The measurement of pressures makes it necessary to connect the pressure sensing element physically with the medium to be measured. For this, the sensing element is provided with metallic or nonmetallic connecting flanges. Until now, there existed the disadvantage that the metallic flanges frequently are not resistant to the aggressiveness and/or corrosiveness of the media to be measured. Nonmetallic connecting flanges are resistant to these media, but are not dimensionally stable at high processing temperatures. It is thus suggested to arrange a connecting pin consisting of a polymer plastic that is resistant to the medium to be measured in a metallic connecting flange in such a way that the medium to be measured may only come in contact with the resistant plastic material, and that the temperature-dependent dimensional stability of the plastic part is insured by an axial and radial support by the metallic flange.
