A
Barometer is an important engineering device used in various applications.
This instrument is widely used for measuring atmospheric pressure. The
instrument provides high precision readings for students and professionals.
Types of Barometers
- Liquid Barometers : This type of barometer can further be
classified into water and mercury based barometers. Mercury based
barometers have been more successful than the water based barometers.
- Aneroid Barometers : This type of barometer makes use of a
small and flexible metal box, also known as an aneroid cell. The cell is
filled with air and tightly sealed, some of the air is then removed and
changes in the external air pressure cause the cell to either expand or
contract. This movement causes the mechanical lever to move, thereby
measuring the atmospheric pressure.
Use of Barometer
