    摘要: A pressure gauge, or transducer, for high-temperature applications, comprising a sensor module with a sensor body having a measuring cell chamber containing a pressure measuring cell. The pressure measuring cell can be subjected to the action of a pressure via a first hydraulic path filled with a transmission liquid. The pressure gauge also comprises a transmission module for transmitting a pressure to the first hydraulic path. The transmission module has a second hydraulic path, which is filled with a transmission liquid and extends from a process diaphragm, through a transmission body and to a transmission diaphragm. The transmission diaphragm is attached to the transmission body in a pressure-tight manner, and the sensor body is joined to the transmission body in a pressure-tight manner, whereby the transmission diaphragm communicates with the first hydraulic path so that the pressure of the second hydraulic path can be transmitted via the transmission diaphragm to the first hydraulic path.
