Abstract: A pressure transducer having a sensor module comprises a sensor body including a measuring cell chamber, in which a pressure measuring cell is contactable with a pressure via a first hydraulic path filled with a second pressure transfer liquid, and a transfer module for transferring a pressure to the first hydraulic path. The transfer module has, filled with a first pressure transfer liquid, a second hydraulic path, which extends from a process diaphragm through a transfer body to a transfer diaphragm. The transfer diaphragm is secured pressure-tightly on the transfer body. The sensor body is connected pressure-tightly with the transfer body in such a manner that the first hydraulic path is in communication with the transfer diaphragm such that the pressure of the second hydraulic path is transferable through the transfer diaphragm to the first hydraulic path.
