Pressure gauge with pressure gauge assembly and connecting assembly

摘要

A pressure gauge comprises a pressure gauge assembly and a connecting assembly. The pressure gauge assembly includes a measuring pressure port for the pressure to be measured and the connecting assembly includes a pressure measuring port. The pressure gauge assembly is adapted to be connected to the connecting assembly. In order to permit a relative rotation between the pressure gauge assembly and the connecting assembly, the pressure gauge assembly and/or the connecting assembly supports at least one annular passage section connecting the measuring pressure port to the pressure measuring port.
