Abstract
A pressure transmission device includes a main part and a separating membrane secured to the main part. A pressure chamber is formed between the separating membrane and a surface, with the pressure chamber communicating with a hydraulic path. The separating membrane is: supplied with the process medium from a first membrane side; the pressure chamber and the hydraulic path are filled with a transmission fluid; the separating membrane is connected to the main part; and the separating membrane has a central region. The device additionally comprises a temperature sensor and a mount, wherein the temperature sensor introduced into the mount. The mount is arranged in a central cavity in such a way that a surface of the mount facing the separating membrane lies on a plane relative to the central region such that the surface of the mount acts as an abutment for the separating membrane when pressure is applied.
