A pressure difference measurement transmitter comprising: a pressure difference sensor; a first process connection flange; and a second process connection flange. The pressure difference sensor is clamped between the first process connection flange and the second process connection flange, and between a first and a second seal. The pressure difference sensor is contactable by a first media pressure via the first process connection flange and by a second media pressure via the second process connection flange; and a housing, which contains an electronic evaluating circuit. The housing has an input opening, through which the evaluating circuit is connected to the pressure difference sensor; and wherein the housing has at least one appendage, which extends between the first and the second process connection flanges; wherein the appendage is clamped in parallel with the pressure difference sensor between the flanges, so that the housing is held by the clamped appendage.
