aneroid

aneroid
A thin, disc-shaped box or capsule, usually metallic, partially evacuated of air and sealed, which expands and contracts with changes in atmospheric or gaseous pressure. The aneroid is the sensing and actuating element in various meters or gages, such as barometers, altimeters, and manifold-pressure gages. It is also the triggering or operating element in various automatic mechanisms. A device similar to an aneroid but open to outside pressures, such as the capsule in an air-speed indicator, is not commonly called an aneroid.
