Abstract
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.
