Answer:

Aneroid Barometer

Barometers are very useful devices which help us to predict the weather. You can say it assists us in preparing for the changes in the weather beforehand. Moreover, we can also use mercury or aneroid barometer for detecting any changes in the altitude. It uses the changes that happen in air pressure to do so. For instance, bad weather is indicated by low air pressure.

Similarly, barometers are of different types depending on their characteristics. There are mainly two types of barometer that are mercury and aneroid barometer. Each has its own specifications and works in their own individual manner.

Aneroid Barometer Mechanism

A metal cell which contains a small amount of air or a series of these cells combined together operate the aneroid barometer. When the air pressure increases, the sides of these cells come together quickly. The base of the instrument secures one side.

After that, the other side joins the structure of pulleys and levers to a rotating pointer, which moves over a scale on the face of the instrument. This pointer is generally found in black colour.



Moreover, the aneroid barometer comprises of a small capsule which has quite flexible sides. The air has been pumped out of this capsule. Therefore, whenever there is a change in the pressure, the thickness of this capsule changes.

Similarly, whenever there is an increase in the pressure of the atmosphere, the sides of the capsule become compressed. This capsule attaches to a lever which keeps moving the needle as and when the air pressure keeps squeezing the capsule.

This results in registering a higher reading on the scale. These changes are thus magnified by levers and are causes the pointer to move on a dial which is behind the needle. Finally, you will have your weather forecast on a digital read-out device.

Explanation:

Uses of Aneroid barometer are----

Aneroid barometers primarily measure whether pressure is rising or falling. This type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense. There are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level. Another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper. When used in this capacity, the aneroid barometer can store a week's worth of data.
