Use a stable surface to place it on or against to avoid knocks and bumps.Īs you would have gathered by now, barometers came a long way since Evangelista Torricelli invented the first one in 1643.

Avoid areas that experience wind or drafts.

Do not place it close to any source of heat.

Always place a barometer in a shaded area.

When placing your barometer, it is important to keep the following in mind: Where To place A BarometerĪ barometer is designed to be placed indoors or outdoors, depending on your needs. Most home weather stations use them, and they can even be found in a number of smartphones. Detection cells are small and versatile and can be integrated into a variety of devices for various purposes. The changing capacity impacts the strength of the electrical current flowing through it, which is measured to calculate the air pressure. The open end is positioned at the bottom inside the mercury. A glass tube with one end sealed is placed in the center of the container. 1) How A Mercury Barometer WorksĪ mercury barometer (also known as a Torricellian barometer) consists of an open flat container filled with mercury. However, each one use a different method of measuring, and also use unique components in its design. How Does A Barometer Work?Īll barometers are designed to measure atmospheric pressure. Now that the most relevant devices were identified, we can examine how each one works.

(There are other types of barometers, but the ones mentioned are the most significant.) The 4 instruments just discussed are the most common and relevant types of barometers. To find out what a weather station measures, and the sensors they use, read the following detailed article. Just remember, a barometer is just one small part of a weather station, which consists of a number of sensors measuring the different weather components. It consists of a detection cell that is sensitive and responds to air pressure.

These electronic devices are widely used in modern homes and professional weather stations, as well as various modern appliances.

One or a series of these chambers are connected to spring, which drives different forms of measuring indicators. (He was also responsible for developing the barograph.) The aneroid barometer was invented in 1844 by Lucien Vidi, a French physicist. This simple device consists of a sealed glass container with a long narrow open spout connected to it. It was invented by Johann Wolfgang Von Goethe, which is why it is also called the "Goethe Barometer." The water barometer we are familiar with today is better known as a weather ball barometer.

It uses an open flat pan and a sealed vertical glass tube filled with mercury to measure changes in air temperature. Invented by Evangelista Torricelli in 1643, as discussed in the previous section, the mercury barometer is one of the earliest barometers ever designed. Each one will be briefly described, and in the next section, we will look at how each one works. Since each barometer functions in a different way, it will then be possible to look at each one separately and describe how it works.īarometers can be divided into four main types. It is also used to measure altitudeīefore looking at how they work, the different types of barometers first need to be identified. It is a crucial part of a weather station and is primarily used in combination with other instruments to determine current and future weather conditions. The Different types of barometersĪs stated in the introduction, a barometer is a meteorological instrument that measures the atmospheric pressure of air in the environment. As a result, he successfully used mercury and became known as the inventor of the mercury thermometer.īlaise Pascal became aware of Torricelli's design, and over time, went on to test and perfect Torricelli's design. He realized he needed a liquid heavier than water to conduct his experiment. Torricelli continued to work in secret due to the politics and beliefs of the time. This argument was not supported and believed by most of his peers, including Galileo. Torricelli was the first scientist who concluded that the air in the atmosphere had weight and exerted pressure on objects below it. Since no evidence of an actual experiment could be found, Evangelista Torricelli is widely acknowledged as the inventor of the barometer in 1643.

In early 1631, French designer René Descartes described the design of a trial to measure air pressure.
