A diaphragm seal for transmitting media pressure, comprising: a diaphragm-carrier body having a media-side surface and a separating diaphragm, which is connected to the diaphragm-carrier body in a pressure-tight manner along at least one periphery. A pressure chamber is formed between the separating diaphragm and the diaphragm-carrier body, and a temperature-isolation body having a channel, which can be filled with a transmission fluid, in order for the pressure chamber of the diaphragm-carrier body attached to a first front side to be connected to a pressure transducer which can be connected to a second front side, so that media pressure prevailing at the separating diaphragm can be transmitted to the pressure transducer. On the temperature-isolation body, on its outer surface, a plurality of successive and, in particular, undulating cooling ribs for emitting heat are formed, and wherein the minimum cross-sectional diameter of the temperature-isolation body between the cooling ribs, which follow one after the other along the section, decrease from the first front side to the second front side.

Diaphragm seal and pressure sensor having a diaphragm seal

A flange for a corrosion resistant and nevertheless low cost flange for pressure measurement cells, or pressure transfer means, is composed essentially of a metal foundation of a standard material and is protected on the side facing a process medium by a there applied layer of a highly alloyed, special material.
