Abstract

See full text

A diaphragm seal for transmitting the pressure of a process medium includes a main body having a surface and a separating membrane secured to the surface, thereby forming between the separating membrane and the surface a pressure chamber which communicates, via an opening in the surface, with a hydraulic path. The separating membrane can be exposed to the process medium on a first side, and the separating membrane has a central middle region. The diaphragm seal further includes a temperature transducer for determining a temperature measurement variable of the process medium, which is secured in the middle region on a second side of the separating membrane, and the main body is joined to the separating membrane such that a transmitting fluid, which fills the pressure chamber and the hydraulic path, does not come into contact with the temperature transducer.
