A diaphragm construction for a process measuring device comprises a sensing element arranged in a functional connection with a process medium to be measured, a part exterior of the process medium, comprising a measuring means, a lever-like transfer element to transmit a force effect exerted on the sensing element to the measuring means, and a diaphragm to isolate the process medium from the exterior part. The transfer element comprises a first rod part arranged to be placed in a process medium flow channel and a second rod part arranged to be placed in a part of the process measuring device exterior of the process. A fixing element is arranged to be placed in connection with the second rod part of the transfer element, the fixing element comprising a supporting portion and a fixing portion, wherein the diaphragm is arranged to be clamped between the fixing portion and the second rod part.
