm seal system according to claim 1, wherein a side wall and a bottom wall of the recess of the adapter are each provided with a recessed channel. 14. The diaphragm seal system according to claim 1, wherein the measurement connection flange has a bore extending therethrough, the bore of the flange being aligned with and connecting to the pressure path of the adapter. 15. A diaphragm seal system comprising: a pressure measurement instrument with an elastic measuring element, the pressure measurement instrument having a pressure connection at one end thereof, the pressure connection being provided with an external thread that forms a threaded section of the pressure measurement instrument;a connected analysis device that displays pressure values on a display;an adapter that connects the pressure measurement instrument to a measurement connection having a measurement membrane, a fluidic pressure connection between the measurement membrane and the elastic measuring element being established through a pressure path of the adapter,wherein the adapter has, at least on one side, a recess that accommodates the threaded section of the pressure measurement instrument,wherein the threaded section is connected to the adapter by a circumferential weld, andwherein the adapter has a fill opening that is closed with a pin or plug, and is additionally covered with an identification plate or sticker to protect from contamination. 16. The diaphragm seal system according to claim 15, wherein the adapter has a recess formed on its circumference in the form of a bore that is suitable for accommodating and orienting during assembly, and wherein the fill opening of the adapter is at a same height or on a same axis as, or is oriented opposite to, the recess for assembly.
