ABSTRACT:
A pressure measurement device, a receiving tube, in which a pressure sensor element is axially clamped by means of a screw element. Between the screw element and the pressure sensor element, a transmission element is arranged to transmit axial clamping forces. The pressure measurement device exhibits at least one first stop, which is not rotatable relative to the receiving tube, wherein the transmission element exhibits at least one second stop, which is engaged with the at least one first stop, in order to prevent a rotation of the transmission element. In this way, a transmission of torque to the pressure sensor element during assembly is prevented. Preferably the first stop is arranged on a bushing which centers the pressure sensor element in the receiving tube.
