BarometerThis barometer was designed and made in the mid 19th century by Eugene Bourdon (1808-84), a French engineer and inventor. It is a type known as an aneroid barometer (from the Greek, meaning 'not wet'). The barometer has a curved evacuated tube which variations in the atmospheric pressure cause to flex, thus moving the pointer. The pressure is indicated by the scale on the outside of the dial. Eugene Bourdon's aneroid barometer is derived from his metallic manometer for measuring pressures in steam engines, which he produced in 1849. It was never as popular as the Vidie pattern of aneroid barometer. Record detailsTo search on related items, click any linked text below.
