Abstract:
An inlet diaphragm construction for a process measuring device operable for measuring a process medium flowing in a process medium flow channel, which comprises:a sensing element arranged in a functional connection with the process medium flowing in the process medium flow channel,a part exterior of the process medium flow channel, comprising a measuring means for measuring a force effect exerted on the sensing element,a lever-like transfer element having a longitudinal axis to transmit the force effect exerted on the sensing element to the measuring means, anda diaphragm having a thickness to isolate the process medium from the exterior part, wherein the lever-like 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 the part of the process measuring device exterior of the process, and further comprising a fixing element formed separately from and connected with the second rod part of the transfer element and comprising a supporting portion and a fixing portion, the diaphragm being clamped between the fixing portion and the second rod part such that the fixing element sealingly attaches the diaphragm to the second rod part independently of position of the first rod part with respect to the fixing portion of the fixing element.
