What is the difference between a Bourdon gauge and a barometer?

Answer 1

A barometer measures the pressure of the atmosphere. A manometer measures the pressure of something (most often a gas) inside a container. Some simple manometers actually measure the difference between the pressure inside the container and atmospheric pressure outside.

Answer 2

A barometer is a type of manometer

hye,pls give answer with difference.

Manometer is an instrumental device designed to measure pressure of fluids.

Barometer is a type of manometer that specifically measures the pressure of atmosphere.

Medically, I think the word Baroreceptor in the human brain is a misnomer. It measures the pressure of blood and should have been named Manoreceptor just as the right atrium is called as pulmonary circulation manometer.

Answer 3

A Bourdon gauge is used to measure gas pressure, which means the pressure of the gas inside someting, like tires. A barometer is used to measure air pressure (atmospherice pressure), which is the pressure of the air exerting on us.

In addition to this answer the pressure being measured usually enters the inside of the tube, the outside being at atmospheric pressure.

A Bourdon tube barometer was used for early barometric pressure measurements, but was far less sensitive to the traditional Vidi bellows used in the established design. In this design the air pressure acts on the external surfaces of the tube of bellows, the internals are evacuated of almost all air.

To prevent collapse of the Vidi system a powerful spring prevents the bellows from collapsing under the weight of the air pressure.

Answer 4

Barometer is the device used for measuring atmospheric pressure.Whereas,altimeter is the instrument that measures the altitude of the land surface or of any object, such as an airplane.
