  • 19.2 Mechanical pressure sensing elements

    Mechanical pressure-sensing elements include the bellows, the diaphragm, and the bourdon tube. Each of these devices converts a fluid pressure into a force. If unrestrained, the natural elastic properties of the element will produce a motion proportional to the applied pressure. Bellows resemble an accordion constructed from metal instead of fabric. Increasing pressure inside a bellows unit causes it…
