Abstract
A pressure transmitter has a housing () on which a pressure sensor () is fastened. There is provided in the housing a region, produced micromechanically, with reduced wall thickness that forms a separating diaphragm () such that the fluid located in a channel () does not act on the pressure sensor (). The pressure sensor () is connected with a sensor diaphragm () directly to the separating diaphragm via a connecting layer (), thereby rendering possible a highly space-saving design of the pressure transmitter. Consequently, the pressure transmitter can be formed, for example, by the pressure sensor and a channel structure, for example a microreactor, produced in a micromechanical design. A small dead volume in the channel structure is thereby produced in the region of the pressure transmitter.
