• History
– Eugene Bourdon patented in 1849
– Also in 1849, Bernard Schaeffer in Magdeburg, Germany patented a successful diaphragm pressure gauge, which,
together with the Bourdon gauge, revolutionized pressure measurement
– Widely adopted at the time because of its superior sensitivity, linearity, and accuracy
• Old technology
– 9 moving parts
