A pressure measuring device ( 2 ) includes a vibrating ferromagnetic cylinder ( 4 ) and mechanically located within a casing ( 6 ). A diaphragm ( 24 ) is directly connected to the cylinder and forms a pressure measurement surface. Pressure on the diaphragm ( 24 ) results in a force and stresses in the cylinder ( 4 ) which change the resonant frequency of the vibrating cylinder.
