aneroid
Dry pressure gauge
Aneroid describes something that operates without liquid, specifically a barometer that measures atmospheric pressure using a sealed metal chamber rather than a column of mercury.
An aneroid barometer contains a flexible metal box that expands or contracts with pressure changes, moving a needle across a dial.
The term appears almost exclusively in this technical context.
